Research Abstract

Four issues of problems were investigated concerning leaf phenological events of forest trees namely. Emergence pattern, timing of leaf emergence, leaf longevity and leaf habit (deciduousness and evergreenness) in tropical mountain forests on Mt. Kinabalu, Borneo island Malaysia. All shoots studied in the present study showed evergreen habit at least from 1994 to 1999. Leaf order against leaf position showed two types of leaf-emergence patterns. Actual observation throughout one year also reveals that there are two types of leaf emergence patterns in each of forest types on the tropical montane forests. Timing of leaf emergence was also investigated. Since temperature is constant throughout a year, rainfall and nutrient flush were considered to be important as a cue and critical resource for the new leaf emergence. The effect of nutrient supply on the initiation of new leaf emergence was tested by an experiment where nutrogen and phosphorus were artificially supplied. Results suggested the significance of nutrient supply on new leaf emergence at least in some forests. Leaf longevity ranged from shorter than one year to longer than 5 years. In any of the forest zones studied, there were variations in leaf longevities. Flowering phenology and fruiting phenology of tree species were also investigated in relation to fruit dispersal by birds.
