FLOWERING<br />

Flowering has been reported from Indian Botanic Gardens, Calcutta in 1892; from FRI, Dehra Dun in 1941 and 1989<br />

(Naithani, 1990). At Penang, it flowered in 1948 and in Singapore in 1949 (Holttum, 1958). In its native country,<br />

Thailand. this species is reported to flower every year (Anantachote, 1987). In India, it flowers only at intervals of more<br />

than 40 years.<br />

DISTRIBUTION AND ECOLOGY<br />

This species is mainly distributed in Thailand and Myanmar. Cultivated in Malaysia, India and China. It was introduced<br />

in Indian Botanic Gardens, Calcutta before 1892 and FRI, Dehra Dun before 1941. Mostly occurs in dry and poor soil.<br />

Chaomao (1987) mentions it as an intolerant bamboo and grows on south ridge of mountains in Thailand and Myanmar.<br />

CHEMISTRY<br />

The chemical composition of culms is approximately holocellulose 68 per cent, lignin 24 per cent, pentosans 17 per cent,<br />

ash 2 per cent, solibility in hot water 5.7 per cent and in alcohol-benzene 6.1 per cent.<br />

SILVICULTURE AND MANAGEMENT<br />

Weight of seeds collected from different provenances of Thailand showed a variation of 14.5 to 82 g per 40 seeds. The<br />

germination percentage varied from 1 to 86 per cent (Anantachote, 1987). Seed viability can be extended by proper<br />

storage with control of moisture content and temperature (Ramyarangsi, 1990). In vitro callus induction has also been<br />

observed.<br />

PESTS AND DISEASES<br />

The seed-borne fungi recorded from Thailand include Alternaria tenuis, Curvularia lunata, Fusarium semitectum and<br />

Myrothecium sp. (Anantachote, 1987).<br />

USES<br />

In Thailand, tender shoots are considered as delicacies, consumed fresh or made into pickles. It is used as vegetables<br />

and in dried forms. T. regia is grown as ornamental in China and Malaysia.<br />
