Abstract
BHC supplied to seedlings of Sorghum bicolor grown in nutrient solutions enhanced growth at intermediate concentrations and inhibited growth at high concentrations. The weights of all plant parts were greatest at intermediate BHC concentrations. Photosynthesis rates were not affected except at the highest BHC concentration, but respiration rates decreased successively as the BHC concentration was increased. The concentrations of chlorophyll a and b decreased with higher BHC levels but were otherwise unaffected. The concentrations of reducing sugars, sucrose and starch generally paralleled the growth pattern responses to increasing BHC concentrations. Phytotoxicity of BHC to the seedlings was from inhibition of respiratory processes; growth stimulation was a direct response to BHC independent of benefits of insect control.
