To study variability, heritability and genetic advance in Bambusa balcooa, culm height, culm girth and number of new shoots were recorded at four different age groups from vegetatively propagated six plus bamboo (clump/ genotypes) selected in different areas of Arunachal Pradesh and Assam. Significant variation was obtained in plant height and number of new shoots in all four successive ages. High heritability accompanied with high genetic advance for plant height and number of new shoots provide clear cut index of these characters in selection, improvement and multiplication for higher yield of biomass.- Forest Types of Lohit District, Arunachal Pradesh - a Brief Account of the Flora

Populus ciliata and Populus gamblei are the two common poplars seen in Arunachal Pradesh. Their natural regeneration over the sub-tropical and temperate forests are very good. They come up well on exposed freshly turned soils, land slips, etc. They can be easily raised vegetatively by using branch cuttings and ischolar_main suckers quick to establish, fast growing and profusely coppicing. All these characters suggests suitability in agroforestry, soil conservation and jhum reclamation work in Arunachal Pradesh for which there is a vast scope in the State.- Standardisation of Nursery Technique (use of Different Germination Media and Watering Methods) of Anthocephalus chlnensis

Aquilaria agallocha (Agar-wood) is a very valuable tree of North-eastern region of India and is distributed along foot-hills of evergreen and semi-evergreen forests. The tree flowers and fruits at an age of 7 to 9 years. The capsules ripen in second week of June and 1500 seed weigh to a kg. Seed germinates in 10 to 12 days and is viable for 30 days. Initial germination is 65% and it reduces to 5% after three weeks. Regular plantations are not raised due to uncertainty of agar-wood formation. Agar-wood formation is regarded as a pathological product. Many workers have studied agar formation since 1929 but could not work out a suitable technique for agar-wood formation. Agar tree is attacked by a defoliator (larvae of family Thyrididae) which can be controlled by spraying 0.1% Fenitrotbion or Thiodon.- 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.- Effect of Shade and Mulch on Germination of Chukrasia velutina, Roemer

Coptis teeta Wall.- a small perennial herb popularly known as Coptis or Mishmi tita is an important medicinal plant used for various diseases. The specific name Tita has been derived from its bitter taste. It is found in India only and occurs in temperate regions of five districts of Arunachal Pradesh. Over last few years, its cultivation has been taken up by local people in Arunachal Pradesh and on a limited scale in Nagaland. The Forest Department, Arunachal Pradesh has also taken up its cultivation. It can be cultivated by seedlings raised from seed or from wildings. The crop mature in 6-10 years depending upon source of planting materials. Harvesting is done during winter season. On an average 124 kg dry rhizome per hectare is harvested with a spacement of 30 × 30 cm. The net income from one hectare is obtained around Rs. 16,800/- (Yearly income Rs. 1680/-).- Bamboo Improvement Works in Arunachal Pradesh

Arunacbal Pradesh Is very rich in bamboo having more than 30 species in wilderness. Bamboo is used by the tribal people for a variety of purposes and is very much linked with their socio-economic needs. Keeping in view the importance of bamboo, its improvement work was taken up in Arunachal Pradesh during 1980 with the objective to establish germ-plasm banks of improved materials and to multiply it for supplling to the villagers. Eight important species of bamboos were taken up and plus bamboo were selected from the bamboo grown in the villages and also from natural forests. Offsets were purchased from the villagers and bamboo germ-plasm banks were established during 1984 over 6 hectares at Chessa and Namsai. Among the plus bamboo BB/CH-4, BT/NS-13, BT/CH-7, BP/CH-3, BP/CH-7, BN/CH-I, Nangal CH-2 and CH-4 bave shown superiority over other plus bamboo.- Study of Bamboos Through Establishment of Bambusetum in Arunachal Pradesh

The establishment of bambusetum at the Van Vigyan Kendra has triggered research on bamboos. Though a large number of bamboos were planted initially, many of them died due to wild animal damages and unfavourable climatic conditions for high altitude bamboos. The bambusetum could supply regularly rhizomes and planting stock to different aggencies. It will be worthwhile to create more such bambusetum covering different climatic zones. It is all the more essential for the high altitude bamboos. The bambusetum could also act as refuge for rare and endangered species of bamboos. Further observations could yield valuable results which could assist in better management and economy of bamboos.- Silvical Characteristics of Duabanga grandiflora Roxb. Ex DC (Sonneratiaceae)

Duabanga grandiflora is a fast growing species occurring naturally in Arunachal Pradesh, Andaman Islands, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim and Tripura. Earlier plantations of this species were raised by direct seed sowing and It was found that pricking out of seedling was difficult. Now, nursery technique has been developed. Seed is very minute, 54000 seeds weigh to a gram Seed is sown in the mother beds from first week of May to first week of September. Germination is 80% under laboratory conditions and 4-6% under nursery conditions. Seed is viable for 10-12 months. Seeds germinate in about 10-12 days and seedlings are ready for pricking out when they are 2-3 cm high (In 60-65 days after germination). The species can be worked on a rotation of 30 to 35 years. By that time the crop will attain a diameter over 50 cm and it has many advantages over other species for less damage by Mikania species, and managing on short rotation. It requires little care and can be grown on poor soils. There are two main pests which cause maximum damage in plantation and nursery. They are Halica sp. and Auletobius consimilis. The former causes damage in nursery and the latter in nursery as well as in plantations.- Phenological Study of Trees in Arunachal Pradesh
