摘要
研究了多年生一次性生殖植物大百合两个种群果期生殖资源在个体和果实水平上的等级分配.结果表明:两个种群植物个体生产的果实数与每果质量均不存在权衡关系,即使是在控制植物个体大小后.两个种群每果种子数量与单粒质量也没有权衡关系.
Hierarchical allocations of reproductive resources at the individual and fruit levels with reference to fruiting stage were examined in two populations of Cardiocrinum cordatum （Liliaceae）, a monocarpic perennial herb. No evidence for trade-offs between fruit number and mass at the individual plant level was observed in either population, even with controlling of plant size. There were significant positive relations between individual seed mass and seed number per fruit in both populations.
