通过对密叶杨×胡杨 3个杂种类型及其亲本的研究 :①可溶性总蛋白质电泳对比研究表明 :3个杂种之间的相似性最大 ,其次是杂种与亲本胡杨较相似 ,杂种与亲本密叶杨相似性很小。②无盐胁迫条件下叶片ABA含量不反映树种的耐盐性
By studying the hybrids of Populus euphratica × Populus euphratica and their parents: (1) Comparative studies on the total soluble protein showed that the three hybrids had the highest similarity, followed by the hybrids with the similar Populus euphratica, and the hybrids with the parent leaves Young similarity is small. ② ABA content of leaves did not reflect the salt tolerance of tree species under salt-free stress
