Abstract:
Taking Melaleuca bracteata seedlings as material,the physiological responses under the different gradient of water stress 15 d and 30 d by pot experiment were studied.The results showed that all of the treated plants had not obvious differences in morphological traits compared with the control (CK) which had provided sufficient water within 15 days.With the increased of water stress and time continued,up to 30 d,the plant appeared the dwarf characteristics and leaf wilting under the severe stress;in addition,the leaf water content and chlorophyll content decreased gradually;Pro and MDA contents had continuously increased and the SOD activity went up at first and then fell down.From above conclusion showed that Melaleuca bracteata seedlings had a certain resistance to the water stress,and with the stress intensity increased,the resistance decreased.
