摘要

「梨仔拔」果實採收後，有呼吸更年高峯及大量乙烯產生，同時果實轉黃；外加乙烯處理可提早呼吸更年上升時間，且在外加丙烯連續處理下，產生自動催化乙烯，表現更年性果實特徵。而「泰國拔」果實後熟期間，沒有呼吸更年高峯，也不產生大量乙烯；在外加乙烯存在時，呼吸率增加，然除去乙烯後，呼吸率下降，重複處理乙烯，可使呼吸率再一次上升；且在丙烯連續處理8天當中，少有自動催化乙烯產生，因此，「泰國拔」之表現類似非更年性果實。

The rises in respiration and ethylene production of the harvested guava fruits of cv. ”Li Zai Ba” were accompanied by the changes of fruit color. Exogenous ethylene treatment of this cultivar resulted in accelerated ripening and climacteric respiration. Propylene treatment enhanced autocatalytic ethylene production. Unlike cv. ”Li Zai Ba”, the cv. ”Tai Guo Ba” guava fruits showed neither climacteric respiration nor significant increase in ethylene production. Autocatalytic ethylene production of this cultivar was not noted after propylene treatment although the respiration and softening were stimulated by ethylene or propylene. Thus, it was concluded that cv. ”Li Zi Ba” behaved like climacteric fruits, whereas, cv. ”Tai Guo Ba” like non-climacteric fruits.
