作者通过对过氧化物酶同工酶分析,探计了番茄从芽期至采收末期的酶谱情况,实验结果表明不同生育期及植株不同部位显示的酶谱是不同的。在生育进程的转化时期,酶谱带数目多,扫描峰高;根和茎基显示的谱带数比其它部位多,特征也明显;综合观察,同工酶分析的取材以芽期为好。 用同工酶分析一代杂种,证明酶谱带的变化不受栽培条件及采种早晚的影响,因此可为签定真假杂交工作提供了一种新的方法。 Through the analysis of peroxidase isozymes, the authors probed the zymogram of tomato from the bud to the end of harvest, and the results showed that the zymograms displayed at different growth stages and in different parts of the plant were different. During the transformation process of fertility, the number of zymogram bands was more than that of the other bands, and the peak was scanned. The number of bands displayed by roots and stems was more than that of other parts and the characteristics were also obvious. Comprehensive observation showed that the isozyme analysis was better in shoot stage. The isozymes were used to analyze the generation of hybrids, which proved that the change of zymogram band was not affected by the cultivation conditions and the effect of seed collection sooner or later. Therefore, it could provide a new method for the authentic hybridization.
