钴60-γ射线辐射锦丰梨枝条的当代效应初报

A Preliminary Report on Current Effect of Cobalt 60-γ Ray Radiation on Jinfeng Pears Branches

观察了钴60-γ射线辐射锦丰梨枝条的当代效应,结果表明:经辐射处理的锦丰梨枝条嫁接后均能成活,芽体萌动和展叶延迟;叶色、外观、叶片大小及厚度、叶序发生不同程度的变化。出现二叉、多叉枝和丛状矮枝等畸形枝条。新梢生长量显著下降,长梢抽叶期长而晚,速生期短,而短梢则表现为夏梢以芽内分化叶丛状蔟生成短枝。

Using the cobalt 60-γ ray radiation Jinfeng pears branches, the results showed that it all can survival the radiation treatment Jinfeng pears branches after grafted, germinating of brood body and the delay of exhibition leaf, the color, appearance, size, thickness and leaf Sequence of leaves in different degrees of change. It appears malformation branch that binary, more cross branch and plexiform dwarf branch. Shoot growth was significant drop, long and late of the leaf development stage, fast-growing period was short, and then short shoot appears summer shoot in bud differentiation leaf plexiform cocooning frame genteration spur. It appeared three kinds of variations, such as spur-type, drooping type and the brood body early maturity.
