本实验对金花葵(Abelmoschusmanihot)幼苗进行剂量为0、30和50 Gy的电子束辐照,结果表明,电子束辐照对金花葵的成活率有影响,在实验范围内,随着辐射剂量的增加成活率降低;经辐射处理的幼苗在生长过程中有明显的矮化现象,且50 Gy处理的植株明显矮于30 Gy处理的;一定剂量的电子束辐照对金花葵的开花、结实、种子的成熟等生殖生长均有影响,当剂量为50Gy时则未能结实.同时,筛选出了8个适用于金花葵的随机引物,分别为 S10、S101、S168、S198、S217、S223、S248及S249.经RAPD分析显示,30和50 Gy辐照的植株与对照组的遗传距离分别为0.2840和0.3766,30 Gy辐照处理的植株所结种子与对照组所结种子的遗传距离为0.1034.
本實驗對金花葵(Abelmoschusmanihot)幼苗進行劑量為0、30和50 Gy的電子束輻照,結果錶明,電子束輻照對金花葵的成活率有影響,在實驗範圍內,隨著輻射劑量的增加成活率降低;經輻射處理的幼苗在生長過程中有明顯的矮化現象,且50 Gy處理的植株明顯矮于30 Gy處理的;一定劑量的電子束輻照對金花葵的開花、結實、種子的成熟等生殖生長均有影響,噹劑量為50Gy時則未能結實.同時,篩選齣瞭8箇適用于金花葵的隨機引物,分彆為 S10、S101、S168、S198、S217、S223、S248及S249.經RAPD分析顯示,30和50 Gy輻照的植株與對照組的遺傳距離分彆為0.2840和0.3766,30 Gy輻照處理的植株所結種子與對照組所結種子的遺傳距離為0.1034.

Abelmoschusmanihot seedlings were irradiated by electron beam at doses of 0,30 and 50 Gy. Survival rate of Abelmoschus manihot was influenced by electron beam irradiation.Growth was examined and genetic variation was studied by RAPD analysis.Plants irradiated by election beam showed a dwarf phenotype, plants irradiated at 50 Gy were lower than at 30 Gy.The reproductive growth of plants such as blossom, fructification and seed maturation were influenced,and such effect increased with doses;with irradiation at 50 Gy,plants stopped seeding all together.Eight appropriate random primers were screened:S10,S101,S168, S198,S217,S223,S248 and S249.RAPD analysis showed that genetic distance between control group and 30 Gy group,50 Gy group was 0.284 0 and 0.376 6 used leaves as experimental material.Genetic distance between controls seed and 30 Gy irradiated seed was 0.103 4.
