Effects of Different Germination Characteristics, Sowing Date and Rain Sheltered Cultivation on Stable Seed Production in Scutellaria baicalensis Georgi

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 for 15 days, seed sterilization with a benomyl pesticides, hormone treated seed by submerging in 100 ppm with the cold storage at and , 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 cm apart in rows 30 cm apart. Mixed oil cake fertilizer, (12-10-10) was applied at . Conclusions: Optimum germination occured in darkness at and cold storage after submerging in . The highest seed yields () occurred in the plastic greenhouse for the April 25 sowing. The highest root yield (17%) was found on April 1, under greenhouse conditions.
