摘要/Abstract

摘要： 研究了田间和离体条件下金雀异黄素(Genistein, GNT) 对桃果实着色的促进效应。结果表
明, 在果园中‘新川中岛’桃果实成熟采收前22 d, 用40～120 μmol·L^-1 GNT处理可极显著促进果实花
青素积累, 且具有促进果实增大, 提高可溶性固形物和类黄酮含量以及降低果实硬度和叶绿素含量的趋势。
离体试验表明, GNT能够促进‘中油5号’油桃果皮花青素积累, 而环鸟苷酸( cGMP) 明显抑制GNT的
效应, 暗示着GNT促进果实着色可能与细胞cGMP信号转导途径有关。

Abstract: Genistein (GNT) , a natural isoflavone from soybean, was used to study the effect on peach
( Prunus persica L. ) coloration in the orchard and detached conditions. The results showed that app lication of
GNT at concentrations of 40 - 120 μmol·L^-1 at 22 d before harvest significantly p romoted anthocyanin accu
mulation, and tended to increase the soluble solid content, the flavonoid content and single fruit weight, but
tended to decrease the flesh firmness and the chlorophyll content of the skins, suggesting that GNT might
p romp t fruitmaturity. In detached peach fruits, itwas observed that GNT also p romoted anthocyanin accumu
lation, but cyclic GMP ( cGMP) inhibited the p romotion induced by GNT, suggesting that GNT2induced an
thocyanin accumulation might be related with cellular cGMP signal transduction. Because the p romotion of
GNT on anthocyanin accumulation was stable and significant, it is speculated that the natural substance may
be used in fruit p roduction.
