Abstract
To explain the relationship between plant size and seed production, change of sexual organs, relationship between each organs of Convallaria keiskei population, which is located in Gwiyeo-2-ri, Namjong-myeon, Gwangju-si, Gyeonggi-do these were studied from April to August 2002. This study was carried out two ways. One way was to set up the permanent quadrat to explain the change of sexual organs. The other was to carry the collected sample to the laboratory and analysis it to explain the relationship between each organs and energy division of seed production. In the Convallaria keiskei population, the average number of leaf which blooming shoot in the permanent quadrat was 2 and I could find the late leaf size was larger. It was found that, per shoot, the average number of flower was 7.9, fruit was 5.4 and seed was 16.1. Each properties in the sexual organ, underground part size and leaf size, had correlation of 1% or within 5%. The flowering time of the Convallaria keiskei was from April 26 to May 11. Therefore, it can be estimated that the blooming period was $8{\sim}9$ days in just one flower. Among that flowers bloom at the beginning May, 80% fruit at the end of May, and 68% fruit at the end of August. The dry weight of seed had more correlation dry weight of underground part than leaf area.
