Proline is an amino acid closely associated with plant responses to environmental constraints. This research aims to study the response of four varieties of durum wheat (Triticum durum) subjected to water stress stimulated by polyethylene glycol (20% PEG-6000) which is equivalent to osmotic potential of -1.2 Mpa. A total of 4 wheat genotypes were grown hydroponically and four treatments were imposed. Wheat plants exposed to drought stress showed reduced growth, which was correlated with reduced relative water content, chlorophyll content and stomatal conductance as evidenced by principle component analysis (PCA). It also revealed that electrolyte leakage and malondialdehyde (MDA) accumulations were closely related with the declined growth and wheat plants development under drought stress. Importantly, application of 6 mM of exogenous proline improved the growth responses of wheat plants to drought stress. Proline strengthened numerous physio-biochemical processes coupled with decreasing in MDA levels which indicates successful adaptation of wheat plants to drought stress. The results of PCA strongly supported that application of proline in stressful conditions ameliorated the responses of wheat mostly by enhancing physiological and biochemical activities. Eventually, it can be concluded that proline supplementation is one of the useful approaches to alleviate the adverse effects of water stress on wheat crop.","PeriodicalId":49589,"journal":{"name":"Romanian Agricultural Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71121891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The required new varieties have been improved by effective breeding programs for hay production and rangeland revegetation in arid and semi-arid conditions. The objectives of this study were to identify the agro-morphological and quality traits of the three advanced populations and the control population in crested wheatgrass. The advanced population G-465 was 7.68 and 1.92 t ha-1 in overall averages of fresh forage and hay yields, respectively. According to these values, it is seen that the G-465 advanced population is 5.93, and 6.07% higher than the control population in terms of both fresh forage and hay yields, respectively. Besides, no significant differences seemed among the study populations in crude protein content and relative feed value in 2015 and two-year averages. Consequently, the G-465 advanced population was good performance under semiarid conditions and it is advisable for similar circumstances. For identifying yield-related traits, correlation analysis was performed and high correlation coefficients occurred between fresh forage yield with stem diameter (0.474**), internode length (0.469**), flag leaf length (0.761**), and flag leaf width (0.711**). In light of these data, these traits should be taken into account in the selection of phenotypic plants.

The researches were performed during two particularly dry years in two experimental plots located in Valea Cǎlugǎrescǎ viticultural center. In one of them were experimented, as soil maintenance systems, the total straw mulching and the partial mulching (interval between rows) with marc compost, in the other the artificial grassing of the interval between rows with ornamental clover Nano and with honey plants represented by Melilotus officinalis. The experimental data have shown the positive effect of mulching systems on soil microbial activity, highlighted by an increase of soil microbial load and of its diversity (represented by bacteria, fungi, algae and protozoa), especially in case of mulching with marc compost (15.94 million microorganisms/g of soil, as compared with 5.9 million in case of black furrow system). Also, the ratio between fungi and bacteria was higher in case of partial mulching, this aspect being a favorable factor for soil biological activity. The use of cover crops indicated a positive effect in the increasing of useful entomofauna, belonging to the orders Ortoptera, Coleoptera and Arahnidae (especially in case of the artificial grassing).","PeriodicalId":49589,"journal":{"name":"Romanian Agricultural Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71122524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such an alternative would be the use of phytochemical compounds, with an antioxidant role, found in fenugreek seeds. This research paper aimed to evaluate the effect of three types of extracts obtained from fenugreek seeds (Trigonella foenum-graecum) on radish seeds through the germination bioassay. The extracts were obtained in three different organic solvents (ethanol 70%, propylene glycol - PG-50% and ethanol 40%), the phenolic profile was analyzed using the Folin Ciocalteu method and the antioxidant activity by the DPPH bioassay. The results showed that the variant in 40% ethanol was superior regarding the content of total polyphenols (TPC) and