GLM approach identified association for three traits on chromosome 1, 2, 4, 5, 6, 8, 9, 11 and 12 explaining 16.07% to 38.66% phenotypic variance whereas MLM approach detected association for four traits on chromosome 1, 4, 7, 8 and 11 explaining 15.51% to 27.24%. In GLM approach, the marker loci RM430_200 located on chromosome 5 showed highly significant association with test weight explained maximum phenotypic variance of 38.66%. While in MLM, marker RM320_250 located on chromosome 7 showed highly significant association with grain breadth accounted for 27.24% of phenotypic variance. The significant marker-trait association was lower in MLM compared to those in GLM. MLM method was proven to be useful in controlling false associations. The marker-trait association identified from the present study would be validated and utilized in marker assisted breeding programs of grain shape traits in rice.","PeriodicalId":14689,"journal":{"name":"Israel Journal of Plant Sciences","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46869918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to analyze the effect of MWE on rice yield with different modes of treatment such as seed soaking, root treatment, and foliar spray. Rice seeds were soaked at different concentrations of MWE for 24 h before seeding. Plants grown from rice seeds soaked in 100 g/L MWE produced 6.6 tons/ha yield, whereas, roots of rice seedlings soaked for 4 h in varied MWE concentrations before transplantation and plants treated with 100 g/L MWE produced an yield of 6 tons/ha. In the last group, 45 day old rice plants were subjected to foliar spray with varying concentrations of MWE, where the foliar spray of rice plants with 100 g/L MWE showed a 6.5 tons/ha yield. As plants grown from rice seeds soaked in 100 g/L MWE produced a high yield, the leaves from these plants were analyzed to study the effect of MWE treatment on phenylalanine lyase and hydrogen peroxide (H2O2) and nitric oxide levels and genes involved in rice yield. The leaves of plants grown from rice seeds soaked in 100 g/L MWE showed increased H2O2 and SAM2 gene levels compared to control plants. This study reports the potential role of MWE as an environmentally safe, cost-effective and easy-to-use biostimulant for enhancing yield of rice.","PeriodicalId":14689,"journal":{"name":"Israel Journal of Plant Sciences","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49191308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to quantify the physiological basis of heterosis for seed yield in safflower by examining 19 safflower hybrids and their parents for photosynthetic traits, and yield and its components. The results showed that heterosis for yield and its components was high and positive but was low and negative for photosynthetic traits in most of the hybrids studied. There were weak and non-significant relations between photosynthetic traits and yield and its components. Hybrids were more efficient in translocating photoassimilates to two major sink organs viz., number of seeds and number of capitula despite having low net photosynthesis than parents. Seed yield increase in safflower is more sink-than source-limited and was necessary through heterosis for sink organs. Heterosis breeding for larger sink size with parallel increase in effectiveness of sink organs in translocation of photo-assimilates is suggested for yield improvement in safflower.","PeriodicalId":14689,"journal":{"name":"Israel Journal of Plant Sciences","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43156417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A sum of fifteen quantitative characters were explored and subjected to multivariate analyses. Significant variability was observed across the ber cultivars under study. Pearson’s correlation analysis identified days to first flower initiation, a higher number of flowers per cluster and a higher number of retained fruits per cluster which could be used as the basis of selection for identification of high yielding ber cultivars. The principal component analysis (PCA) estimates 60.2% of the total variability in ber cultivars is contributed by PC1 and PC2. The scatter plot of the first two components highlights the number of retained fruits per cluster, yield per tree, pulp weight, fruit width, stone weight and number of flowers per cluster as principal characters that played a significant role in the total variability. Further, PCA also helped to identify Mehrun, Manuki and Chhuhara as superior ber cultivars which performed well with respect to the PC1 and PC2. The Mahalanobis D2 statistics grouped all the twelve ber cultivars into five clusters indicating the existence of ample genetic diversity among the cultivars. Considering the inter-cluster distance along with cluster mean it could be concluded that the cultivars of cluster II and Cluster III may be utilized to estimate the combining ability for effective exploitation of heterosis or to isolate desirable transgressive segregants.","PeriodicalId":14689,"journal":{"name":"Israel Journal of Plant