探讨利用组织培养方法来无性繁殖香蕉的可能性,发现地下茎的离体茎尖是试管内诱导小植株的适宜材料。切下的带有嫩叶的茎尖仅能诱导出一个小植株。但是,带有几个环生着腋芽的、较成熟的具鞘叶的叶原基的茎尖可再生出簇状的小植株。当各个小植株被分离进行继代培养时,又能生出一批新的簇状小植株。由这二种外植体培养出的一些小植株已成功地移植到土中长大成苗。
The possibility of asexual propagation of bananas by tissue culture method was explored. It was found that in vitro shoot tips of underground stems were suitable materials for inducing plantlets in vitro. Cut stem tips with young leaves can only induce a small plant. However, tufted plantlets regenerate from the apices of several more maturely screened leaf primordia with axillary buds. When each plantlet is isolated for subculture, it can give birth to new clusters of plantlets. Some of the plantlets cultivated by these two explants have been successfully transplanted into the soil and grown into seedlings.
