Abstract
This study aimed to explore effect of medium, fertilizer source and concentration on growth and flowering of Phalaenopsis hybrids. Deflasked plantlet were transplanted to nursery tray for 90 days after ex vitro. Plant were grown in bark : sphagnum 2:1, 4:1(v/v), BVB-1 and bark with fertigated Peters 20N-20P2O5-20K2O 0.33 g/L,0.66 g/L and Peters 30-10-10 0.66 g/L. Sphagnum moss were transplanted to 4.5 cm pot with Peters 20-20-20 0.66 g L-1. The results showed that Phalaenopsis Sogo Yukidian ‘V3’ were grown in BVB-1 with Peters 20-20-20 0.66 g/L have the higher shoot fresh and dry weight and total leaf area than other treatment. Root length is the highest in bark with the Peters 30-10-10 0.66 g/L. The higher of leaf number , shoot fresh weight and total leaf area of Doritaenopsis {[Modern Beauty × (Hrai× Hinamatsuri)] × Happy Valentine} were grown in sphagnum moss. Plants transplanted to 10.5 cm pot after 90 days. Both of cultivars were grown in the same medium, except the BVB-1 change to BVB-2. The results showed that plants grown in 2:1(v/v) medium with Peters 30-10-10 0.66 g/L produced more leaf number, shoot fresh weigh and total leaf area. While Dtps. {[Modern Beauty × (Hrai× Hinamatsuri)] × Happy Valentine} were grown in 4:1(v/v) medium with Peters 30-10-10 0.66 g L-1 is the higher than other treatment. Plants were moved to day/night 19/19℃ after 229 days, both of the cultivars, when grown in sphagnum moss, the days to flower stalk emergence and flowering were had short period than others treatment. Phal. Sogo Yukidian ‘V3’ were grown in 4:1(v/v) medium with Peters 30-10-10 0.66 g/L, and Dtps. {[Modern Beauty × (Hrai× Hinamatsuri)] × Happy Valentine} were grown in 4:1(v/v) medium with Peters 20-20-20 0.66 g/L had high number of flowers. Comprehensive, Phal. Sogo Yukidian ‘V3’ were grown in 2:1(v/v) medium and Dtps. {[Modern Beauty × (Hrai× Hinamatsuri)] × Happy Valentine} were grown in 4:1(v/v) medium with Peters 30-10-10 0.66 g/L that had higher leaf number, total leaf area of vegetative growth. The total number of flower and flower performance could reach the standard of commercial value.
