摘要/Abstract

摘要： 植物种群营养生长和生殖生长的关系是植物生殖生态学研究的重要内容之一,自本世纪70年代,国外已有大量报道,但国内的研究报道很少。本文在种群水平上研究了人工油松种群一年生雌性枝条和雄性枝条在枝长、直径、叶数、叶生物量、枝生物量及新生枝条在大小孢子球生物量、雌雄枝条长度和生物量等方面的差异,结果表明,一年生枝条除在西方向上雌雄枝条直径差异显著和在东、西方向上雌雄枝条生物量差异显著外,其它处理条件下雌雄枝条在长度、直径、叶数、叶生物量和枝生物量等方面差异均不显著;而对新生枝条的取样分析表明同方向上雌雄枝条在大小孢子球生物量、雌雄枝条长度、雌雄枝条生物量等方面差异均显著或极显著。无论是一年生枝条,还是新生枝条,在东、西、南、北四个方向上其各项指标差异显著或极显著。

Abstract: The relations between vegetative growth and reproduction is one of the important substances in plant reproductive ecology. There have been many research reports abroad in this field since 1970's. However the domestic reports are rare. The experiments on the relations between vegetative growth and reproduction in Pinus tabulaeformis were conducted in an artificial population. The results show that there are not significant different between one year female shoots and male shoots in the same direction, except the diameters in the west, and biomasses in the east and west. There are significant different between new growing female shoots and male shoots in spore biomass, shoot length and shoot biomass in the same direction. The length, diameter, biomass of same sexual shoots are significantly different among the four directions(in west, east, south and north).

Key words: artificial pinus tabulaeformis population, vegetative growth, reproduction
