本文应用０（对照），０．１５，０．３０，０．４５，０．６０，０．７５，０．９０，１．０５，１．２０，１．３５及１．５０ｋＧｙ剂量的６０Ｃｏγ射线照射花生、大豆、红豆、绿豆及眉豆等５种食用性植物种子，测定其形态学和生理生化上的变化。结果表明：不同种类的食用性植物种子具有不同的辐射敏感性，其出苗率、苗高、初生叶面积、初生根活力、初生叶片叶绿素ａ、ｂ（ａ＋ｂ）含量等与照射剂量呈显著或极显著的负相关；初生叶片叶绿素ａ／ｂ比值则与照射剂量呈显著的正相关；不同种类食用性植物种子具有不同的叶绿素ａ、ｂ、（ａ＋ｂ）含量及叶绿素ａ／ｂ比值；叶绿素（ａ＋ｂ）含量的变化是由叶绿素ａ与ｂ二者含量的共同变化所引起的。试验综合指标表明，各供试种子的辐射敏感性大小次序表现为：眉豆＞花生＞红豆＞大豆＞绿豆
In the present paper, 60Coγ-rays at 0 (control), 0.15,0.30,0.45,0.60,0.75,0.90,1.05,1.20,1.35 and 1.50kGy doses Five kinds of edible plant seeds such as peanut, soybean, red bean, mung bean and black pomegranate were irradiated, and their morphological and physiological and biochemical changes were measured. The results showed that different kinds of edible plant seeds had different radiation sensitivity. The seedling emergence rate, seedling height, primary leaf area, primary root activity, chlorophyll a, b (a + b) (A + b) and chlorophyll a / b ratio. Chlorophyll (a + b) was significantly correlated with the chlorophyll a / b ratio of young leaves. ) Content changes are caused by the common changes in the content of both chlorophyll a and b. The comprehensive indexes of the experiment showed that the order of the radiation sensitivity of the tested seeds was as follows: black bean> peanut> red bean> soybean> mung bean
