摘要: 用高效液相色谱法测定了红肉脐橙果实发育期间果肉中番茄红素和β - 胡萝卜素含量的变化,并对果实转色期用不同浓度的外源ABA和GA3 处理后主要色素的含量进行了测定。结果表明: 果肉中番茄红素和β - 胡萝卜素的含量在果实成熟期( 12月21日) 达到最大值(分别为26.79和9.21 μg·g- 1FM) , 分别在果实膨大期和果实成熟期迅速积累, β - 胡萝卜素的合成较番茄红素滞后; 外源ABA处理促进番茄红素的积累, 但不一定促进β - 胡萝卜素的积累; 较高浓度的GA3 在一定程度上抑制番茄红素和β - 胡萝卜素的积累, 但低浓度的GA3 (如50 mg·L - 1 ) , 则能明显促进果肉中番茄红素的积累。

Abstract: The content of lycopene and beta-carotene during fruit development and following exogenous ABA and GA3 treatments at the color break period in flesh of Cara Cara orange (Citrus sinensis Osbeck) was determined by HPLC. The results showed that content of lycopene and beta2carotene in the flesh of Cara Cara orange reachedmaximum (26.79 and 9.21μg·g- 1 FM, respectively) during fruitmaturation; lycopene and beta-carotene accumulated rapidly from August 17 to October 20 and from October 20 to December 21, respectively. Exogenous ABA facilitated the accumulation of lycopene but not always facilitated the accumulation of beta-carotene. Exogenous GA3 of high concentration restrained the accumulation of lycopene and beta-carotene to a certain extent while low concentration remarkably facilitated the accumulation of lycopene.

Key words: Citrus, Lycopene, Beta-carotene, ABA, GA3
