Observations on Flowering, Fruiting and Germination Behaviours of Some Useful Forest Plants of Arunachal Pradesh

There are about 3000 species of flowering plants in Arunachal Pradesh and out of these. About 700 species of forest plants are of economic importance. Observations on flowering, fruiting. Germination period and per cent, plant per cent, viability period, weight of seed/fruit and number of seedlings obtained from seeds/fruits of known weight of important species including bamboo and cane were recorded on the basis of trials conducted from 1978 to 1986. These informations will be of much use for the field foresters to collect required quantity of seed/fruit timely. The germination per cent worked out in laboratories are of very litlle use to the fieldman. Under laboratory condition germination per cent of a species may be 90% but under field condition it can be less than 1% specially for minute seed. Plant per cent gives useful information for collection of required quantity of seed.
