摘要: IMELDA JEANETTE LAWALATA. In Vitro Flowering Induction of Gloxinia (Siningia speciosa) by GA3, Sucrose, Nitrogen and Phosphor. Under direction NURHAYATI A. MATTJIK NI MADE ARMINI WIENDI vitro flowering is a method flower organ induction under controlled aseptic condition. This can be used in all plant including gloxinia. an ornamental having beautiful leaf, color, form, size flower. research consisted three separate experiments using Factorial Design compiled Completely Randomized Block Design. Experiment-I concentration GA3 (4, 6 , 8, 10 mgtl), sucrose (30, 40, 50 dl). Experiment-I1 nitrogen (lx, 1/5x, 1/10x, 1/20x), phosphor 5x). ExperimentI11 5x) at appropriate temperature photoperiodicity. Results showed that gloxinia has not produce any the after 14, 8 weeks treatment, but its vegetative growth was growing until end experiment period. Treatment interaction significantly influenced number leaves. Also, gave significant effect on aqd photoperiodicity affected rate buds, buds
