STATE PLAN PROJECT OF GOVT. OF ARUNACHAL PRADESH
- In situ conservation : About 200 native species are being conserved in situ at
- essa Orchid Sanctuary. However, maintenance works like weeding, habitat, improvement of various orchid species at regular intervals could not be carried out due to fund constraints.
- Ex situ conservation : As a part of ex situ conservation number of orchids of different species have been rescued from degraded forest areas of various districts in Arunachal Pradesh and brought under cultivation at Tipi and Itanagar orchidarium and Orchid Sanctuary Sessa. During the year about 500 orchid plants belonging to 52 species and 25 genera have been added to the stock, thus making the total stock of orchids 20000 of 150 species and 50 genera at Tipi, Itanagar, Dirang and Sessa.
- Enrichment of germplasm: During 2003-04 Seven species of orchids are added as new addition to the existing germplasm at ORC, Tipi of which 6 species are collected from out side states and one species is collected from Arunachal Pradesh.
- Multiplication : About 538 nos. of vegetative multiplication are done during the year.
C. HARDENING OF LAB. SEEDLINGS
- Production of Seedlings : (i) Seed culture : 40 species and 2 hybrids are cultured through seeds and about 1800 seedlings transplanted about 500 nos. flasks with various stages of culture are in stock. (ii) Tissue culture : 20 hybrids and 2 species of cymbidium, Vanilla, Dendrobium and Vandaceous group cultured by using apical meristem/ inflorescence node/ axillary buds. About 400 flasks with various stages of culture are in stock. About 600 seedlings are ready for transplanting at Tipi and Itanagar Lab.
- New Records: Collected and identified following 2 orchids species as new addition to India from Arunachal Pradesh during the year. 1. Dendrobium ruckeri Lindl. 2. Oberonia lobulata K&P
- Herbarium: 14 specimens are added in the orchid herbarium, Tipi during the year 2003-04 making total number of OHT Herbarium 3,032 nos. representing a total of 387 species and 101 genera.
- Breeding: During the year 100 breeding trials are conducted at Itanagar and ORC, Tipi involving 15 species and 3 hybrids. Some of the successful capsules are under observation.
About 2000 nos. of lab seedlings were hardened at hardening unit. Tipi, and about 60% seedlings survived.
A total of Rs. 93,705/- only has been earned as revenue during 2003-04 by selling various orchid products at ORC, Tipi.
