| 摘要： 1. 雜交及實生單株高接於成年老樹，促使提早開花結果後進行評估。 2. 已開花結果單株進行果實品質及性狀評估。 3. 初選優良單株提供接穗至產地進行試植。 4. 以氯化鈣或其他含鈣元素處理植株及幼果，尋求提高果實硬度的可能方法，以緩解馬來西亞種可能發生的盛產滯銷壓力。選育出具有優良園藝性狀的鮮食用楊桃用品種，以提高楊桃在國內外市場的競爭力，同時能強化楊桃的貯運性，提高楊桃的貯架壽命。This project plans to use methods of seeding selection, hybridization breeding and introduction to proceed variety improvement of carambola. Expect to achieve in new strain which large fruit, low acid, bright color and can resist long distance storage during transportation. Then phase out existing varieties are aging or retrogression in order to promote market competition and increase farmers income. Some reduction in the incidence of the disorder has been achieved by the application of calcium salt to the fruit as a preharvest spray. A study using CaCO3 500X, 1000X, 1500X, and GA3 1000 ppm, GA3 2000 ppm entered the fruit the greater would be the reduction in breakdown and enhance fruit firmness, quality. |
