| Abstract: | 【Objective】The purpose of this project is to compare the salt-tolerance of these thirteen wheat varieties.【Method】The seeds of thirteen different wheat varieties were taken as testing materials.These materials were stressed by the Na2SO4(the Na2SO4'Salt concentration is 0.5%,1.0%,1.2%,1.4% and 1.6%).After stress,seed germination rate,germ length and relative salt-harm rate were measured.【Result】The result shows that different wheat varieties can endure different harms by Na2SO4 stress.The half to death concentration of Chongqing 4 and 99110-26 is higher than 1.6%.The half to death concentration of Jia 163,Chongqing 3,Xindong 22,Xindong 26,99034,Xindong 17,Jinmai 31 and Yu 4110 is 1.6%.The half to death concentration of Lu 23,Zhongguochun and Xindong 18 is 1.4%.【Conclusion】The salt-tolerance of these thirteen wheat varieties in order of strength is 99110-26 > Chongqing 4>Jia 163 > Chongqing 3 > Xindong22>Xindong26>99034>Xindong17>Jinmai>31>Yu4110>Lu23>Zhongguochun>Xindong 18. |
