Abstract:: In southwest Karst region, physiological indicators of Broussonetia papyrifera seedlings to different soil water conditions were measured by means of soil drought stress, its physiological responses to soil drought stress were studied. The results showed with the aggravation of soil drought stress, leaf water potential, net photosynthesis rate, transpiration, stomata conductance and WUE(water using efficiency) of Broussonetia papyrifera seedlings decreased, which indicatd Broussonetia papyrifera had high drought-tolerant potential productivity and strong adaptability to water deficiency in Karst forest. These illustrated the physiological basis that Broussonetia papyrifera can survive in degraded karst habitat.
