东方百合试管鳞茎培育方式的比较

为促进试管鳞茎抽薹，缩短其形成商品球的时间，以东方百合试管鳞茎为材料，采用不同的培育方式，研究其品质与抽薹率的影响。对东方百合试管鳞茎不同培育方式的比较研究，结果表明：瓶苗冷藏或用基质冷藏，冷藏后的试管鳞茎生理变化规律相同，即淀粉含量、蛋白质含量均降低，可溶性糖含量和还原糖含量均升高；而用基质冷藏或用瓶苗冷藏，暗培养的试管鳞茎抽薹率都高于光照培养；采用暗培养或光照培养，基质冷藏的抽薹率都高于用瓶苗冷藏。工厂化生产百合种苗时宜采用暗培养试管鳞茎结合种前用基质冷藏的培育方式。

Different Culture Methods of Bulblet in Vitro of Oriental Hybrid Lily

In order to advance the bulblet in Vitro bolt and shorten the time of the bulb formation, the bulblet quality and the bolting rate were studied through different cultivation methods of the bulblet in Vitro of oriental hybrid lily. Results showed that: there was no difference in the physiological change rule between cold treatment in substrate and that in bottles, indicating that the contents of starch and soluble protein both decreased during the cold treatment, while the contents of soluble sugar and reducing sugar increased continuously. The bolting rate in dark was better than that in light whether the cold treatment was in substrate or in bottles. The bolting rate with the cold treatment in substrate was better than that in bottles. Factory production of lily seedlings should adopt dark culture cultivation in combination with cold treatment in substrate for bulblet before planting.
