Studies on reproductive allocation, floral size and its trade-off with floral number of annual Gentiana

Abstract

Abstract: The reproductive allocation and the trade-off between flower size and flower number of five annual plants of Gentiana in Eastern Qinghai-Tibet Plateau Alpine Meadow were studied. 1) The mass of reproductive structure increased significantly with increasing individual size; 2)There was not certain correlation between reproductive allocation and size of individuals, which suggest species-specific adaptive strategies; 3)Both floral display size and total flower production are increasing with plant size, and the flower number is increasing more remarkably than flower size; 4)The trade-off between total flower production and flower size is exist after controlling for plant size statistically. This result confirms the theory predicts.
