中国特有植物四福花的生物生态学特征初步研究

A study of the Ecological Characteristics of Chinese Endemic Plant Tetradoxa omeiensis

  • 摘要: 野外调查了我国特有植物四福花的分布现状及生物生态学特征,考察结果表明:仅在四川省峨眉山地区海拔2 330 m左右的针阔混交林中发现该植物的5个种群,分布区域极为狭窄;适宜四福花生长的基质为附生于乔木根部和枝干的棉藓。对生态环境的苛刻要求和有性繁殖障碍应该是导致四福花特有濒危的主要原因,就地保护及开展种子繁育等方面的研究是保护该物种的有效方式。

     

    Abstract: An investigation was conducted on the distribution and the ecological characteristics of Chinese endemic plant Tetradoxa omeiensis. The results have shown that only five populations of T. omeiensis are found on Mountain Emei with a very narrow distribution,growing in coniferous and broad-leaved mixed forest with an altitude of about 2 300 meters. The stroma suitable for Tetradoxa omeiensis is Plagiothecium denticulatum,an epiphyte growing on tree roots and branches. Harsh environment and difficulty in sexual propagation are the main reasons which lead to the endangerment of Tetradoxa omeiensis. Studies on in-situ conservation and seed breeding are the effective ways to protect this species.
