ects of rainfall pulse on the fecundity and offspring germination of Agrlophyllum squarrosum, an annual plant in Mu-Us Sandland, Semiarid China

摘要

In semi-arid regions in the northern China, rainfall pattern will alter under climate change, with the decrease of light rain days( <10 mm) but increase of heavy rain days ( >25 mm) (Gong et al 2004). The change of rainfall patterns might not only affect plant growth and reproduction (Nicotra ef al 2010), but also have direct effects on offspring germination.
