摘要
综述了解除红豆杉属种子休眠的主要方法,即胚培养、层积法和植物生长调节剂处理法;胚培养可获得较高的萌发率,成苗率变化较大;层积法与植物生长调节剂处理法及二者综合虽更具实践意义但萌发率较低。探讨了存在的主要问题,并对今后的研究方向提出建议。
The major breaking methods for Taxus chinensis seed dormancy were summarized, which included embryo culture, stratification and treatment with plant growth regulators. Higher germination rate could be obtained by embryo culture, but the seedling rate varied greatly. Though the germination rate was comparatively lower, both of the stratification and treatment with plant growth regulators or the combination with the two methods would be more practicable. The existing problems related to T. chinensis seed dormancy breaking were discussed, and the research orientations in the future were proposed.
