|
|
Background: The purpose of this study was to evaluate methods to reduce seeding expenses, thereby increasing farm income. This study investigated the effects of rain shelter controlled cultivation and adapted seeding times on the stable seed production of Scutellaria baicalensis Georgi.
Methods and Results: Seed germination was conducted under 10 condition compose to control, water washing, cold storage at 4℃ for 15 days, seed sterilization with a benomyl pesticides, hormone treated seed by submerging in 100 ppm GA3 with the cold storage at 20℃ and 25℃, darkness in a covered petridish and illuminated with a 1,500 Lux lamp. There were three cultivation type, open cultivation with non-woven fabric mulching, cultivation with a vinyl covering and rain sheltered in a plastic greenhouse. Sowing dates were April 27, May 18, June 7 and June 28, 2013. Plants were spaced 10 ㎝ apart in rows 30 ㎝ apart. Mixed oil cake fertilizer, N-P2O5-K2O (12-10-10) was applied at 600 ㎏ ? 10 a?1.
Conclusions: Optimum germination occured in darkness at 25℃ and cold storage after submerging in GA3. The highest seed yields (4.5 ㎏ ? 10 a?1) occurred in the plastic greenhouse for the April 25 sowing. The highest root yield (17%) was found on April 1, under greenhouse conditions.
