CHENG Yohou , ARAKAWA Osamu , SAWADA Shinichi

鉢植えのリンゴ幼樹を用いて，シンク・リミット状態における光合成速度低下の機構について解析した．3日間の連続明期（CL）処理によって，光合成速度は38％，気孔コンダクタンスは58％，細胞間隔CO2濃度は9％，それぞれ低下した．同時に葉内デンプン含量は対照樹の2.8倍に増加した．従って，CL処理によって，リンゴ幼樹はシンク・リミット状態になった．しかし，そ …

皆伐母樹保残施業から30年後のブナ林と, 10年前に弱度の伐採が行われたブナ林で施業法を評価した。皆伐母樹保残施業地では, 伐採10年後にブナの更新完了基準を満たしていたが, 現在ではブナは小サイズに偏り, ホオノキやウワミズザクラ等に被圧されていた。これは, 更新の初期段階で下された更新の成否判定が妥当ではなかったことを示す。弱度の伐採でも, 高密度で更新したのはウダイカンバやホオノキ等で, ブ …
