| 摘 要： | 采用营养液培养，对5个不同玉米自交系5种供锌处理的营养特性进行研究。结果表明，不同玉米自交系对不同浓度辞反应的敏感性不同，最适宜的锌浓度为10^-7mol／L，最不适的辞浓度是10^-9moL／L；不同浓度的锌对玉米自交系生长的效应不同，对茎叶的生长影响较大，对根生长的影响相对较小；SN-11为锌敏感玉米自交系。178、邢K36、昌7—2为锌中度敏感基因型，鲁原92接近锌高效基因型。

| Abstract: | Inbred line of maize plants of five genotypes were treated with five Zn solution to test their nutritional characters. The result indicated there was different sensitivity in five genotypes to different Zn concentration . When Zn concentration was 10^-7mol/L, the maize seedling grew very well, it is the most suitable Zn concentration to maize growth. The Zn concentration in which maize seedling grew worst was 10^-9mol/L. There is different effect to different solution Zn concentration among five inbred line of Maize . The solution Zn concentration has obvious effect on the growth of shoot , and no significant effect on root. SN-11 is Zn sensitive inbred line of maize. 178, XingK36, Chang7-2 are middle sensitivity genotypes. LuYuan92 is close to Zn efficient genotype. |
