The Influence of Seed Production Environment on Seed Development and Quality of Soybean (Glycine max (L.) Merrill)

The aim of the study was to determine effect seed production environment in Sri Lanka on development, maturation, and subsequent quality. experiment conducted at six environments, three locations (Mahailluppalama (M1), Polonnaruwa (POL), Aluttarama (ALU), over two planting cycles (P1, P2). Seed development seedling quality characteristics were evaluated five reproductive (R6, R7, R8, R8 + 5 10) maturity stages. infers that late (LR) stage (R6–R8) critical determining If LR coincided with cumulative rainfall (RF) 100 mm or above 75% relative humidity (RH), categorized as wet environment, around 27.5 days required for completion maturation compared only 17.5 dry environment. lots from during surpassed minimum standards (75% final germination, germination index 300, rate 25% per day, vigor 2500 15 µmol/min/mg FW catalase activity) R7 onwards, while this occurred A significant negative correlation (r = −0.50 **) observed between glucose content, antioxidant enzyme activities percentage. In conclusion, findings provide useful information expansion areas Lanka.
