摘要: 为研究疏花对杧果坐果和果实成熟的影响,以台农一号杧果为研究对象,以不疏花为对照,以短截花穗为处理,即在开花初期对花序主轴进行不同程度(1/3、1/2和2/3)的剪除处理,测定不同处理的坐果数、单果质量、果实硬度和糖酸含量等指标。结果表明:(1)3种疏花处理对杧果单花穗最终坐果数量没有显著影响,但能显著(P<0.05)减少果实发育过程中的生理落果。(2)3种疏花处理组的果实硬度、总有机酸和柠檬酸含量均显著低于对照组,而可溶性固形物含量、总糖、蔗糖和叶黄素含量均显著高于对照组,表明3种疏花处理可促使果实提前成熟。(3)疏除1/2和疏除2/3处理组的果实平均单果质量和果实横纵径均显著高于对照组,而且疏花处理的果实成熟均一度高于对照组。综上所述,疏花处理能减少杧果果实生理落果并促使其提前成熟,且能保持杧果成熟度的一致性。疏去花序主轴全长的1/2和2/3对减少台农一号杧果落果和促早熟的效果更佳。

Abstract:

To study the effects of flower thinning on fruit setting and ripening of mango, flowers of mango cultivar ‘Tainung No. 1’ were thinned along the main axis of the inflorescence at different thinning degrees (thinning 1/3, 1/2 and 2/3) at early flowering stage, while unthinned ‘Tainung No. 1’ trees were used as control. The fruit setting number, single fruit weight, firmness, sugar and acid content of the different treatments were measured. The results showed that: (1) Three flower thinning treatments had no significant effect on the number of fruits per inflorescence compared to the control, but could significantly (P<0.05) reduce physiological fruit dropping. (2) Fruit firmness, total organic acid and citric acid contents in the three flower thinning treatment groups were significantly lower than those in the control group, while soluble solids content, total sugar, sucrose and lutein contents were significantly higher than those in the control group, indicating that the three flower thinning treatments could promote premature fruit ripening. (3) The average fruit weight and the transverse and longitudinal diameters of the fruit in the 1/2 and 2/3 treatment groups were significantly higher than those in the control group, and the fruit ripeness in the three flower thinning treatment groups was higher than that in the control group. In conclusion, flower thinning can reduce physiological fruit dropping, advance fruit ripening and maintain ripening uniformity of mango fruit. Removal of 1/2 and 2/3 of the total length of the main axis of the inflorescence had a better effect on reducing fruit dropping and advancing the ripening stage of mango cultivar ‘Tainung No. 1’.
