This study was performed in order to evaluate the effects of irrigation and application of Zn fertilizer on  seed storage proteins  in chickpea, Azad cultivar. Experiment was performed in an factorial using randomized complete block design with three replications. In this experiment, two factor consist of irrigation in three levels (I1= non irrigation and I2= irrigation in...

Influences on viability and germination of seeds have been studied intensively for many years, particularly for the numer-ous commercially important agricultural, ornamental, and timber species. High germinating seed lots may differ substantially in field emergence when sown at the same time in the same field, and/or may differ in performance after storage in the same environment or transport t...

Changes in seed dormancy were selected during the domestication of crop plants from wild-plant species, because some features of dormancy that provide ecological advantages presented agronomic disadvantages within a farmed system. Seed dormancy varies widely among seed batches, even for seeds of the same genotype, indicating large environmental influences. For genetic studies, it is essential t...

In annual forage legumes such as the common vetch (Vicia sativa L.), in which the pods represent a substantial proportion of the total biomass, the optimum harvesting stage may not adjust to the classical model of decreasing nutritive value after flowering. The effect of harvest time on the yield of the main chemical components of common vetch was evaluated under field conditions typical of the...

Mitochondrial malate dehydrogenase (mMDH; EC 1.1.1.37) has multiple roles; the most commonly described is its catalysis of the interconversion of malate and oxaloacetate in the tricarboxylic acid cycle. The roles of mMDH in Arabidopsis (Arabidopsis thaliana) seed development and germination were investigated in mMDH1 and mMDH2 double knockout plants. A significant proportion of mmdh1mmdh2 seeds...

The critical node (CN) in seed aging in rice (Oryza sativa) is the transformation from Phase I (P-I) to Phase II (P-II) of the reverse S-shaped curve (RS-SC). Although mitochondrial dysfunction plays a key role in seed ageing, the metabolic shift in the CN remains poorly understood. Here, we investigated the mitochondrial regulatory mechanisms during the CN of rice seed ageing. We showed that d...

objective(s):some pathologic situations such as diabetes and metabolic syndrome are associated with alternation in nitric oxide level. incidence of these condition increases with aging. on the other hand, insulin secretion is modulated by nitric oxide, and nitric oxide synthase (nos) activity is also altered in diabetes. in this study, modification in the enzyme activity associated with aging a...

conclusions reported herbal drugs might be beneficial for further studies for the management of skin aging and aging process. results skin aging begins with whole body aging process and entire body gets cold and dry in elderly. wrinkle formation is highly associated with loss of “skin natural moisture”. in the management, specific food supplements, simple massage therapy as well as herbal drugs...
