利用动态比较方法对深州蜜桃自然杂交后代进行了研究,结果表明,叶柄粗和叶形指数在童期的变化动态与成年期和嫁接树不同,可望作为判别阶段发育进程的标志性状。根据标志性状依叶位的回归变化,试估计了群体平均生理童程转折点(83.5cm)及平均转变区范围(38.2cm),平均结果高度为121.7±16.4cm,株间的转变区大小相对稳定,结果部位的高低较大程度上受生理童程的影响。株间童期叶性状的均值差异不足以判断童程高低。
The dynamic comparison method was used to study the natural hybrid progeny of Shenzhou Peach. The results showed that the changes of leaf petiole roughness and leaf index in childhood were different from those in adult and grafted trees, and could be used as the traits of the developmental process of the differentiation stage. According to the regression of leaf traits according to the traits of leaf traits, the mean physiological transition point (83.5 cm) and the average transformation area (38.2 cm) were estimated. The average height of the results was 121.7 ± 16.4 cm. The size of the transformation zone was relatively stable , The level of the results of the site to a greater extent by the impact of physiological child process. The mean difference in childhood leaf traits was not enough to judge the level of children.
