摘要
以新疆红肉苹果为试材,研究其生长发育过程中果肉花青素合成代谢的变化。结果表明:新疆红肉苹果果肉中的花青素含量从5月18日~6月11日逐渐减少,从7月5日~7月29日缓慢增长;在成熟的果实中,果肉花青素的含量是0.36 mg·g-1FW,高于普通品种的苹果,说明新疆红肉苹果是潜在的、良好的花青素来源;在新疆红肉苹果中,可溶性糖含量与类胡萝卜素含量呈显著负相关(R=-0.75),花青素含量与类胡萝卜素含量呈显著正相关(R=0.79),花青素含量与苯丙氨酸解氨酶(PAL)、花色素合成酶(ANS)之间没有明显的相关性,显示可能存在一些消耗花青素的途径。
The changes of anthocyanin metabolism in Xinjiang red- flesh apple [Malus sieversii f. neidzwetzkyana( Dieck) Langenf. ]were studied during fruit development. The anthocyanin content in flesh decreased gradually from May 18 to June 11,but increased slowly from July 5 to July 29. In mature fruits,the anthocyanin content was 0. 36 mg·g- 1FW,which were higher than that of common cultivars. It suggested that the Xinjiang red- flesh apple was a potential and good source of anthocyanin. There was significantly negative correlation( R =- 0. 75) between soluble sugar content and carotenoid content,and significantly positive correlation( R = 0. 79) between anthocyanin content and carotenoid content; no significant correlations were found between anthocyanin content and the activities of pheammonialyase( PAL) and anthocyanidin synthase( ANS),which implied some pathways to consume anthocyanin.
