Studies on the Seed Production of Festuca arundinacea Schreb II. Effect of ridge and seedin rate on the seed production of Festuca arundinacea S.
톨 페스큐의 종자생산에 관한 연구. II. 휴폭 및 파종량이 톨 페스큐 ( Festuca arundinacea S. ) 의 종자생산에 미치는 영향
Abstract
This trial was carried out to find out the optimum ridge and seeding rate for the seed production of Festuca arundinacea S. (variety Alta). It was composed of three ridge level (12, 18 and 24cm) and four seeding rates (10, 15, 20 and 25kg/ha) in a split-plot design with 4 replications. The experiment lasted from September 1979 to October 1981. 1. The beginning of heading state was May 12 and the date of full flowering stage was June 2. The optimum stage for the seed harvesting of Festuca arundinacea was about 43 days after beginning of heading stage. 2. The number of panicles were 157 per square meter from the best treatment 18cm ridge with 15kg seed/ha. And the 1000 grain weight was 2.79g for the treatment 12cm ridge with 10kg seed/ha. 3. The average seed yield for two years was 681kg/ha and the largest 831kg/ha for the treatment 18cm ridge with 25kg seed/ha. 4. the average germination rate of the harvested seed was 90.7 percent, and it showed a little higher germination rate from the lower level of seeding rate. 5. The average total DM production with two cuttings of aftermath was about 6715kg/ha. According to the increasing seeding rate and narrowing the ridge, DM yield was higher.
본(本) 시험(試驗)은 톨 페스큐의 채종재배(採種栽培)를 위(爲)한 적당(適當)한 휴폭(畦幅)과 파종량(播種量)을 구명(究明)코자 휴폭(畦幅) 3 수준(水準)(12, 18 및 24cm), 파종량(播種量) 4 방법(方法)(10, 15, 20 및 25kg/ha)으로 분할구(分割區) 4반복(反覆)으로 포장(圃場) 배치(配置)하여 1979년(年) 9월(月)부터 1981년(年) 10월(月)까지 축산시험장(畜産試驗場)에서 실시(實施)하였던 바 그 결과(結果)를 요약(要略)하면 다음과 같다. 1. 톨 페스큐의 출수기(出穗期)는 5월12일이며 개화기(開花期)는 6월 2일경이었고 출수기(出穗期)로부터 채종일(採種日)까지는 약(約) 43일(日)이 소요(所要)되었다. 2.
