四个砂梨品种的茎尖和腋芽离体培养,获得了新梢并诱导生根。发现不同时期和不同树龄的植珠上取材外植体的存活率有明显的差异,而且,不同的基本培养基,不同的细胞分裂素单独或配合使用,不同的碳源对新梢增殖的影响有所不同,不同品种生根所需的条件也不同。生根植株移栽后生长良好。 The shoot tips and axillary buds of four sand pear cultivars were cultured in vitro to obtain new shoots and induce rooting. The results showed that there were significant differences in the survival rate of explants from different age and different age groups. Moreover, the effects of different basic media, different cytokines alone or in combination, different carbon sources on the proliferation of shoots Different, different varieties of the conditions required for rooting are also different. Rooting plants grow well after transplanting.
