Co60-γ射线辐照对马蔺种子萌发的影响
A Study on the Germination of Iris lactea Pall.var chinensis Koid Z.Seeds under Co60-γ Radiation
摘要
Abstract
In order to regenerate and popularize the drought- and salt-tolerance economical plant Iris in northwest China,the physical and chemical treatment methods that can stimulate germination of the Iris seeds have been studied.The physical treatment is Co60-γ radiation with different radioactive intensity and the chemical treatment is to soak the seed into the 500mg/kg solution of cytokinin(gibberellin)for 36h.Based on both laboratory and field experiment,the most effective way to disturb the seed dormancy and accelerate the germination is hot water soaking plus Co60-γ radiation.The suggested radiation intensity is 0.2580~0.9030C/kg and the corresponding radioactive density is 2.58×10-4 C/(kg*s).The proper water temperature to soak the seeds is 65℃.The present study is of significance in developing new fodder and medicine-use plants;it is also helpful to restore the deteriorated eco-environment in northwest China and to flourish the local economy.关键词
