Abstract

Black orchid (Coelogyne pandurata) and Pearl orchid (Coelogyne asperata) are endemic orchid from Kalimantan forest, shape and color suitable as ornamental flower. Many people collected the orchids from the wild for commercial purpose but not much effort on their propagation. To prevent population decreased, propagation and production of new varities via interspesific hybridisation need to be done. An important step required in plant breeding is to obtain cross compatiblity. Cross compatibility of some orchids from Indonesia are not known, including compatibility of Coelogyne pandurata x Coelogyne asperata. Information on compatibility and fertility is very important to produce good quality seed as propagation material. In this research pollination was performed on orchid plants at 2 until 5 day after flowering and pollination was done in the morning. There are three replicates for each pollination.  Pollination was done with C. pandurata (black orchid) as male parent and C. asperata (pearl orchid) as female parent. The results showed that successful pollination was obtained from pollination at 2 days after flowering. Seed capsule was harvested at 3 months after pollination but not yet perfectly ripe. Seed germination employed in vitro method on Vacin & Went (VW) and VW with modification media. Seed from C. pandurata x C. asperata abled to germinate on VW media with addition of 0,1 mg/l auxin and 0.1 mg/l cytokinin and germinated 9 weeks after planting.

Abstract

Vanda tricolor Lindl. Var. Suavis forma Bali has a specific character than the forma Merapi and forma West Java that is size of flowers and fruits, spots purple in labellum purple colored labelum and floral fragrance. High genetic diversity is one of the major factors in breeding improvement. Increasing the diversity of orchid plant characteristics can be done by giving paclobutrazol. Treatment by paklobutrazol in culture medium aims to inhibit growth both in number of leaves and shoot length so that the plant becomes smaller size than their parent or original. The result of growth resistance that occurs varies based on the concentration of paclobutrazol added to medium Vacint & Went (VW) in culture of seeds V. tricolor orchid added with coconut water with concentration of paklobutrazol Control K0 (0%), K1 (1mg / l), K2 (3mg / l), K3 (5mg / L), and K4 (7mg / l). Each treatment performed 5 times repetition. The result of planting of Vanda tricolor seed explants with paclobutrazol modification in vitro was found 40% cultured imbibition and then protocorm, 8% browning on seed, and 52% contamination. This study showed descriptively the orchid seed Vanda tricolor responded to Vacint and Went (VW) media which was added with plant growth regulator of paklobutrazol, so that it was able to grow and develop until reaching phase 1 that seeds to form protocorm, but statistically the addition of plant growth regulator of paklobutrazol has not show a significant influence on the growth and growth response of orchids Vanda tricolor (P> 0.05) because the observation time is not sufficient for at least 6 months of observation and see the function of paklobutrazol is to slow the growth.
