Abstract

In Petunia hybrida four complementary genes are present, each having, if homozygous recessive a blueing effect on the flower colour. These genes have no qualitative or quantitative effect on anthocyanins and flavonols. In mutants homozygous recessive for one (or more) of the Ph genes the pH of aqueous flower limb homogenates is increased. It is assumed that the Ph genes in Petunia are involved in maintaining the pH in the vacuole fluid in the flower.

摘要

矮牵牛中有四个互补基因，每个基因如果纯合隐性都会对花的颜色产生变蓝效应。这些基因对花青素和类黄酮没有定性或定量的影响。在 Ph 基因（或多个）纯合隐性突变体中，水培花臂匀浆的 pH 值升高。人们假设矮牵牛中的 Ph 基因参与维持花液泡内的 pH 值。
