Abstract

Utilizing an integrated soil moisture stress approach two different experiments were conducted simultaneously to investigate the effects of water stress on growth and related physiological characteristics of ((Averrhoa carambola)). The first experiment clearly indicated a high correlation between soil water availability and a reduction in plant vegetative growth. In the second experiment there was a significant correlation between leaf water potential and a reduction in stomatal conductance transpiration rate and photosynthesis rate. The inhibition of photosynthesis rate was only apparent when leaf water potential was reduced to -0.85 MPa. However chlorophyll content was only affected by a further reduction in water availability. The relationship between physiological characteristics and vegetative growth is discussed
