本实验研究了小麦、玉米、菜豆的植株高度与过氧化物酶活性之间的关系,结果如下:①7个高度不同的小麦品种(高度从65cm 至136cm)的胚芽鞘的过氧化物酶活性比较表明:小麦胚芽鞘的过氧化酶活性与小麦植株高度呈负相关性,即高生的小麦胚芽鞘的过氧化物酶活性低,而矮生的小麦胚芽鞘的过氧化物酶活性高,相关系数为-0.91。②4个高度不同的小麦品种(高度从65cm 至102cm)的正在伸长的节间的过氧化物酶活性比较表明:正在伸长的节间的过氧化物酶活性与植株高度呈负相关性。株高65cm 的矮生小麦叶考拉的几个正在
In this experiment, the relationship between plant height and peroxidase activity of wheat, maize and kidney bean was studied. The results are as follows: ①The peroxidase activity of coleoptile of seven wheat cultivars with different heights (65cm-136cm in height) The results showed that the peroxidase activity of wheat coleoptile was negatively correlated with the height of wheat plants, that is, the peroxidase activity of high-yield wheat coleoptile was low, while the peroxidase activity of dwarf wheat coleoptile was high. The correlation coefficient Is -0.91. ② Comparison of the peroxidase activities in the growing internodes of four wheat cultivars with different heights (65cm-102cm in height) showed that the internode peroxidase activity was negatively correlated with plant height. A few of the 65-cm-tall dwarf wheat koalas are now growing
