Ｓｕｒａｎｙｉ［１］（１９７３．１９７６）将李属（Ｐｒｕｎｕｓ）植物分成雌性表现和雄性表现两个种群，并以花内每毫米雌蕊长度的雄蕊数来表示。他发现雄蕊数（ＡＮ）与雌蕊长度（ＰＬ）的比值为１．７－１．９者，自交能育，高于或低于这个比值者自交不育。我们将这个比
Suranyi [1] (1973, 1976) divided the Prunus plant into two populations, female and male, and expressed as the number of stamens per pistil length per flower. He found that the ratio of stamen number (AN) to pistil length (PL) was 1.7-1.9, self-fertile and self-fertile at or above this ratio. We will compare this ratio
