This study highlighted the negative impact of Zn toxicity on the growth of Trigonella foenum-graecum and the role of ammonium sulphate (AMS) to ameliorate the induced oxidative stress. Growth parameters of seedlings as well as mitotic behaviour of root tip cells were monitored. Under Zn stress, a remarkable growth suppression of seedlings including low rate of germination, reduced root lengths, decreased fresh and dry matters were recorded. At the same time, high protein contents, high malondialdehyde (MDA), H2O2 levels and induced peroxidase (POD) and catalase (CAT) activities were recorded in Zn-stressed seedlings. Meanwhile, the seedlings treated with AMS and Zn/AMS were more or less similar to the control treatment. On the other side, the mitotic index (MI) of Zn-treated root tip cells showed significantly lowered values. The microscopic studies of Zn-stressed root tip cells showed several kinds of aberrations including sticky and lagging, fragmentation, multipolarity and formation of single and multi-chromatid bridges, which affected negatively on mitotic behaviour of root tip cells and overall growth of roots. These mitotic abnormalities were not detected in root tip cells treated with AMS and Zn/AMS. This study indicated that growth retardation and mitotic abnormalities of fenugreek resulted from Zn stress can be ameliorated by the application of AMS. AMS could work against Zn toxicity through supplying the plants with ammonium required for protein synthesis working in Zn detoxification.","PeriodicalId":231568,"journal":{"name":"Journal of Functional and Environmental Botany","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125281313","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}

Millets once the staple food for poor rural people, are now being steadily replaced by wheat and rice. Finger Millet contains highest levels of calcium among cereals. It is also a good source of iron, phosphorus and the amino acid- methionine. The present study was undertaken to develop nutritious and instant baby food from light and dark coloured (PRM 9802 and Pant madua 3) varieties of finger millet using different processing techniques i.e., roasting and malting. The baby food was prepared from the combination of finger millet (roasted/malted), roasted wheat flour, roasted green gram flour and skimmed milk powder in 30:30:25:15 ratios. The baby food prepared from finger millet after roasting exhibited higher content of protein, calcium and iron but low in vitro protein digestibility as compared to malted finger millet. Viscosity of malted weaning gruel was lower than roasted for both the varieties. Sensory quality of weaning gruel was not significantly affected by processing techniques but there was significant difference for acceptability between varieties. While weaning laddoo showed significant difference for acceptability only between two varieties.","PeriodicalId":231568,"journal":{"name":"Journal of Functional and Environmental Botany","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116227075","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}

Six genotypes of five wild relatives of tomato were employed and observations were recorded on qualitative morphological characters such as growth habit, stem pigmentation, twig pigmentation, leaf type, leaf shape, leaf colour, leaf pubescence, inflorescence type, flower size, flower colour, style position, fruit shape, blossom end shape and ripe fruit colour. All the six Solanum species were indeterminate in growth habit. Visible anthocyanin pigmentation in the stem and twig was found in S. chilense, S. cheesmani and S. lycopersicum var. cerasiformae although anthocyanin pigmentation was not visible on the fruit. Inflorescence type was monopartite for all the Solanum species under study excepting S. peruvianum in which it is bipartite in nature. Leaf and inflorescence characters indicated that S. peruvianum was distinctly different than the other Solanum species employed in the present investigation. Style position was inserted inside the anther cone in S. pimpinellifolium and S. lycopersicum var. cerasiformae while it was found exserted beyond the anther cone in other three wild relatives, namely, S. chilense, S. cheesmaniae and S. peruvianum. Ripe fruits of S. cheesmaniae were orange-red and those of S. chilense were yellow while the fruits of S. peruvianum remained light green in colour upon ripening.","PeriodicalId":231568,"journal":{"name":"Journal of Functional and Environmental Botany","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128615053","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}

Enhanced uptake of silica in known to alleviate drought effects but only a small fraction, in the form of ortho-silicic acid (OSA) [Si(OH)4] is soluble and available in soils. Since, the mechanism in Si-alleviated damage caused by drought stress remains unclear; the present study was carried out to assess the efficacy of foliar sprays with OSA in alleviating drought in wheat. Foliar sprays with various concentrations OSA viz., 0, 8, 16, 32 ppm were used at different plant growth stages such as vegetative, booting and seed development stage. Drought was imposed by withhold normal irrigation from crop booting stage to physiological maturity. Foliar application of 32 ppm of Si showed an impact in terms of increase in relative water content, leaf chlorophyll content and lower canopy temperatures. Root growth and root length density were increased under with 32 ppm foliar application with Si. K and P content in straw and seed of wheat were increased with foliar application of Si and a strong (r=0.93) relationship in-between K content in straw and seed was observed under drought conditions. The yield in terms of seed weight got increased with OSA concentrations under drought conditions. The percent of increase was an average of 10% over control under stress condition. Therefore, OSA had strong impact on alleviating drought and minimized the yield losses in wheat under drought conditions.","PeriodicalId":231568,"journal":{"name":"Journal of Functional and Environmental Botany","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115410739","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}

Don contains about 130 indole terpenoid alkaloids including vincristine and vinblastine, which are antineoplastic drugs produced in a very minute quantity in periwinkle leaves. Researchers have been finding ways to enhance the production of these valuable alkaloids. A pot experiment was conducted on periwinkle to explore the effect of single and combined application of irradiated sodium alginate (ISA) and methyl jasmonate (MeJA) on growth, physiological attributes and alkaloids production (vincristine and vinblastine) at 6 and 9 month after plantation (MAP). Foliar application of ISA at 80 mg L−1 improved the growth and other physiological parameters, whereas MeJA at 40 mg L−1 enhanced the content and yield of anticancer alkaloids (vincristine and vinblastine). As compared with the control, their combined application (80 mg L−1 of ISA and 40 mg L−1 of MeJA) increased the total alkaloids content by 33.8 and 36.6% and the total alkaloids yield by 47.7 and 58.0% at 6 and 9 MAP, respectively. Combined application increased the vincristine content by 46.7 and 42.8% and vincristine yield by 59.8 and 66.0% at 6 and 9 MAP, respectively. Similarly, it increased the vinblastine content by 24.6 and 21.0% and the vinblastine yield by 35.3 and 40% at 6 and 9 MAP, respectively.