Sciences","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46755631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The spores’ formation through sexual reproduction in the azolla species is influenced by climatic condition. Keeping this fact in view, the present study was conducted with an aim to study the impact of temperature on the sporocarp formation and also developing storage techniques for sexual propagation in the azolla species. The study showed that the sporulation in Azolla pinnata was more sensitive to increase in the temperature than Azolla microphylla. Azolla pinnata did not sporulate on rising maximum temperature; however sporulation in Azolla microphylla was delayed by one month due to rise in the temperature during second year compared to the first year. Conversion of the freshly collected sporocarps into Azolla microphylla plants were decreased by 4.2–9.3% on increasing minimum and maximum temperatures by 5°C and 8°C, respectively and conversion of the one month old sporocarps into plants was decreased by 1.8–8.7% on rising minimum and maximum temperatures. On storing sporocarps in the refrigerator resulted in higher germination percentage than stored at room temperature. Conversion of freshly collected sporocarps into Azolla plants increased on storage of the sporocarps mixing with soil (1:15) in the refrigerator than at room temperature. Germination of one month old Azolla microphylla sporocarps on storage in refrigerator after mixing with soil decreased during second year compared to first year. Therefore, in a controlled environment, azolla may be encouraged to grow sporocarps for exploiting full potential of azolla for eco-friendly agricultural and livestock management.","PeriodicalId":14689,"journal":{"name":"Israel Journal of Plant Sciences","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43101805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The virus infection causes adverse effects on plant growth, and yield. The present study was carried out to develop plantlets from virus-infected plants using meristematic cultures. Cultures were also raised using nodal explant to figure out culture loss caused by the new strain of Jatropha leaf curl Gujarat virus (JLCuGV). Poor (48.3 ± 15.1 %) shoot bud induction was noted in virus-infected explants on MS medium supplemented with 6-benzylaminopurine (BAP) and Indole-3-acetic acid (IAA). Severe culture loss was noted upon subsequent sub-cultures of nodal explants. Apical meristem (MC) developed the highest (86.3 ± 12.5 %) shoot bud induction on Murashige and Skoog (MS) medium supplemented with 0.5 mg/L Thidiazuron (TDZ). Best results in shoot proliferation and elongation were achieved on 1.0 mg/L BAP, 1.5 mg/L IAA and 0.5 mg/L Gibberellic acid (GA3) containing medium with 9.9 ± 1.7 number of shoot buds of 5.2 ± 0.5 cm shoot length. It was interesting to note that the rooting percentage was not affected by virus infection. Shoots obtained from virus-infected and meristem cultures rooted well without any significant difference in rooting percentage. It was known by the study that the generation of planting material from virus-infected plants was possible with meristem explants but recalcitrant with nodal explants.","PeriodicalId":14689,"journal":{"name":"Israel Journal of Plant Sciences","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46893952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim was to evaluate physiological responses of Cd in Alternanthera tenella plants in micro-controlled conditions and to assess the its tolerance level and bioindicator potential. Nodal segments of A. tenella were grown in flasks containing semi-solid MS medium supplemented with (0, 50, 100, and 150 μM Cd). The total fresh and dry weight of the plants, in addition to physiological analyses, were determined after 30 days of cultivation. Plants submitted to Cd showed a reduction in biomass and photosynthetic pigments content. The decline in the Chl a/b ratio indicated the deleterious effects of Cd, as evidenced by the decrease in the density of active reaction centers (RC/CSM). The levels of deterioration in the functionality or structural integrity of the thylakoid membranes (WL) and the activity of the oxygen evolution complex (WK) increased as a function of Cd concentrations. The decreases in photochemical and non-photochemical quenching (qP and qN, respectively) observed in plants exposed to Cd indicated photochemical dysfunctions. Additionally, the increase in the quantum yield of non-regulated energy dissipation (ΦNO) indicated the presence of photodamage. Plants had a low/intermediate TI level (≥21.7) in the analyzed concentration range. A. tenella plants can bioaccumulate high amounts of Cd. The level of physiological responses of A. tenella is dependent on the concentration of Cd, which makes the use of this species even more promising as a bioindicator for this metal.","PeriodicalId":14689,"journal":{"name":"Israel Journal of Plant Sciences","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48673141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