flavonoids (TFC) (2.667 CAE mg/ml and 3.199 RE mg/ml) compared to the extract variants obtained in 70% ethanol (1.635 CAE mg/ml and 1.863 RE mg/ml) and PG 50% (2.072 CAE mg/ml and 2.147 RE mg/ml), what particularly influenced the antioxidant activity. The Fenugreek extract in ethanol 40% has a higher redox potential compared to the other extract variants tested in our study. The phytotoxic profile of the extracts was achieved by applying the radish (Raphanus sativus) seed germination bioassay. According to the results obtained, the extracts in 40% ethanol showed moderately phytotoxic activity at the concentrations of 0.50% and 1.0% and strongly phytotoxic at the concentration of 1.5% extract, while the extract variant in 70% ethanol, showed moderately phytotoxic activity at the first three concentrations tested and a strong phytotoxic effect at the concentration of 1.5%; in the case of the extract obtained in PG, no phytotoxic activity was recorded on the tested seeds, the Gi being >80%.","PeriodicalId":49589,"journal":{"name":"Romanian Agricultural Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71123040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to effectively exploit these genes in cultivated genotypes, researchers need more information regarding the quantity and distribution of the genetic variability available within the wild sunflower species, which can offer a multitudine of valuable traits for traditional or molecular breeding. This study was conducted to reveal the genetic diversity of wild and cultivated sunflower genotypes using ISSR markers. From a total of 19 ISSR markers, which were used to evaluate the genetic diversity, eight markers (UBC808, UBC823, UBC834, UBC836, UBC840, UBC845, UBC853, 17899A) clearly differentiated the wild sunflower genotypes from the wild sunflower and/or the cultivated sunflower. The primers amplified a total of 120 alleles ranging from 10 to 22 alleles per marker. A wide range of fragment length was detected among the accessions, from 140 to over 1500 bp. The neighbor-joining dendrogram, based on Rogers genetic distance, of the genotypes studied consisted of two main clusters of different sizes: five entries were grouped into cluster A and the remaining six entries were grouped into cluster B. It is interesting that genotypes of Helianthus anuus L., Helianthus maximiliani and Helianthus argophyllus were clustered together. Another aspect observed, refers to interspecific variability for Helianthus debilis genotypes. Regarding the PCA, the first two principal axes accounted for 26.8% (CP1) and 16.1% (CP2) of the total variation, respectively, together explaining 42.9% of the total variability. In the future, this molecular genetic information can be combined with morphological and biochemical data to improve the sunflower breeding program.","PeriodicalId":49589,"journal":{"name":"Romanian Agricultural Research","volume":"3 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71121212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides, they are named as quite sensitive to salt stress. Salinity is one of the utmost abiotic stress factors limiting agricultural production, which affects plant growth and development at different levels. Lately, exogenous applications of signalling and/or protective molecules to various parts of plants are used to combat salt stress before or at the time of stress. In this context, this research was conducted to assess the influence of foliar-applied ascorbic acid (AsA) on electrolyte leakage (EL), activity of antioxidative enzymes, total protein (TSP) content and protein profiles in the two common bean genotypes (salt-sensitive “Local Genotype” and salt-tolerant “Şeker Fasulye”) at early growth stage under salinity (0, 50, 100, 150 mM NaCl). The genotypes were exposed to salt stress from fully developed true leaf at the third nodes emerged stage for two weeks, meanwhile 3 mM AsA was foliar-applied every three days. Salt stress increased EL in both genotypes and exogenous AsA application decreased EL value especially in “Local Genotype”. Foliar-applied AsA generally reduced the adverse effects of NaCl on AsA content of both genotypes. Exogenous AsA application also increased the activities of catalase (CAT), ascorbate peroxidase (APX) and glutathione reductase (GR) in the salt-stressed common bean plants and did not play a role in the TSP content. However, it has been determined that SDS-PAGE protein profiles represent adaptive mechanisms for dealing with excess salt in common bean genotypes. The results suggested that foliar-applied AsA was effective in reducing the adverse effects of salinity especially in relatively salt sensitive common bean genotype.","PeriodicalId":49589,"journal":{"name":"Romanian Agricultural Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71121968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
