Bitter Vetch

Alkalinity is one of the main limiting factors of seed germination in alkaline soils. The aim of this study was to evaluate the effects of Na2CO3 levels (0, 5, 10, 15, 20 and 25 mM) on seed germination, seed reserve utilization and seedling vigour of three local bitter vetch cultivars (Buinzahra, Shahreza and Tarom). The results indicated that increasing Na2CO3 concentrations caused a decrease in germination percentage (GP), germination rate (GR), seedling length, seedling dry weight (SLDW) and seed reserve utilization efficiency (SRUE). The rate of reduction in shoot length in comparison with the control in different concentrations of Na2CO3 was detected from Buinzahra as 30-92%, Shahreza 39-97% and Tarom 13-83%. Decrease in root length was more than shoot length in all the cultivars at each Na2CO3 level, as compared to the control. The weight of mobilized seed reserve (WMSR) and seed reserve depletion percentage (SRDP) decreased with increasing Na2CO3 levels up to 10 mM in Buinzahra and Tarom cultivars and up to 15 mM in Shahreza. WMSR and SRDP then rapidly raised with higher alkalinity levels. These results suggest that reduction of seed germination and decline in seedling dry weight in response to alkalinity stress is a consequence of decline in seed reserve utilization efficiency.

By means of microscopic analyses, it was shown that root nodules formed by <em>Chamaecytisus podolicus</em> exhibited all structural features typical for indeterminate nodules of temperate genistean shrubs: (<em><strong>i</strong></em>) apical nodule meristem composed of infected and non-infected domains, (<em><strong>ii</strong></em>) parenchymatous bacteroid-containing tissue with infected cells only resulting from mitotic activity of infected meristematic cells, (<em><strong>iii</strong></em>) absence of infection threads, and (<em><strong>iv</strong></em>) convoluted bacteroids singly enclosed in a symbiosome membrane. For the first time, it was shown that the nodule meristem is organized into longitudinal files of sister cells.

Currently, a real challenge for the workers in the agricultural research field is to stop or reduce the use of expensive agrochemicals/ chemical fertilizers which are hazardous to the environment as well as human health. Present study was aimed to improve the growth and obtain optimum yield of Vigna crop with eco-friendly, non-toxic way and to reduce the use of agrochemical/chemical fertilizer application in agricultural activities. A pot experiment was conducted to study the effect of chemical fertilizer (DAP) and biofertilizer ( Rhizobium strain) separately and in combination on seed germination and seedling growth (at 30 days) based on morphological parameters such as seedling length (cm), fresh weight (g), dry weight (g) and leaf area (cm)2 of Vigna radiata (L.) Wilczek. After one month (30 Days) observations, it was found that seedling length, fresh and dry weights and leaf area were maximum in T4 and minimum in T15, T7 and T8 favored improved seedling length and leaf area whereas T7, T8, and T9 favored improved fresh and dry weights as compared to control.
