There was no relationship between the number of male flowers per current year shoot and the diameter of 1-yr-old shoots, while an increase was recognized in the number of female flowers per current shoot with increasing shoot diameter. The acorns survived on 1-yr-old shoots that exceeded a certain diameter. The number of current shoots on each 1-yr-old shoot increased with shoot diameter, suggesting an increase of resources in shoots with increasing size. Although no relationship between production of male flowers and shoot resources was found, there was a relationship between shoot resources and female flower-bearing and acorn development.}, pages = {49--53}, title = {コナラの花および堅果数とその枝直径の関係(林学)}, volume = {48}, year = {1996}, yomi = {クニトモ, ジュンコ and サイトウ, ヒデキ} }
