摘要: 以‘罗田甜柿’试管苗离体叶片为材料,研究了秋水仙素浓度及处理时间对诱导染色体倍性变异的影响。结果表明:0.3%秋水仙素处理4~6 d,可诱导染色体加倍; 与对照比较, 再生变异植株的气孔孔径增大,密度降低,根尖染色体数2n=12x=180,叶片DNA含量为对照的两倍。LI、LⅡ、LⅢ细胞层均加倍的证据表明,获得的倍性变异株为同质12倍体。

Abstract: A study of inducing polyploidy by treating ‘Luotian Tianshi’persimmon in vitro leaflet explants with colchicine solution was perfonned.The results indieated that mutated planflets can be induced by treating the leaflet in 0.3% colchicines solution for 4—6 d.Stomata of the mutated planflets were significantly larger than those of the normal planflets.but the density of stomata were reduced signmcantly.The chromosome number of root—tip cell of mutated plantlets was 2n=12x=180, and nuclear DNA content of the mutated planflets were twice as much as normal hexaploid plantlets.These results suggest that the ploidy of mutated planflets was autododecaploid.
