The aim of the experiment was to investigate the impact of innovative organic fertilizers: BioIlsa, BioFeed Ecomix, biostimulator Ausma and mycorrhizal inoculum Mykoflor on the fine roots growth characteristics of ‘Vanda’ sweet cherry trees in comparison with NPK mineral fertilization. The experiment involved five combinations, in three repetitions of three trees each, treated with tested preparations. The study assessed the influence of fertilization on the lifespan of the roots, the depth of their formation, their diameter and survivorship using minirhizotron camera. The highest numbers of roots were found in the treatment where the plants were fertilized with NPK and the lowest following the use of the biofertilizer BioFeed Ecomix. The longest lifespan was shown by the roots of the trees treated with BioFeed Ecomix – 347 days, and the shortest – by those fertilized with the Ausma – 225 days. The lifespan of the roots increased with their diameter. The roots that lived the longest had a diameter in the range from 0.9 to 1.0 mm – 568 days, and the shortest-living were the roots with a diameter smaller than 0.3 mm – 238 days. The roots that formed in late autumn and winter had the shortest median lifespan of 159 days, while the roots formed in the spring where characterized by the longest lifespan of 300 days. The lifespan of the roots formed close to the soil surface was the shortest – 225 days, while that of the roots formed at a depth of 10 to 20 cm was the longest – 326 days. Biological origin, organic nitrogen rich fertilizers positively influence on fine roots lifespan and longevity. Mineral fertilization increases number of new formed roots.","PeriodicalId":13110,"journal":{"name":"Horticultural Science","volume":"48 1","pages":"105-116"},"PeriodicalIF":1.2,"publicationDate":"2021-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47303204","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}

We used a fully randomised experimental block design with factorial arrangement of 2 × 4 (grafted and ungrafted plants and four ratios of NO3–/NH4+), on eight treatments in total with four replicates each, using Tukey’s mean comparison test (P ≤ 0.05). The rootstock was ‘Silex’ by Fito Seeds, with the ‘El Arrojado’ graft (variety) by Gene Seeds. The graft produced an increase in growth, dry biomass production, stomatal density, trichome number, epidermal cell density, fruits per plant, average fruit weight, fruit size and total soluble solids, in comparison with the ungrafted tomato plants. In most of the assessed variables, the grafted tomato plants gave their best response at an 85/15% NO3–/NH4+ ratio; while the ungrafted plants performed better at a 92/8% NO3–/NH4+ ratio. The response of the grafted plants to the different NO3–/NH4+ ratios suggests that grafting induces tolerance to NH4+.","PeriodicalId":13110,"journal":{"name":"Horticultural Science","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2021-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44584260","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}

However, the underlying mechanisms are poorly understood. In this study, we used two tomato lines 081018 (K+-deficiency-sensitive) and 081034 (K+-deficiency-tolerant), showing tolerance to K+ deficiency to investigate the relationship between the H2O2 and sucrose in the tomato under K +-deficiency. The H2O2 accumulation was increased by the low K+ condition (0.5 mM) after 8 h in 081018. The enzymes related to the metabolism of H2O2 were decreased, and more malondialdehyde (MDA) was produced. After 24 h, the sucrose content had accumulated significantly in the leaves, however, it was deficient in the roots, and the expression level of the sucrose transporters (SUT1) was inhibited. In 081034, the activity of antioxidant enzymes was increased under K+-deficiency, and then the H2O2 subsequently returned to the control treatment (4 mM) levels and did not produce more MDA. The sucrose content was not significantly different from the control treatment after 24 h. The expression of SUT1 was not suppressed. These results suggested that the H2O2 dynamics played different roles in the two different strains. The transportation of sucrose was suppressed by the H2O2 from the leaf (source) to the root (sink) in 081018, and unrestricted by the advantageous reactive oxygen species dynamics capacity in 081034.","PeriodicalId":13110,"journal":{"name":"Horticultural Science","volume":"48 1","pages":"90-97"},"PeriodicalIF":1.2,"publicationDate":"2021-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42939604","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}

