摘　　要：通过对笔筒树为期1 a的连续观测,揭示其年生长发育规律。结果表明:在厦门地区的笔筒树植株生长发育全年无休眠,4-7月和9-10月为营养生长高峰期,11月至翌年3月新生叶片较少,营养生长的最适宜温度为25~28℃;1-2月和4-7月为生殖生长高峰期,8-12月的新生孢子叶较少,生殖生长的适宜温度为15~28℃。植株在树荫较多、空气潮湿的地方营养生长较好,而阳光充足条件则有利于孢子生长。孢子囊群成熟期25 d左右。植株的年新增叶片数与其干高有显著正相关性。The annual growth rhythm of Sphaeropteris lepifera(J.Sm.ex Hook.)R.M.Tryon was studied through a year of continuous observation of cultivated plants in the Xiamen region.There was no period of dormancy for the growth of S.lepifera in the Xiamen area.There were two peak periods of vegetative growth,from April to July and September to October.Fewer new blades germinated during the period from November to March,and the optimum temperature for vegetative growth was from 25℃to 28℃.The two peak periods for reproductive growth were from January to February and April to July.Fewer sporophylls germinated during the period of August to December,and the optimum temperature for reproductive growth was from 15℃to 28℃.Vegetative growth was greater in plants growing under tree shade and in moist air;however,the development of spores was favored by sunny conditions.The sori matured at approximately 25 days.There was a significant positive correlation between the annual number of new blades and the stem height.
