| Abstract: | Under drought stress in the field,study was made on the morphology,photosynthetic characteristics and yield components of three plant types of corn that were the flat type-Yuyu 22,intermediate type-Shendan 16 and compact type-Xianyu 335.The results showed that:(1) Drought stress led to leaf chlorophyll content of three corn varieties reducing significantly, the chlorophyll content of Xianyu 335 was least affected by the drought stress, while the greatest impact was on Yuyu 22.(2) The Pn,Tr,Gs and Ci got sig... |