M9T337, an excellent apple rootstock widely used in commercial orchards, could confer dwarf tree architectures, early fruiting and suitability for high-density planting. However, the rooting ability of M9T3337 is low when it is vegetatively propagated, and researchers have not yet established an efficient micropropagation system. The present study systematically evaluated the multiplication in adventitious shoots and the in vitro formation of adventitious roots to determine the effects of the culture media and plant growth regulators of M9T337 and a rapid micropropagation system was developed. For the shoot multiplication, the highest multiplication index of 3.93 was obtained on Murashige and Skoog (MS) media supplemented with 2.0 mg/L 6-BA, 0.1 mg/L NAA and 0.3 mg/L GA3 from 12 combinations of 6-BA and NAA. Stronger and taller adventitious shoots were grown on MS supplemented with 1.8 mg/L 6-BA and 0.5 mg/L NAA. The optimal media with 100% rooting was obtained using 1/2 MS supplemented with 0.3 mg/L IBA or MS supplemented with 0.6 mg/L IBA for the rooting induction, resulting in mean rooting numbers of 13.00 and 11.33, respectively. Additionally, the effect on rooting of adding 0.3 mg/L IBA or not on the 1/2 MS and MS media was compared; the results suggested that an appropriate IBA concentration was the key to successful rooting. The rooted plantlets were acclimatised in a shaded greenhouse with an 84% survival rate. The established micropropagation system could be used for the rapid propagation of M9T337 for commercial production.","PeriodicalId":13110,"journal":{"name":"Horticultural Science","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2021-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48126613","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}

This experiment compared the effect of the mineral stimulator Tytanit® and the biological preparation Effective Microorganisms (EM) on the physiological and biochemical activity, as well as the yield of the common bean (Phaseolus vulgaris L.). The photosynthetic pigments, free proline and malondialdehyde were assayed and compared at three phenological phases of the bean: 15 BBCH, 24 BBCH, 65 BBCH. The yield parameters included the average number of pods per plant, as well as their fresh and dry mass. Additionally, the nutrient content in the pods was determined according to the atomic absorption spectrometry method. The study revealed a positive effect of both preparations on increasing the content of chlorophyll a, b, and the carotenoids in the bean leaves. Plants treated with Tytanit® were characterised by the highest content of malondialdehyde and proline, while EM maintained the aldehyde content on a similar level compared to the untreated plants and significantly reduced the proline content. Both preparations significantly decreased the Mn, Mg, P, and Ca content in the pods and did not have a substantial impact on the yield.","PeriodicalId":13110,"journal":{"name":"Horticultural Science","volume":"48 1","pages":"98-104"},"PeriodicalIF":1.2,"publicationDate":"2021-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49531403","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}

The trees were planted 5 × 5 m in a randomised complete block design with four replicates, with ten trees in each replicate. In the late spring, two different pruning systems were applied; traditional open centre (OC) and de-branched top trees (DBT). The OC trees were headed at 80 cm above the ground. DBT is a modification of the OC, but no heading was undertaken and the new shoot growth arising from the 20 cm at the top of the plant were removed. Before the winter pruning took place, measurements were taken on the upper two opposite branches. The average length and diameter values of the upper two opposite branches at the top of the trees trained to the OC were higher than those trained with the DBT. In contrast, the distance between the upper two branches (25 cm) at the top of the DBT trees was significantly higher. Likewise, the values of the crotch angles (48°) and the number of branches (81 of 100 branches) that showed desired crotch angles (more than 40°) were remarkably higher in the trees trained with the DBT. After the winter pruning took place, the DBT trees were higher than the OC trees. Additionally, the trees trained with the DBT had low pruning costs and took less time. Moreover, the pruning wood weight of the DBT trees was about half of the pruning wood weight of the OC trees. In conclusion, the DBT training system showed the desired impact on the crotch angles and the tested pruning characteristics.","PeriodicalId":13110,"journal":{"name":"Horticultural Science","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43754023","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}
