Brassica Napus L

Stage of maturity at harvest is one of the most important factors that can influence the quality of seeds. This research was carried out in 2008- 2009 to evaluate the development of physiological seed quality in three winter oilseed rape (Brassica napus L.) cultivars (Modena, Opera and SLM046). Seeds were harvested serially in 9-10 stages during their development and maturation. Maximum seed weight (mass maturity) was achieved at 48-54 days after flowering, when seed moisture content was 41-50%. However, maximum seed quality as measured by seed viability, germination percentage, germination rate and seedling dry weight was obtained 10 to 22 days after mass maturity. Thereafter, seed quality of all cultivars was started to decrease, due to ageing. Maximum germination rate of SLM046 and maximum seedling dry weight of Opera were significantly higher than those of other two cultivars. These variations in seed quality parameters were attributed to differences in genetic constitution among oilseed rape cultivars. It was concluded that high quality seeds of winter oilseed rape cultivars could be produced with 14-16% moisture content, which is suitable for direct and mechanical harvesting, threshing and storage without further drying.

Chickpea Cultivars

AbstractA split plot experiment (using RCB design) with three replications was conducted in 2012 and seed physiological quality of three chickpea (Cicer arietinumL.) cultivars (Azad, Arman and Jame) was evaluated at seven stages under well and limited irrigation conditions. Maximum seed weight (mass maturity) was achieved at 40–45 days after flowering. However, maximum seed quality was obtained 7 to 10 days after mass maturity, depending on irrigation intervals and cultivars. At earlier harvests, because of immaturity, and at later harvests, due to ageing, seed quality was low. Seed filling rate and maximum seed weight of chickpea decreased with decreasing water supply, but water deficit had no significant effects on seed quality as measured by germination percentage, germination rate and seedling dry weight. Significant differences in seedling dry weight among chickpea cultivars were attributed to significant variation in seed weight affected by genetic constitution.

Laboratory tests were carried out to study the effect of different fungicides i.e. Bavistin DF, Vitavax and Genuine 50WP on the seed quality of lentil during storage condition. After processing and drying, seeds were preserved separately with three fungicides at the rate of 2.5g kg-1 of seeds and stored in earthen pots till next planting time. The seed quality i.e. moisture content (%), germination rate (%), dry weight (g) of seedlings and vigour index were measured at the end of storage period. The average germination percentage of the initial seed lot was 90% and moisture content was 9%. Among the three fungicides, Bavistin DF showed higher values for germination percentage (91.3% in 2004 and 92.7% in 2005), dry weight (0.70 g in 2004 and 0.67 g in 2005) and vigour (63.8 in 2004 and 62.1 in 2005).Jahangirnagar University J.
