IMPACT OF INTER-ANNUAL CLIMATE CHANGE ON SOME PHENOLOGICAL ASPECTS OF HOLOPTELEA INTEGRIFOLIA PLANCH AND GMELINA ARBOREA ROXB

Present study deals with impact of climate change on the phenology of two tree species of Chambal eco-region of Madhya Pradesh, India between the years 2009 to 2011..Meteorological data for twenty years (1990-2011) indicate about an increase in average maximum and minimum temperature by 0.27ºC and 0.53ºC respectively. The yearly precipitation also has reduced during these two decades. It was also observed that the average spring temperature (T24) has increased from 2000 to 2011. The vegetative and reproductive phenology of selected species were differentially influenced due to changes in some climatic parameters. Leaf bud burst, flowering and fruiting of both the species were advanced by significant number of days but the leaf fall in both the species was delayed.
