Abstract:
Taking the annual Cinnamomum migao H.W.Li as material，in a period of 22 days natural drought stress treatment，the effect of different stress time on growth，leaf anatomical characteristics and photosynthetic pigment contents of Cinnamomum migao H.W.Li were studied，in order to assess the ability and countermeasure of tolerating drought in the species.The results showed that with increasing stress time，their growth targets was significantly inhibitted；Chl a and Chl b increased after the first decreased and then decreased，Chl a/b opposited and Car first declined then increased；leaf thickness，the thickness of the skin，veins perimeter and area decresed at first and then increased；spongy tissue upward，and palisade tissue and CTR decresed at first and then increased.The study showed that Cinnamomum migao H.W.Li during drought stress could improve its drought resistance by changing the organizational structure of the blade.
