Abstract
In this research, to prove the actual effects of global warming on the phenology, especially the blooming and sprouting of Prunus mume 'Nankou', 'Nankou' was grown in a controlled high temperature experiment. The experiment was divided into 4 parts, May 10, Jun. 14, Jul. 19 and Aug. 23, in the year 2011, with the 'Nankou' being transferred into the growth chamber during these 4 parts under two conditions, outdoor temperature and 3℃ warmer than outdoor temperature. Overall results show earlier blooming and sprouting in the 3℃ warmer treatment chamber for the second consecutive year. In addition, in some individuals pre-season defoliation occured in August and September 2011 and the number of flower buds and flowers decreased in 2012 of the warming treatment group. In later observations, the difference due to the starting time of warming was no longer relevant on the phenology, especially the blooming and sprouting, but in the sprouting of 2012 and the blooming and sprouting of 2013 was delayed about two weeks in some individuals of the warming treatment group.
