模拟降水增加对荒漠一年生植物琉苞菊表型可塑性的影响
Effect of simulated precipitation on the phenotypic plasticity of desert annual plant Hyalea pulchella
摘要
Abstract
To explore the response of annual plant Hyalea pulchella to precipitation change, H. pulchella was fed with 2 levels of stimulated rainfall, which were 30% and 50% more than the average precipitation, with no addition as the control. Analysis on phenological characteristics, vegetative growth and reproduction growth were recorded. Results showed that increased precipitation swifted flowering and fruiting stages of H.pulchella in advance by 2-4 d and 2-3 d, respectively. Plant heights, number of leaves and branches were higher in the groups with increased precipitation than the control, indicating that increased precipitation exerted significant impacts on life history characteristics of H.pulchella.关键词
