摘要: 以7 个香蕉品种未成熟雄花为外植体均获得了分生小球体(meristematic globules) 。分生小球体的诱导率因基因组型和品种而异, 为15 %~81 % , 分生小球体的特点及开始出现的时间也受基因组型和品种的影响。以分生小球体为起始材料, 建立了‘广东2 号’、‘华农7 号’及‘河口龙牙’3 个品种的胚性细胞悬浮系, 并通过体胚发生途径获得了前两个品种的再生植株。

Abstract: Meristematic globules were induced from immature male flowers of 7 different banana cultivars. The induction percentages of meristematic globules from immature male flowers was from 15 % to 81 % , depending on the cultivars. Furthermore , both of the characters and the induction time for the appearance of meristematic globules varied with the cultivars.Embryogenic cell suspensions (ECSs) of 3 banana cultuvars ,‘Guangdong 2’,‘Huanong7’and‘Hekou Longya’were established successfully from meristematic globules , and regenerable plants were got successfully from the ECSs of the first two cultivars.

Key words: Banana, Meristematic globules, Embryogenic cell suspension, Plant regeneration
