Effects of Pretreatment on the Field Germination Rate of Some Tree Seed

종자(種子)의 전처리(前處理)가 몇 수종(樹種)의 포장발아율(圃場發芽率)에 미치는 영향(影響)

To seek for a proper pretreatment method for increasing field germination rate, field germination rate of 5 tree species including Phellodendron amurense was investigated and was compared among pretreatment methods. The results obtained in this study were as follows ; 1. Field germination rates of Poncirus trifoliata and Fraxinus rhynchophylla among pretreatment methods were significantly different at 1% level, and that of Phellodendron amurense among pretreatment methods were significantly different at 5% level. In thses species, highest field germination rate was observed on the plot of cold moist stratification under the ground (Nochunmaejang ; during 166 days). 2. Field germination rates of Chaenomeles sinensis among pretreatment methods were significantly different at 1% level, and highest field germination rate was observed on the plot of cold moist stratification in the refrigerator (during 110days). 3. Field germination rates of Cudrania tricuspidata among pretreatment methods were not significantly different at 5% level.

수목종자(樹木種子)의 포장발아율(圃場發芽率)을 높이는 종자전처리방법(種子前處理方法)을 찾기 위하여, 황벽나무를 비롯한 5수종의 종자(種子)에 대해 종자전처리(種子前處理)에 따른 포장발아율(圃場發芽率)을 조사(調査) 비교(比較)하여 얻은 주요결과(主要結果)는 다음과 같다. 1. 탱자 및 물푸레나무의 포장발아율(圃場發芽率)은 종자전처리간(種子前處理間)에 1% 유의수준(有意水準)에서, 황벽나무는 5% 유의수준(有意水準)에서 각각 통계적(統計的) 유의성(有意性)이 인정(認定)되었으며, 이들 수종(樹種)은 노천이장처리(露天理藏處理)(166 일간(日間)에서 포장발아율(圃場發芽率)이 가장 높았다. 2. 모과나무의 포장발아율(圃場發芽率)은 종자전처리간(種子前處理間)에 1% 유의수준(有意水準)에서 통계적(統計的) 유의성(有意性)이 인정(認定)되었으며, 냉습적처리(冷濕積處理)(110 일간(日間))에서 가장 높았다. 3. 꾸지뽕의 포장발아율(圃場發芽率)은 종자전처리간(種子前處理間)에 5% 유의수준(有意水準)에서 통계적(統計的) 유의성(有意性)이 인정(認定)되지 않았다.
