摘要
Peanut plants were adapted to drought. Due to parahelionastic leaf movements under water stress they decreased heat load and transpiring area. Folding of leaflets minimised damage to photosynthetic apparatus by high temperature. A positive correlation between transpiration rate (E) and leaf water potential (Psi(W),) indicated the dependence of the latter on E. Phosphoenolpyruvate carboxylase (PEPC) activity progressively increased with increased period of stress, whereas activities of ribulose-1,5-bisphosphate carboxylase (RuBPC) and NADP-glyceraldehyde-3 phosphate dehydrogenase (NADP-G-3-PDH) decreased gradually.
