Abstract
|
|
|
This study was conducted to find out environment conditions in order to increase of growth and yield of tuberlets in Pinellia ternata(Thunb.) Breit.
The optimal temperature conditions for the growth of tuberlets were good rather temperature fluctuations than constant one and the optimal photoperiod was a 6hr-photoperiod. The growth of tuberlets to the kinds and concentration of growth regulators was good for 0.1ppm 2.41-D, 10ppm kinetin and 50ppm gibberellin treatment, In colchicine soaking treatment, the growth of tuberlets was bad, but bulblets formation was good for 0.05% colchicine treatment for 48hr. -soaking. In colchicine dropping treatment, dry tuber yield was good for 0.1% colchicine treatment with once dropping for one day.
