四、果实发育过程中色泽的变化(一)色素种类与果实色泽当前,世界上的苹果栽培品种,已知多达一万两千多个。不管其果实色泽多么缤纷琳琅,千姿万态,按其基本色调划分的话,大体上可以划分为绿、黄、红等三大类。果实的不同色泽,是由果实细胞中不同种类的色素所决定的.按照这些色素的化学反应,大致可以归纳为如下四种:(1)Tefrapyrrol 诱导体——叶绿素(Cheorophyll)(2)Isoplanoid 诱导体——胡萝卜素类(Carotenoid)(3)Benzo—α—pyran 诱导体——花青素(Anthocyan),黄酮素类(Flavo-
Fourth, the color changes during fruit development (a) pigment types and color of fruit Currently, the world’s apple cultivars, known as up to more than 12,000. No matter how colorful and fruity the fruits are, the best of times, according to their basic colors, divided into three categories: green, yellow and red. The different color of fruit is determined by different kinds of pigments in fruit cells. According to the chemical reaction of these pigments, the following four can be summarized: (1) Tefrapyrrol inducer - Cheorophyll (2) Isoplanoid induction Carotenoid (3) Benzo-α-pyran inducer - Anthocyan, Flavo-
