Syzygium grande (sea apple).
Abstract S. grande is a moderately fast growing tree (up to 30 m tall) with natural populations in Bangladesh, India, Indonesia, Malaysia, Myanmar and Thailand. It is planted in hill forests in Bangladesh. It has good timber for poles, railway sleepers and carriage bodies. The mature trees tolerate fire and have been used in fire-breaks in Malaysia. It has a good regeneration capacity. There are about 70 fruits per kilogram (110-115 seeds per kilogram). Seed viability is short (15-25 days). About 60-70% of seeds germinate after direct sowing. In nurseries, seed germination can increase to 75-80% when raised in polybags. It coppices well when young, but coppicing ability declines with age. It can also be propagated vegetatively through grafting and air-layering. The Bangladesh Forest Research Institute (BFRI) has selected Provisional Plus Trees, established clonal orchards and identified seed production areas for tree improvement. At 45 years rotation the MAI recorded from Bangladesh is 5.4 cubic metres per hectare. More research is needed on its genetic variation and assessment of different provenances.
