摘  要:
以昆明树木园1983年定植的云南红豆杉人工林为对象,经2007~2008年连续两年的物候观测,获得了该人工林云南红豆杉的物候期数据,以此了解了其物候特性:(1)4月15至30日为云南红豆杉的集中落叶期;(2)云南红豆杉种子集中成熟期为10月中旬至11月中旬;(3)云南红豆杉种子成熟的物候特征在个体间差异较大。通过1991~1992年和2007~2008年的物候特征比较,看出昆明树木园云南红豆杉人工林的云南红豆杉生长发育期有提前的趋势,而休眠期有所延后,此物候期的变化与其气候变暖直接相关。

摘  要:
The phenological characteristics of Taxus wallichiana was studied by taking the trees planted in Kunming Arboretum in 1983 as study targets.The observation results are as follows: 1) the concentrated leaf fall period was April 15 to 30;2) the mature of seeds concentrated on mid October to mid November;3) the seed mature characteristics vary a lot among different tree individuals.Through comparing the phenological characteristics of 1991~1992 and 2007~2008,it was found that the growth time of Taxus wallichiana in 2007~2008 was earlier whereas the dormancy time was later than that in 1991~1992,this change was believed directly correlated with the global warming.
