Webexample, among herbaceous grassland species, taller species often ﬂower later than shorter ones (Dahlgren, von Zeipel & Ehrle´n 2007; Du & Qi 2010). However, it is still ambiguous whether ﬂowering phenology largely depends on height growth pattern in grassland species, because two critical ques-tions have not been fully addressed. WebPlant phenology is affected by climate conditions and therefore provides a sensitive indicator to changes in climate.
