Research progress on the effects of climate change on plant phenology of natural grasslands
Plant phenology has always been a hotspot and frontier research in plant evolutionary biology,plant eco-logy,and climate change ecology,as it is closely associated with plant adaption and evolution,interspecies rela-tionship,and ecosystem structure and functions,and it is greatly sensitive to climate change.Here,we review the main progresses and problems about the responses of the staring date and duration of phenological sequences to cli-mate change based on three levels(i.e.,individual,population,and community)with seven phenological sequences(i.e.,onset of green-up,first budding-set,first flowering,first fruiting-set,nutrition after fruiting-set,first coloring,and complete coloring).We further proposed some scientific questions and prospects to promote the development of plant phenological studies in China.
