Abstract

|
|
|
Floret flowering of Orostachys japonicus, a monocarpic and short day plant, should be controlled to continue cultivating. The study was done to examine the effect of transplanted seedling size (large, 18 leaves; medium, 13 leaves; small, 8 leaves) on growth, morphological characters, and flowering. Night-break treatment of 2 hours at midnight were done on August 25 and afterward samples were taken every 2 weeks. Growth, morphological and flowering related characters were measured from each sample. With larger seedling transplanted, plant height, inflorescence length, number of leaves including bracts and stem diameter were increased. Leaves and bracts, stem, root, shoot and total dry weights were increased as transplanted seedlings became larger. Although formed florets were inclined with larger transplanted seedling, they were not flowered because of the night-break treatment, meaning that the larger transplanted seedlings, the more economic yield.
