摘要
The aim of this study was to find out the impact of climate change, if any, on the phenophases of 11 multipurpose tree species, growing as block plantation at one site, during eight years (1999 - 2006). Close monitoring of important fuel, fodder and timber tree species, has indicated significant shift (advancement) in the phenophases. Increase in monthly temperature above the normal has advanced leaf emergence and flower initiation phases. The climate change has prolonged the growth period of 10 out of 11 multipurpose tree species ranging between 31 and 46 days within eight years. The average maximum monthly temperature increased between 0.5 and 8.1 degrees C, whereas annual rainfall declined from 1213.9 mm in 1999 to 969.4 mm in 2006. The average minimum monthly temperature remained unchanged during 1999 - 2006.
