Regulation of Fruit and Seed Production in Selfing Annual, Vigna unguiculata

일년생 자가수분 식물인 동부의 열매 및 종자 생산의 조절에 관한 연구

Some indices of species of the Arundinella hirta communities in Cheolwon area were studied and the following results were obtained. The vegetational date was analyzed from six grass stands selected with the distance away from the DMZ in Cheolwon area. Species diversity was higher in the stand away from the DMZ than in that neat to it. All six stands are not considered to be free of disturbance. Species composition of the stands might be related to the degree of disturbance. It can be said that the destruction of the vegetation by periodical fire or cutting simplifies the species composition. In the rear district the human inter ference is supposed to be more frequent. But it is supposed to be slight in near the DMZ and that the degree of disturbance is not so destructive. This could be the explanation of high diversity in these stands.
