Morphology and Physiology Characteristic Responses of Different Provenances of Artemisia ordosica to Drought Stress
摘要
Abstract
than that from Mu Us Sandy land and Desert-steppe transitional zone. 2)Chla,Chlb,Chl(a+b),and Car contents、Chla/b and Car/Chl of A. ordosica leaves showed a trend of first increase and then decrease under drought stress. Contents of Chla,Chlb,Chl( a+b) of A. ordosica leaves from Kubuqi desert were higher than A. ordosica from Mu Us Sandy land and Desert-steppe transitional zone under the severe drought stress. However there were no significant differences in contents of Car and Car/Chl of the three different provenances. The Chla/b of A. ordosica from Desert-steppe transitional zone was greatest,followed by that from Mu Us Sandy land,and then by that from Kubuqi desert. 3 ) Contents of starch,soluble sugars and NSC of three different provenances leaves showed a trend of first decrease and then increase. Contents of starch,soluble sugars and NSC of A. ordosica from Desert-steppe transitional zone were higher than A. ordosica from Kubuqi desert and Mu Us Sandy land under severe drought stress,and contents of starch,soluble sugars and NSC of A. ordosica from Kubuqi desert were higher than those of A. ordosica from Mu Us Sandy land. Contents of starch,soluble sugars and NSC of A. ordosica from Kubuqi desert were higher than those of A. ordosica from Mu Us Sandy land and Desert-steppe transitional zone under slight drought stress.[Conclusion]Through the comparison of morphology and physiology characteristics of three different provenances of A. ordosica,we find that the drought resistance of A. ordosica from Kubuqi desert is stronger than A. ordosica from Mu Us Sandy land and Desert-steppe transitional zone.关键词
