Abstract:
Taking cut chrysanthemum ‘Huangzhonghuang’ as test material,controlling water quantity of drought stress for the first 20 days of drought treatment,then normal watering management,15 days later for stress treatment  20 days  again determination,the effects on physiological activity were studied.The results showed that with the increasing degree of drought stress,conductivity and MDA content were on the rise；chlorophyll content decreased first and then increased,root activity decreased rapidly.After rewatering and drought stress again,the change tendency of each index was as similar as to the first drought stress,but variation amplitude.It proved that drought had a cumulative effect.
