边坡先锋植物木豆的抗旱性
Drought Resistance Research for Slope Pioneer Plant Cajanus cajan
摘要
Abstract
Objective] To explore the effects of drought stress on photosynthesis,physiological and biochemical indices of Cajanus cajan,and to provide scientific references for species screening and community reconstruction in ecological restoration of hydropower slope.[ Method] Pot wa-ter control method was used for drought stress of C.cajan.Changes of net photosynthetic rate (Pn),stomatal conductance (Gs),transpiration rate (Tr),intercellular CO2 concentration (Ci),water use efficiency (Pn/Tr),malondialdehyde (MDA),proline (Pro) and soluble glucose con-tent were detected in C.cajan.[Result] C.cajan seedlings were greatly affected by the moisture change.Under drought stress,the Pn,Gs,Tr, Ci and Pn/Tr all significantly decreased,showing a negative photosynthetic response to the drought stress.MDA,Pro and soluble glucose content significantly increased,so as to effectively respond to drought stress.[ Conclusion] C.cajan has strong draught tolerance,can adapt to the ecolog-ical environment of dry-heat area.It is the optimal shrub to control degraded mountain land.关键词
