| 中文摘要: |
| 以 10 年生的 A4 无核荔枝树为材料，研究不同生长调节剂处理对其采前落果及其品质的影响。 结
果表明，10~80 mg/L 的 NAA、GA3均对防止 A4 无核荔枝采前落果、改善果实相关品质具有显著作用。 不同浓度
的 NAA 处理中，以 40 mg/L 处理对降低采前落果率、果实可滴定酸及提高果实的纵径、横径、单果重的效果最
佳；不同浓度的 GA3处理中，以 20 mg/L 处理对采前落果率、果实可滴定酸及提高单果重的效果最好。 |
| 英文摘要: |
| The effects of different growth regulator on preharves fruit-drop and fruit quality were studied, taken10-years-old A4 seedless Litchi trees as material. The results showed that 10~80 mg/L NAA and 10~80 mg/L GA3treatment could prevent litchi fruits to drop before harvest and improve fruit quality significantly. In differenttreatments, 40 mg/L NAA treatment could reduce preharvest fruit-drop rate and fruit titratable acidity (TA) content,as well as improve single fruit size and weight remarkably; 20 mg/L GA3 could also reduce preharvest fruit-drop rateand TA content of fruit flesh, and increase single fruit weight very well. |
