摘　　要：用60Co-γ射线辐照处理天竺葵、观赏椒种子,观察其发芽率和幼苗生长情况。结果表明:γ射线辐射对这2种观赏植物的发芽率和幼苗生长发育具有不同的影响。对天竺葵的发芽率有促进作用,但抑制幼苗生长;对观赏椒发芽率作用不显著,对幼苗前期生长有抑制作用。The Pelargonium and Capsioum annuum L. were radiated by ^60Co-γ ray and observed the germination rate and growth of seeding, The results indicated that the radiation had different effects on the germination rate and growth of seeding of the two plants. It could improved the germination rate of Pelargonium but restricted the growth of the seeding, as to Capsioum annuum L. , the effect on germination rate was not clear and it restricted the growth of seeding only at initial stages.
