Grapevines (Vitis spp.) are affected by many viral diseases which cause serious pathological problems. GLRaV-3 is among the most widespread leafroll viruses, while Grapevine Fanleaf Virus (GFLV) is a destructive pathogen which reduces the lifespan of grapevine. Considering the impact and the spread of these diseases, our objective was to analyse the presence of these two viruses in several grapevine varieties in grapevine collection at ATTC Vlore. Data gathered from plant pathogens serve to better understand and prevent the spread of pathogens, as a mandatory rule for the quality control of certified plant material during vegetative propagation.\u0000Method. The presence of two common viruses were tested using virus specific primers; LC1/LC2 primer pair designed from the hHSP70 gene for detecting Grapevine Leafroll-associated Virus-3 (GLRaV3) and C3390/H2999 primer pair, designed from coat protein coding regions for detecting Grapevine Fanleaf Virus (GFLV), in six varieties; ‘Merlot’, ‘Kallmet’, ‘Shesh i zi’, ‘Shesh i bardhё’, ‘Debinё’, and ‘Pulёz’, provided through a randomised sampling procedure. One Step Reverse Transcription Polymerase Chain Reaction assay was used to detect the viral presence.\u0000Results showed a high (100%) prevalence of GLRaV3 virus in all of analysed samples, as the most frequent among the two pathogens. Analysis for of GFLV virus showed low infection rate, being present in only one sample.\u0000Conclusions. We herein show an efficient, fast and reproducible method for detecting grapevine viruses through one step RT-PCR. Our results suggest that sampling of the infected plant material should be avoided due to the presence of viral infections.","PeriodicalId":53379,"journal":{"name":"Plant Varieties Studying and Protection","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45627294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To establish the optimal row spacing and so­wing rate of sorghum seeds of grain varieties ‘Dniprovskyi 39’ and ‘Vinets’, to substantiate their influence on the growing season and biometric parameters of plants in the Right-Bank Forest-Steppe of Ukraine.\u0000Methods. Field, laboratory, mathematical and statistical.\u0000Results. The most intensive growth and development of sorghum plants was observed when sowing seeds with a row spacing of 45 cm and a seeding rate of 200 thousand pieces/ha. In particular, the duration of the growing season under such conditions was the smallest: 108 days for the ‘Dniprovskyi 39’ variety and 106 days for the ‘Vinets’ variety. At the same time, the indicators of field seeds germination, plant height and stem diameter were maximum in the experiment: ‘Dniprovskyi 39’ – 88.7%, 137.3 cm and 1.7 cm, ‘Vinets’ – 86.9%, 121.8 cm and 1.6 cm, respectively. It was found that an increase in seeding rate reduced indicators of productive tillering, leaf area and weight per plant. The most intense tillering of sorghum plants was observed at a seeding rate of 150 and 200 thousand pieces/ha for all the studied variants of the row spacing: on average, up to two panicles well filled with grain per plant, depending on the varietal characte­ristics. At the rate of 250 thousand pieces/ha, tillering of plants in both varieties was somewhat weaker – 1.0–1.1 panicles per plant. The largest indicators of leaf surface area and weight of one plant were with a row spacing of 45 cm: 1528–2320 cm2 and 169.2–185.6 g in the variety ‘Dniprovskyi 39’ and 1476–2180 cm2 and 143.1–162.3 g in the variety ‘Vinets’ depending on planting density. Reduction of row spacing up to 15 cm and its increase up to 70 cm led to a decrease in the main parameters of plant growth and development.\u0000Conclusions.

Mathematical and statistical: determination of stability and plasticity by Eberhart & Russell method, correlation analysis.\u0000Results. As a result of correlation analysis of millet cultivated areas during the period of 2011–2020, it was revealed that cultivated areas in Ukraine depend on the world ones (r = 0.34). It was determined that a high level of common millet yield was obtained in the forest-steppe zone, namely in Poltava, Khmelnytskyi, Cherkasy, Sumy and Kharkiv regions (2.20–2.51 t/ha). Quite high rates of yield were obtained in Vinnytsia, Kyiv (Forest-Steppe zone) and Kirovohrad (Steppe zone) regions (1.86–2.02 t/ha). Low yield over 10 years was noted in Rivne, Zhytomyr and Volyn regions, which belong to the Forrest zone (1.09–1.34 t/ha). It is shown that during 2011–2015 high variability of millet yield was observed in Khmelnytskyi, Vinnytsia and Volyn regions. The coefficient of variation was 42.0–71.3%. During 2016–2020 significant variation was noted in Donetsk, Volyn and Odesa regions. The coefficient of variation was 31.8–43.9%.

