在红肉脐橙幼果期和着色前分2次喷施不同浓度的外源 ABA和 GA3,研究其对红肉脐橙果肉糖含量的影响。结果表明：10 mg/L ABA处理显著或极显著提高了果实成熟时的葡萄糖、果糖和总糖含量,50 mg/L ABA处理极显著提高了果实蔗糖含量,而100 mg/L ABA处理极显著降低了果实葡萄糖含量；中低浓度的 GA3（10、50和250 mg/L）极显著提高了果实蔗糖含量,10 mg/L GA3处理对果实葡萄糖和果糖含量无明显影响,但极显著提高了果实总糖含量,50、250和500 mg/L GA3处理极显著降低了果实葡萄糖、果糖和总糖含量。表明着色前较低浓度的外源 ABA处理（10和50 mg/L）可提高果实中一种或几种糖的含量,而较高浓度的 GA3处理（250和500 mg/L）则严重阻碍了果肉中糖的积累。

The dynamic concentrations of glucose, fructose, sucrose and total sugar were determined through exogenous ABA and GA3 treatments during young period of fruit and before fruit coloring in pulp of ‘Cara cara’ navel orange. The results are as fol ows: 10 mg/L ABA increased glucose, fructose and total sugar concen-tration significantly or very significantly, ABA treatment of 50 mg/L increased sucrose concentration very significantly, but ABA treatment of 100 mg/L decreased glucose concentration very significantly. GA3 treatment of lower and middle concentrations(10, 50 and 250 mg/L) increased sucrose concentration very significantly, GA3 treatment of 10 mg/L had no remarkable effect on glucose and fructose concentration but in-creased total sugar concentration very significantly, GA3 treatment of 50, 250 and 500 mg/L decreased glucose, fructose and total sugar concentration very significant-ly. Therefore, ABA treatment of lower concentration could increase one or several kinds of sugar concentration, but GA3 treatment of higher concentration (250 and 500 mg/L) restrained sugar concentration in pulp of ‘Cara cara’ navel orange seri-ously.
