벽오동(Firmiana sirmlex W.F.Wight) 가지의 수용성 추출액이 작물발아에 미치는 Allelopathy의 효과 = Allelopathic effects on several crops by the aqueous extract of a Phoenix tree (Firmiana sirmplex W.F. Wight)

국문 초록 (Abstract)

벽오동나무 2년, 3년생 가지를 1월과 4월에 채취하여 수용성 추출액을 희석 농도별 공여작물에 발아 실험하여 Allelopahy의 효과를 조사항목별 결과는 다음과 같다.
발아율은 시료의 년별, 월별에 있어 년별 또 토마토, 벼는 월별 발아억제 효과가 없고 월별은 배추, 갓은 1월에 발아율이 낮았으며, 발아기는 벼가 제일 빨랐으며, 다른 공여작물은 무처리에 비하여 2배 내지 3배 정도의 기간이 더 지연되었으며 발아평균기간은 년수에 관계없이 배추, 갓, 벼는 1월이 지연되었으며, 토마토는 오히려 4월은 지연되었다. 발아양부는 벼를 제외한 공여작물은 4월 채취가 발아양부가 양이었으며, 1월은 불량이 많았다. 농도 30%에서는 중, 불량이었으며, 벼는 년수, 월별, 농도에 관계없이 지수가 양이었다.

Two and three years old branches of a Phoenix tree were respectively collected on January and April, and the aqueous extract from the branches was then treated to four tested crops, Chinese cabbage, leaf mustard, tomato and rice, in order to find the allelopathic effects by different concentration of the extracts. Generally, there were allelopathic effects of the aqueous extracts on the tested crops with increment of concentration and regardless of branch ages and/or collecting season. The results were summarized as follows.
Germination rate of Chinese cabbage and leaf mustard were lower with treatment of the extracts from the branches which were collected on January. Otherwise, there were no significant effects of the extracts on the germination of tomato and rice. Germination time of rice were greater than other crops which germination time were delayed.
Average germination time of Chinese cabbage, leaf mustard and rice were delayed with value of tomato was delayed with treatment of the extracts from the branches collected on April. State of germination of all crops, except rice were high with treatment of the extract on April, and were low on January. In case of rice, it was high without regard to the collection season of branches and concentration of extracts.