To reveal the influence of the substrate compositions on technical indicators and the chemical composition of the fruiting bodies of the golden oyster mushroom and poplar mushroom.\u0000Methods. The experimental design included cultivation of two species of wood-decay fungi Pleurotus citrinopileatus Singer (strain 2161 IVK) and Cyclocybe aegerita (V.Brig.) Vizzini (strain 2230 IVK) on three variants of substrate composition. Laboratory, laboratory-production methods for evaluating the effectiveness of growing technology, chemical composition of the obtained raw materials, statistical methods of analysis were applied.\u0000Results. The structure and composition of substrates affect the technological characteristics of the culture, physical and chemical properties of fruiting bodies. The shortest fruiting cycle of 35.2 ± 1.7 days was determined for C. aegerita under growing conditions on SC1 substrate which formula included «straw, husks, pellet, rapeseed, corn, and CaCO3» in the ratio of 30: 40: 70: 20: 20: 1. The highest yield (170.5 ± 15.2 g per 1 kg of substrate) in the experiment was determined for P. citrinopileatus on the SC1 substrate composed of «straw / pellets  / rapeseed / corn / CaCO3» in the ratio 40: 90: 20: 25: 1. Fruiting bodies of P. citrinopileatus obtained from the SC3 substrate composed of  «pellets / rapeseed / corn / CaCO3» in the ratio 60: 110: 20: 30: 1 had the highest protein content – 22.47 ± 0.19%, and fruiting bodies from the SC1 substrate had the least amount of proteins – 17.38 ± 2.60%. Fruiting bodies of C. aegerita contained more lipids than those of P. citrinopileatus, but the factor of the influence of the substrate composition on the total amount of lipids for some cultivars was insignificant. The largest amount of endopolysaccharides was isolated from the fruiting bodies of C. aegerita (6.81 ± 0.41%) cultivated on SC3 substrate, and the smallest in the SC1 variant (1.38 ± 0.25%). The content of endopolysaccharides in the fruiting bodies of P. citrinopileatus had less variability from 2.54 ± 0.54 (SC3) to 4.72 ± 0.61% (SC1).\u0000Conclusion.

