摘要
【目的】为了探究红皮梨花青苷与可溶性糖的相关性分析及外源糖的增色作用,【方法】以‘红太阳’梨为试材,分析了果皮花青苷与可溶性糖积累的关系,以及喷施外源糖对‘红太阳’果实着色的促进作用。【结果】结果表明,‘红太阳’果皮花青苷变化呈现2个合成高峰,第1个在果实着色初期,第2个在果实成熟期前20 d,第2个合成高峰期导致了果实的大面积着色;花青苷含量变化与果糖呈极显著正相关,和蔗糖含量有一定联系,但不显著,而与葡萄糖含量不存在相关性。喷施2%的果糖溶液能有效提高果实可溶性糖含量,尤其是果糖的含量,并促进果皮花青苷的合成与积累,使果实更加红艳。【结论】‘红太阳’梨花青苷与可溶性糖存在密切联系,且喷施外源果糖可有效促进果实着色。
[Objective]The objective of the study was to explore the correlation between soluble sugar and Anthocyanin and the effect of exogenous sugar on the coloring of ＇Hongtaiyang＇ pear. [Method]The red Chinese pear variety ＇Hongtaiyang＇ was used as material, and exogenous sugar was applied on ＇Hong- taiyang＇ fruit to investigate its coloring effect. [Result]The result showed that the change trend of antho- cyanin content had two peaks during the growth and development of fruit. The first appeared at the early fruit coloring stage, and the second at 20 days before fruit mature, and the second peak was followed by fruit coloring in large area. The significant positive correlation was found between anthocyanin and fruc- tose, the correlation between anthocyanin and sucrose was not significant, and no correlation between an- thocyanin and glucose was observed. The application of 2% fructose solution effectively increased the sol- uble sugar content in fruit, especially the content of fructose, and promoted anthocyanin synthesis and ac- cumulation, and improved pear Coloring. [Conclusion]There is close relationship between soluble sugar and anthocyanin, and the application of exogenous sugar can significantly improve fruit coloration.
