Abstract:The effects of boron deficiency and toxicity on the morphology and foliar generalities of mung bean (Phaseolu s aureus Roxb) were investigated in hydroponic culture. Reduced biomass produ ction in response to limited supply of boron was accompanied by an increased sho ot to root ratio. Foliar generalities were also altered by boron deficiency: lea f expansion was inhibited together with specific leaf area (SLA), implying t hat there was a high leaf cell density due to restricted cell expansion. An incr ea...
