【摘要】 以8年生苹果品种(王林、陆奥和宫滕富士)的果实为试材,采用套袋处理对黄绿品种的果实看色规律进行了研究,并采用纸层析技术分析了着色果皮的色素种类。结果表明:苹果的黄色和绿色品种具有合成花青苷的潜能,经套袋处理,着色潜能就能发挥出来,果皮可以由非红转变为红色。摘袋后,富士套袋果的花青苷含量迅速上升,经6d 即达到非套袋果水平;而黄绿品种套袋果的花青苷合成对光反应迟钝,在摘袋后16d 才开始增加。黄绿品种果皮形成红色是由于花青苷合成的增加;而套袋处理改善红色品种着色,并非由于提高花青苷含量。着色的黄绿品种果皮上的色素种类与正常红色品种果皮的大致相同。更多还原

【Abstract】 Characteristics of red color development and the kind of pigments in the red fruit skin were studied on three 8-year-old apple trees:‘Orin’,‘Mutsu’and‘Kyuuton Fuji’cul- tivars.A potential capacity of anthocyanin synthesis in the skin of non-red apple cultivars was observed,and this potential capacity could be brought into play by bagging.The skin color then turned red from yellow or green along with the increase of anthocyanin formation. It was the decrease of non-red pigments,instead of the increase of anthocyanin formation that the skin color of red cultivar was enhanced by bagging.Anthocyanin synthesis of non- red cultivars was not so susceptible for light as that of red one and only began to increase at the 16th days after bag removal.The groups of pigments were same in red skins of both non- red and red cultivars,but the specific variety and quantity of anthocyanins need be further studied.更多还原
