辽东楤木(Aralia elata)是五加科楤木属木本植物,它的嫩芽营养丰富,是一种珍贵的药食蔬菜。由于该植物资源已渐趋枯竭,我们曾利用组织培养技术对辽东楤木进行快速繁殖研究,并已获得再生植株。为了能够利用该技术对辽东楤木进行大规模快速繁殖,使试管苗的工厂化生产得以实现,我们进一步对愈伤组织的诱导,胚状体及其增殖与继代培养和试管苗的分根繁殖进行研究。现将结果报道如下。
Aralia elata is a woody plant belonging to the genus Gracilaria, which is rich in tender sprouts and is a precious medicinal vegetable. As this plant resource has been gradually depleted, we have used tissue culture techniques to conduct rapid propagation of Alnus cremastogyne and have obtained regenerated plants. In order to be able to use this technique to large-scale rapid propagation of Alnus cremastogyne, factory production of test-tube seedlings was realized. We further studied the induction of callus, embryoid body, its proliferation and subculture, Breeding for research. The results are reported below.
