Abstract
The present experiment designed to evaluate the response growth characteristics of two soybean cultivars (032 and BP) to cold stress (5 °C) at two light intensity levels [normal (8000 lux) or low light (2000 lux) intensity]. Treatments were arranged in a factorial experiment based completely randomized design with three replicates under controlled conditions. The results showed that root volume and nodule number of root in soybean seedlings significantly decreased (38 and 32 %, respectively) when grown at cold stress as compared to those grown under control conditions. Cold stress, also, reduced leaf and root fresh and dry weights and shoot dry weight in both light intensities, however, this effect was more noticeable at low light intensity for root dry weight (53%) and at normal light intensity for leaf and shoot fresh and dry weights (47% ). Cold stress, also, significantly suppressed stem fresh weight in both cultivars (34% in 032 and 27% in BP). BP cultivar when grown at 8000 lux had nearly 16% lower leaf dry weight than plants grown at, 2000 lux. However, 032 cultivar in normal light intensity showed no significant response in growth parameters to low light intensity. In both light intensities, cold stress significantly reduced the root fresh and dry weights. Although two soybean cultivars showed slightly contrast behaviors, the rate of cold stress damages decreased when soybean plants grown under lower light intensity.
