An innovative method of production of planting stock of Hopea odorata Hopea helferi and Hopea wightiana in the shade houses

Tsan F.Y., . and Ahmad Fauzi M.S., . and Wan Rasidah K., . (2003) An innovative method of production of planting stock of Hopea odorata Hopea helferi and Hopea wightiana in the shade houses. [Proceedings Paper]

Production of planting materials of Hopea odorata Hopea helferi and Hopea wightiana was limited by the recalcitrant behaviour of their seeds. These seeds generally survived 2-4 weeks after they shed from their mother trees. Only H. odorata seeds retained their viability of above 60 when cold stored for a period of up to 2 months at 18- 2 deg C. The seedlings of three species however could be maintained at a slow growth phase at densities of 300-600 seedlings/m2 in the shade houses of 20 and 30 RLI depending of the species. The survival rates were above 70 while the height and stem diameter growth was only approximately 10cm and 0.2cm respectively at one year after storage under such low light conditions.

Abstract

Production of planting materials of Hopea odorata Hopea helferi and Hopea wightiana was limited by the recalcitrant behaviour of their seeds. These seeds generally survived 2-4 weeks after they shed from their mother trees. Only H. odorata seeds retained their viability of above 60 when cold stored for a period of up to 2 months at 18- 2 deg C. The seedlings of three species however could be maintained at a slow growth phase at densities of 300-600 seedlings/m2 in the shade houses of 20 and 30 RLI depending of the species. The survival rates were above 70 while the height and stem diameter growth was only approximately 10cm and 0.2cm respectively at one year after storage under such low light conditions.