Investigate the formation and functioning of symbiotic systems of soybeans with nodule bacteria by ino­culation of seeds with biological products based on fungicide-resistant strains of Bradyrhizobium japonicum PC07 and B78 with different rates of synthetic carmoisine colorant.\u0000Methods. Physiological, microbiological, gas chromatography, statistical.\u0000Results. It was found that as a result of inoculation of soybean [Glycine max (L.) Merr] variety ‘Almaz’ with microbial preparations based on B. japonicum PC07 and B78, with the addition of carmoisine (0.25 and 0.5 g per 200 g of the preparation), the amount and the weight of nodules formed on the roots during the growing season were at the level of the control plants or exceeded them. The greatest difference in indicators of quantity and weight of root nodules between plants of control and experimental variants is noted in a phase of full flowering at inoculation by both strains of rhizobia and addition to biological products of various norms of dye. Analysis of nitrogen-fixing activity (NFA) of the formed symbiotic systems showed the absence of a negative effect of the synthetic colorant on its level. When inoculated with soybean seeds B. japonicum PC07 in the phase of three true leaves, NFA was higher by 15.6–25.9% and in the budding-beginning of flowering stage by 7.4–29.5% compared with control plants with the addition of 0.25 and 0.5 g of carmoisine, respectively. Against the background of bacterization of soybean seeds by strain B78 before the phase of full flowering of plants the level of N2 assimilation by adding 0.25 g of carmoisine to the vermiculite preparation was at the level of the control plants. During the period of full flowering, this figure exceeded the indicators of control plants by 7.6 and 18.8% with the introduction of 0.25 and 0.5 g of the colorant.\u0000Conclusions. Carmoisine can be applied in the further study of the effectiveness of its use as a dye identifier for controlling the uniformity of marking of loose bacterial preparations on seeds by adding 0.25 and 0.5 g per 200 g of a biopreparation, since this did not show a negative impact on the formation and functioning of the soybean – Bradyrhizobium japonicum symbiotic systems.","PeriodicalId":53379,"journal":{"name":"Plant Varieties Studying and Protection","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47935034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jute mallow (Corchorus olitorius L.) is a mucilaginous vegetable and fiber crop cultivated in the tropics, where catnip (Nepeta cataria L.) and Mexican sunflower (Tithonia diversifolia L.) are common weeds. Hence, the study investigated the growth, yield, and nutrient level of jute mallow in weed-free, catnip, and Mexican sunflower environments.\u0000Methods. The study involved two screen-house experiments in a Completely Randomized Design (CRD) with six replications. The treatments were 0 (control), 2, 4, 6, 8, and 10 weed plants per pot in both experiments. These are 0, 100, 200, 300, 400, and 500 weed count per square meter equivalent, based on the surface area of the pots used. Mexican sunflower and catnip plants interacted with jute plants in the first and second experiments, respectively. Growth parameters of jute mallow were recorded weekly from 5 to 8 weeks after sowing (WAS), and harvesting was done at 8 WAS. The proximate composition of jute was evaluated using standard procedures outlined by AOAC. The data collected were subjected to analysis of variance (ANOVA), and means were separated using Duncan Multiple Range Test (DMRT) at P < 0.05.\u0000Results. Catnip and Mexican sunflower negatively impacted the morphological features of jute mallow from 100 plants per square meter upwards. Catnip and Mexican sunflower, at 300 and 100–500 plants per square meter, respectively, reduced the dry weight of jute mallow. The crude protein content of jute mallow was also lessened by Mexican sunflower at some point.\u0000Conclusions. The study recommends that the density of catnip and Mexican sunflower plants interacting with jute mallow should be maintained below 100 plants per square meter to prevent yield loss.","PeriodicalId":53379,"journal":{"name":"Plant Varieties Studying and Protection","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41501513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to visual observations in periods with low moisture supply, leaf turgor did not decrease, so in the field, drought resistance of hybrid tea roses was estimated at 5 points on a 6-point scale. In the laboratory, water deficiency in the leaves was calculated (as a percentage of the total water content in the state of full saturation). According to the indicators of the water-holding capacity of leaf tissues, varieties with the level of moisture loss in the exposure after 12 hours from the lowest to the highest, were selected.\u0000Conclusions. All varieties of hybrid tea roses from the collection of M. M. Gryshko NBG of NAS of Ukraine, included in the experiment, in field conditions were rather drought-resistant. According to the indicators of drought resistance of leaves from 44 model varieties, 9 with low (up to 22.30%), 5 with medium (up to 24.37%), 30 with high and very high level of moisture loss were identified (27.23–46.47%).

Variety ‘Vik 2020’ was obtained as a result of creation of artificial populations. The plants are characterized by higher content of cannabigerol (1.034 ± 0.0323%), and almost zero of other secondary metabolites, such as cannabidivarin, cannabidiol, cannabichromene and psychotropic tetrahydrocannabinol (0.003 ± 0.0011; 0.018 ± 0.0080; 0.012 ± 0.0027, and 0.005 ± 0.0012%, respectively). The t rait of cannabigerol content is quite stable within the population and is not correlated with the trait of tetrahydrocannabinol content (r = -0.23). TLC showed that cannabigerol accumulated mainly in the form of cannabigerolic acid and to a lesser extent as a neutral compound, which is consistent with the theory that this substance is a precursor for the synthesis of other cannabinoids. According to the results of the competitive variety test, when growing to obtain fibre and seeds, the variety features short height, specifically significantly lower total (206.4 cm) and technical stem length (135.6 cm) compared to the standard variety, significantly higher inflorescence length (70.8 cm), which determine the formation of the significant yield of biomass suitable for pharmaceutical use and high seed yield (0.98 t/ha). The yield of total fibre was the same as in the standard variety (29.0%), but its quality and technological value for primary processing were higher.

A notable feature of the variety is the formation of friendly seedlings and intensive plant growth at the beginning of the growing season, which helps to reduce the weediness of crops. \u0000Conclusions. The new variety of hemp ‘Artemida’ of multiple purposes belongs to the Central European ecological and geographical type, although created as a result of varietal-linear hybridization of different types with selection on the basis of productivity, is characte­rized by complete absence of cannabinoid compounds, high oil content and fiber quality. The variety is recommended for growing for fiber and seeds. Due to its high yield potential, it is competitive in the industrial hemp market.","PeriodicalId":53379,"journal":{"name":"Plant Varieties Studying and Protection","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43434562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
