芥菜型油菜与甘蓝型油菜嫁接嵌合体的性状表现

以芥菜型油菜(B. juncea)作砧木，以甘蓝型油菜(B. napus)作接穗，形成嫁接嵌合体（以下简称“甘+芥”嫁接嵌合体），对其植物学性状、农艺性状和32P标记的难溶性磷矿粉的吸收能力进行了研究。结果表明，“甘+芥”嫁接嵌合体除叶片出现紫色性状外，其他性状与甘蓝型油菜没有差异，但其农艺性状明显优于甘蓝型油菜和芥菜型油菜。其根系对肥料中难溶性磷吸收能力强，而且多数转移到地上部分，在体内分布较合理。

The Characters of Graft Chimera of Brassica juncea (stock) and Brassica napus (scion)

A graft chimera was formed from Brassica juncea(stock) and Brassica napus(scion).Its botanical,agrionomic characters and the absorbing capacity of hardly soluble phosphate from phosphoric ore powders were studied.Results show that,except the claretls,the graft chimera had no other characters different from these of Brassica napus.Its agronomic characters were much better than those of Brassica napus and Brassica juncea.The root absorbing capacity of graft chimera to hardly soluble phosphorus in fertilizer was strong.And the absorbed phosphorus was transferred mainly to above-ground organs and distributed reasonably in the plant.
