Abstract: 在广西海岸巫头村野生红鳞蒲桃(Syzygium hancei Merr.et Perry)季雨林中选择重要值较大的红鳞蒲桃、膝柄木(Bhesa robusta (Roxb)D.Hou)、滨木患(Arytera littoralis Bl.)和紫荆木(Madhuca pasquieri (Dubard)Lam.)4个树种进行物候观测研究,结果表明:各树种繁殖生长指数(R/V)以红鳞蒲桃1.4最适宜,膝柄木0.7投入不足,紫荆木5.0投入过大,后两者是濒危植物.红鳞蒲桃和膝柄木在2~3月出新梢,温度是主要影响因子;紫荆木在5月出新梢,降水量和日照时数是主要影响因子.膝柄木9月开花,旱季来临的信号是触发因子.红鳞蒲桃、滨木患和紫荆木均在雨季开花,4个树种的果期均出现在一年中的旱季.
