Abstract:
Taking Lysionotus pauiflorus as test material,using the method of setting up the arid environment,variation rules of different drought stress conditions on relative water content,water potential and chlorophyll content of Lysionotus pauiflorus leaf were researched,in order to explore physiological response of Lysionotus pauiflorus under drought stress.The results showed that the relative water content had no significant change at different degrees of drought,the water potential increased first and then decreased after 12 days,and the chlorophyll content sharp decline after 12 days too.The results suggested that the drought had little influence on Lysionotus pauiflorus within 12 days,but the Lysionotus pauiflorus were destructed after 12 days of drought treatment,it should be timely watering of Lysionotus pauiflorus after 12 days of drought in order to avoid injury.
