Effect of shade and forcing date on growth and flowering of potted Rhododendron obtusum



Effect of shade and forcing date on growth and flowering of potted Rhododendron obtusum



Journal of the Korean Society for Horticultural Science 36(5): 641-648



Flower and growth responses of Rhododendron obtusum 'Red-1', 'Purple-1' and 'White-1' as influenced by light shade and forcing date were investigated. The first flower initiation was observed in late June in three varieties. It took to form carpels for 28 days in 'Purple-1', 35 days in 'Red-1' and 46 days in 'White-1' from flower initiation. According to decreasing shade level until 60% of natural light, there were increased in growth, chlorophyll and stomatal aperture whereas the flower bud initiation was delayed two or three days. The buds of flowering of 'White-1' were decreased about 70% at 30% light shade, and 12% at 60% light shade, however, all the buds of 'Red-1' and 'Purple-1' were opened regardless of light shade. The flowering forced on Nov. 30 was accelerated about 20 days in 'Red-1', 14 days in 'Purple-1' and 25 days in 'White-1' as compared to forcing on Oct. 30. As light shade was increased, flowering was accelerated 3 or 5 days.
