摘　　要：本文对杉木（Ｃｕｎｎｉｎｇｈａｍｉａｌａｎｃｅｏｌａｌａ（Ｌａｍｂ．）Ｈｏｏｋ．）的雄性不育株与可育株小孢子叶球和叶的呼吸强度进行比较。结果表明不育株小孢子叶球和叶的呼吸强度较可育株弱，能量供应不足是小孢子囊败育的主要原因。TIs authors have investigated the respiratory intensity Of microstrobilus and leaves by combbing male sterile plant with male fertile plant in Cunning hamia lanceolata (Lamb. )Hook. Wo showed here that the resporatory intensity of microstrobilus and leaves of male sterile plant is weaker than that of male fertile plant. The insufficency of energy supply is one of the primary factors of their micrcoporangirm abortion.
