Abstract
Investigations were carried out on leaf expansion, photosynthesis, transpiration, Leaf diffusive resistances and leaf water potentials of water stressed plants of Amaranthus lividus and Gynandropsis gander raised in. plastic pots containing garden soil. Severe desiccation reduced the rates of leaf expansion, photosynthesis and transpiration. In short-term experiments, soil water stress suppressed the rates of photosynthesis more drastically than The rates of transpiration. When desiccated plants of A. lividus and G. gyandra were rewatered recovery of leaf water potentials to the predesiccation levels was incomplete after a period of 18 h. However, in G. gyandra. leaf diffusive resistances returned to the predesiccation level under the same conditions.
