中文摘要 | 為探討採收前水分管理對椪柑果實大小及隔年結果之影響,2004年至2006年期在雲林縣古坑鄉,進行採收前28日或14日斷水處理,每處理4株,含對照組計12株。採收前28日、14日斷水及對照者三年單株平均累計產量分別為1123果、841果及936果。採收前28日斷水者,果實周徑小於23cm之比例,顯著高於採收前14日斷水者,而果實周徑介於23與27cm間之比例顯著少於對照者,隔年結果強度有較對照者少之趨勢。延緩斷水使無葉花序比例增加,葉片累計較多氮素,並使碳氮比之累積較差。 |
英文摘要 | To study the effect of pre-harvest water management on fruit size, yield and alternate bearing of 'Ponkan', irrigation was ceased 28 and 14 days prior to harvest and irrigation was withheld as a control in three consecutive years. The average cumulative yield were 1123 fruits, 841 fruits and 936 fruits, respectively. Ceasing water supply 28 days prior to harvest produced more small fruits (circumference < 23cm) than ceasing water supply 14 days prior to harvest and more medium fruits (circumference > 23cm and < 27cm) and small alternate bearing intensity than the control. However, delaying the refraining of water until harvest increased leafless inflorescence and leaf nitrogen, but decreased carbon/nitrogen ratio of leaf. |
