Abstract
The main research objective of this study is drought resistant mechanism of rice. Using Xinliangyou6 rice as materials, the effects of stress on models growth and physiological characteristic and yields are studied. The results indicate that the plant height were decreased, the crop-stem lodging resistance was effectively increased, the physiological index changes occured, the content of Methane Dicarboxylic Aldehyde and proline and total soluble sugar marly all increase, which compared with the treatment of all the water (CK) was applied always, the reduction was significant. Compared with the CK, the yields of the short time water stress treatment in tilling stage (3d) increased 9.2%. With long time water stress by -75 Pa in booting stage, the yield decreased and it will be decreased about 42% in the treatment for the 7-day drought period.
