摘要

利用电子束和氮离子、氢离子注入处理普通鸡冠花干种子，试验结果表明，两种诱变处理均能显著抑制鸡冠花植株的生长、发育，并能有效地诱发花性状变异，变异株率可达0.5%—2%。电子束处理鸡冠花干种子的半致死剂量（LD,50,）经测定为1.2kGy左右；离子注入处理的半致死剂量随注入离子种类不同而不同，N,+,注入的半致死剂量（LD,50,）为1.6×10,17,/cm,2,，H,+,注入的半致死剂量应低于1.6×10,16,/cm,2,。鸡冠花干种子电子束处理的适宜剂量为1.5kGy左右，离子注入处理的适宜方法是N,+,1.6×10,16,/cm,2,。同时鸡冠花对高剂量辐照较不敏感，是一种耐强辐照的资源。

Abstract

Celosia seeds were irradiated by 3MeV electron beams or implanted with 30keV N,+, or H,+, ions, The results showed that the two kinds of treatments could inhibit growth and development of the plants and induce variation of the flower. The variation rate was between 0.5%—2%. LD,50, of the seeds irradiation by the E-beams was estimated at about 1.2kGy. LD,50, of the seed ion implantation varied with the ion. LD,50, of H,+, ion implantation was 1.6×10,17, ions/cm,2, and LD,50, of N,+, ion implantation was less than 1.6×10,16, ions /cm,2,. Suitable treatments of the seeds were 1.5kGy E-beam irradiation, or implantation of1.6×10,16, N,+, /cm,2,. The seeds were not sensitive to higher dose irradiation or ion implantation. And it seems that Celosia seeds have strong radiation resistance.
