摘　　要： 红豆杉的生长受多种因子的影响,研究这些影响因子的作用对日益兴起的产业化栽培经济效益的实现、森林恢复和野生资源的保护意义重大。从红豆杉的品种、气候因子、海拔、地形和土壤、动物采食及人为因素等方面,综述了影响红豆杉生长的生态因子。温度、光照强度和降水是影响红豆杉生长和分布的3个主要气候因子,其中温度是影响种子萌发的关键因素。红豆杉在缓坡上比在陡坡上生长得好,喜欢酸性、肥沃的土壤。动物的采食对幼苗的生长影响很大,保育植物可以促进红豆杉种群的更新。红豆杉属植物普遍生长缓慢,南方红豆杉是生长最快的品种,经过优良种质的选育,可能成为生产紫杉烷类化合物的一个主要栽培种。还提出了今后几个相关的研究方向。 for economical e growth of Taxus spp. is affected by various factors. The understanding of these factors is important benefit of its cultivation, forest restoration and biodiversity protection. This review focused on ecological factors that affecting the growth of Taxus spp. Temperature, light intensity and precipitation were three main climatic factors affecting the growth and distribution of this species while temperature was a key factor on seed germination. Acid and fertile soil was preferable, and gentle slope was better than steep one. Herbivorous consumption severely affected the growth of saplings. Nursing plants promoted regeneration. Taxus wallichana var. mairei was the fastest growing variety among the slowly growing Taxus spp. Therefore, elite selection for good cuhivars from this variety would be permissible. This review proposed related aspects for further researches.
