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.

AbstractThis study describes the development of a micropropagation protocol for Pinguicula vulgaris using cultures initiated from in vitro produced seedlings. P. vulgaris is a carnivorous plant with a northern, disjunctly circumpolar distribution and specific habitat requirements, and is hence becoming increasingly rare. Shoot proliferation was significantly influenced by Murashige and Skoog (MS) macronutrient concentration, showing higher proliferation rates in 1/4MS, but was not affected by the addition of 0.1 mg/L 6-benzyladenine (BA) or zeatin (Zea). The best medium for propagating P. vulgaris was plant growth regulator (PGR) free ¼MS. An average of 7.62 new shoots per initial explant could be obtained after 8 weeks of culture, of which over 79% produced roots during proliferation. Moreover, rooting percentages of 100% were obtained for the initial explants in all the tested media, including media without PGRs. The plantlets were successfully acclimatized to ex vitro conditions, exhibiting normal development.

Forcing Solution

Vanhoutte's spiraea has been propagated in vitro using explants from softwood growth of dormant stems forced in a solution containing 200 mg/l 8-hydroxyquinoline citrate (8-HQC) and 2% sucrose (Yang and Read, 1989). Objectives to further utilize this system were to determine the feasibility of applying plant growth regulators (PGR) via the forcing solution to softwood growth from forced dormant stems and to study the resulting influence on in vitro culture. BA and GA3 were placed in the forcing solution at various concentrations, including a zero PGR control. Explants were cultured on Linsmaier and Skoog (LS) medium containing zero PGR or different amounts of BA or thidiazuron (TDZ) or combinations of BA and IAA. Control explants placed on LS medium supplemented with 5uM BA with or without 1 or 5uM IAA, or with 0.5 or 0.75 uM TDZ alone produced the best shoot proliferation. BA in the forcing solution stimulated micropropagation, while GA3 caused less proliferation than explants from control solutions. Forcing solutions containing PGR are useful for manipulating responses of plant tissues cultured in vitro and for studying PGR influence on woody plant physiology.
