Abstract
The study on effect of paclobutrazol on growth and development of Grammatophyllum speciosum
Blume was done. Seeding were cultured in Vacin and Went medium (VW, 1949) supplemented with 0-10 mgL -1
paclobutrazol for 2 weeks before then transferred to acclimatization outside. The spraying of 0-200 mgL -1
paclobutrazol was also studied. After 1 month of acclimatization, the result found that seedling in VW medium
supplemented with paclobutazol from the concentrations of 4 mgL-1 had 100 % survival. While the growth of
seedlings was not different among spraying of paclobutrazol and non spraying treatment.
Keywords : Grammatophyllum speciosum Blume, paclobutrazol, acclimatization
