A Study on Chloroplast of Leaves in Genus Populus

이번 실험에서 Populus 8종(種)에 대(對)한 공변세포(孔邊細胞)의 chloroplast의 립수(粒數), 직경(直徑) 및 형상(形狀)의 변이(變異)를 파악하고 엽내세포(葉內細胞)의 chloroplast내(內)의 chlorophyll함량(含量)의 수종간차이(樹種間差異)를 학인(確認)하였으므로 발표(發表)하는 바이다.

The leaf tissues of 8 Populus species were examined to compare the chloroplast number and feature in guard cells and chlorophyll quantity. 1. The chloroplast number ranged from 10 to 30, but difference in number were not significant among species. 2. The size of chloroplast varied from $3m{\mu}$ to $6m{\mu}$, in diameter. The shape was generally circular. 3. The chlorophyll quantities were significantly different among species. 4. The amount of chlorophyll b was 2.4 to 3.2 times greater than that of chlorophyll a.
