60Co-γ射线辐射对垂穗鹅观草生物学特性的影响
Effect of Roegneria nutans（Keng）Keng Irradiated by 60Co-γ Ray on Biological Characteristics
摘要
Abstract
In order to discuss mutagenic effects of 60Co-γ ray radiation on the main biological characteristics of Roegneria nutans（Keng）Keng,and provide basic data for the applying of radicalization technology in Roegneria nutans（Keng）Keng breeding,dry seeds of Roegneria nutans（Keng）Keng were irradiated with different dose.Seed germination characters and the main morphologic status were studied.The results showed that：Doses that below 50 Gy could promote seed germination and descent when doses beyond 50 Gy.Determination of half lethal dose was 148 Gy,so the appropriate induced dose was found to be from 0 to 148 Gy.60Co-γ ray radiation had an obvious effect on main morphologic characteristics,the plant height,trillers,leaf width and yield were 16.6%,43.0%,16.2% and 25.5% higher than those of the control.关键词
