玉米不同品种幼苗期根水势测定及其抗旱性鉴定

Different Corn Varieties' Roots Water Potential Determin ation and Drought Resistance Identification in Seeding Stage

试验通过对八个玉米品种幼苗阶段不同时期根水势的测定,用模糊数学中隶属函数度的公式进行处理,比较并评价各品种抗旱性。结果表明:郑单958(豫玉33号)属特抗旱类型品种;030×104,农大108(ck),065×150,040×111,655×8号属抗旱类型品种。

In this article, we first test eight corn varieties' water potential of their roots in seeding stage. Then we transit the different stags' test value by using the formula of membership grade in fuzzy mathematical. So we can evaluate the corn drought resistance by using each corn variety different stag's average value of membership grade.The result is verified in the experiment:ZhengDan958,NongDa108,and 030×104 are the drought resistance varieties.
