摘要:
 为研究大气温度升高对枣果实色素含量的影响,以4年生灵武长枣和骏枣为材料,采用开顶气室模拟增温的方法,设置自然大气温度(对照)和升高大气温度2个水平,测定不同时期枣果实叶绿素、类胡萝卜素、花色素苷和类黄酮含量,以揭示气温升高对枣果实着色的影响机理。结果表明,大气温度升高处理会显著提高灵武长枣和骏枣果实叶绿素、类黄酮、类胡萝卜素和花色素苷含量,但对其在整个发育期的变化趋势无影响,大气温度升高增大了枣果实在膨大期至转色期的叶绿素和类黄酮含量的下降幅度以及转色期至成熟期的类胡萝卜素和花色素苷的上升幅度。说明大气温度升高可有效改善果面色泽,有利于枣果实的着色。
Abstract:
 In order to study the effect of elevated atmospheric temperature on the pigment contents of jujube fruit,taking the trees of four-year-old jujube cultivar “Lingwuchangzao” and “Junzao” as materials,using the open-top chamber to simulate temperature rising.Normal atmospheric temperature was used as the control.The contents of chlorophyll,carotenoids,anthocyanins and flavonoids were determined to reveal the mechanism of the effect of elevated temperature on the coloration of jujube fruit.The results showed that elevated atmospheric temperature treatment significantly increased the content of chlorophyll,flavonoids,carotenoids and anthocyanins in the fruit of two cultivars tested,but it did not change the fruit development regularity during the ripening period.The elevated atmospheric temperature increased the amplitudes of the decrease of chlorophyll and flavonoid contents in jujube fruit from the expansion period to the color change period and the increase amplitude of carotenoids and anthocyanins in the color transition period.It showed that elevated atmospheric temperature could effectively improve the color of fruit surface and was conducive to the coloration of jujube fruit.
