Dipterocarpoideae in Southeast-Asia
l Widely distributed – Mainland and insular SE-Asia l Dominating lowland rainforests and monsoon forests in SE-Asia – 50-80% of wood volume – Keystone group l Important timber species – Trade name: Meranti, Balau, Keruing, Kapur l Many endangered taxa Dipterocarp forest on Borneo 5 Background: Dipterocarpaceae
Dipterocarp: growth habit
l Medium-sized – emergent trees – Mainly climax species – Often long, straight boles – Slow to fast growth
Dipterocarpus Shorea selanica (<60 years) 6 condoriensis Background: Dipterocarpaceae
Dipterocarpaceae – Reproductive biology
l Hermaphrodites l Zoogamous (mainly insect- pollinated) – Bees, butterflies – Thrips l Self compatible, mixed mating system – t typical 60-90%
7 Dipterocarpus condoriensis Background: Dipterocarpaceae
