| 摘 要： | 以10个羽衣甘蓝杂交种为试材进行游离小孢子培养,研究胚状体发生和小孢子胚成苗的影响因素,以及小孢子植株倍性鉴定和单倍体加倍方法。结果表明,盛花期为最佳取样时期;培养基中13%的蔗糖较为适宜;继代培养以MS+6-BA 2 mg·L-1+NAA 0.1 mg·L-1为宜,平均增殖系数为5.06;小孢子再生植株成活率74.6%;小孢子植株自然加倍率为23.33%~37.50%;单倍体试管苗的加倍处理以秋水仙素浓度70 mg·L-1,处理时间9~11d为宜,加倍率达54.55%。

| Abstract: | Isolated microspore culture was carried out by ten hybrids of kale (Brassica oleracea L. var. acephala DC.). The frequency of embryogenesis, embryos germinated plantlets, ploidy identification of microspores-derived plantlets and chromosome doubling techniques for haploid plantlets were studied. The results showed that the buds in flourishing florescence were the best for the purpose of microspore culture. The sucrose content of 13% was optimal in medium. MS+6-BA 2 mg·L-1+ NAA 0.1 mg·L-1 was optimal medium for subculture and the average propagation quotiet reached 5.06. The survival rate of microspore-derived plantlets reached 74.6%. The DH plants rate of spontaneous was in the range of 23.33%-37.50%. The treatment of 70 mg·L-1 colchicine for 9-11 d was optimal for haploid seedlings and led to 54.55% doubled haploid plantlets. |
