The Growth of Vanda Seedling (Vanda sanderiana) with some Types of Plant Media Acclimatization and Concentration of Humic Acid

Abstract

Vanda is one type of orchid that has the potential to be developed because it has a variety of shapes and colors. Propagation of hybrid vanda seedlings through invitro culture is the right solution to meet market demand. The aim of this research is to find out the right combination of acclimation planting media and humic acid for the growth of hybrid Vanda orchids (Vanda sanderiana). Experiments using factorial Randomized Block Design (RCBD). The first factor is the planting media (zeolite, fern roots, and bagasse) and the second factor is the concentration of humic acid (0 mg / L, 50 mg / L, and 100 mg / L). The results showed that the interaction between the treatment types of planting media and some levels of humic acid concentration showed no significant effect on the percentage of seedling life and on plant growth parameters (height and number of leaves), but significantly different in plant height on the planting media factor. The best growing media is zeolite stone.
