Effects of Low Temperature and Poor Lighting on Anthocyanin Content and Fruit Quality of Eggplant

  • 摘要:   目的  探究低温、弱光、低温弱光处理对茄子幼苗期、花期、果期花青素含量的影响,以及对茄子品质的影响,为茄子的优质培育以及高产栽培奠定理论基础。  方法  以紫黑茄秀娘为试验材料,分别在幼苗期、花期、果期进行低温(18 ℃/13 ℃,250 μmol·m−2·s−1)、弱光(25 ℃/20 ℃,120 μmol·m−2·s−1)、低温弱光(18 ℃/13 ℃,120 μmol·m−2·s−1)、CK(25 ℃/20 ℃,250 μmol·m−2·s−1)等4个处理,测定幼苗期形态及生理特性,不同时期、不同部位的花青素,以及果期果实的品质。  结果  低温弱光胁迫对幼苗生长存在显著影响,在幼苗期低温对幼苗生长及生理影响显著大于弱光及低温弱光,花青素含量均表现为根<叶片<叶脉<茎;在花期,花青素含量依次为花萼<花瓣;在果期,花青素含量依次为果肉<果柄<果皮。茄子不同时期受到胁迫后,不同部位的花青素含量均呈现弱光<CK<低温弱光<低温,各胁迫下果实色泽指数依次为弱光<CK<低温弱光<低温,可溶性糖含量、可溶性蛋白含量、类黄酮含量、总酚含量均呈现低温<低温弱光<弱光<CK。  结论  低温促进花青素合成;弱光抑制花青素合成;在低温弱光双因素互作下,低温因素对花青素含量的影响起主导作用,花青素的合成大于降解,花青素含量增加。低温、弱光、低温弱光胁迫下茄子品质均下降,其中,低温胁迫对茄子的品质影响最大。
