变叶木〈Codiaeum.Variegatatum(L)Juss var Pictum〉属大戟科, 变叶木属。原产于热带,为一种常见的热带观叶植物。为提高其观赏价值,选育新品种,1987年5月6日,我们进行辐射诱变的探讨试验,观察了~(60)Co—γ射线在不同的剂量下对变叶木的生根、生长和植株形态的影响。初步确定了变叶木~(60)Co—γ射线辐射的适宜剂量范围,现将结果简报如下: 材料与方法 选取一年生的枝条,剪成 6cm长插条,经~(60)Co—γ射线处理后,扦插于插床内,土
Varied wood Euphorbiaceae, woody. Native to the tropics, is a common tropical foliage plant. In order to enhance its ornamental value and to breed new varieties, we conducted a test on radiation mutagenesis on May 6, 1987 and observed the effects of ~ (60) Co-γ-rays on the rooting, growth and Effect of plant morphology. The suitable dose range of ~ (60) Co-γ-ray radiation was initially determined. The results are briefly as follows: Materials and Methods The annual shoots were cut and cut into 6cm long cuttings and treated with ~ (60) Co- After the cuttings in the slot, soil
