| 摘要： 先前研究已調查不同月份修剪番石榴的修剪後抽梢、開花及結果時程，並分析果實重量、糖度、酸度、果肉厚度及硬度等性狀。藉此瞭解不同季節修剪之生育狀況及果實品質，以及不同產期果實可能會遇到的氣候風險。今年度的研究將希望提升果實鈣含量以解決夏季果實軟化的問題。In our former research, shooting and flowering time and fruit setting duration of different production times were estimated after the trees had been trained every two months. Fruits characteristics of weight, soluble solides content, acitidy, thickness and hardness of flesh were also measured. Therefore, we had unederstood shoot growth situateion, fruit quality and possible climatic risks would bee meet in different production seasons. Our research, this year, are going to resolve guava softing problem in summer by rising fruits calcium concentrateion. |
