白蟠桃和黄桃果实发育的果形和色泽变化分析

Changes of fruit shape and color during fruit development of white flat peach and yellow peach

研究了早中熟白肉蟠桃‘沪蟠1号'和黄肉圆桃‘锦香'果实发育中后期的果形和色泽变化。结果表明:‘沪蟠1号'的果形变化较小,‘锦香'逐步从椭圆形变为近圆形;‘沪蟠1号'和‘锦香'红果皮L~*值、B~*值和C~*值低于同发育期的绿果皮,红果皮A~*值高于同发育期的绿果皮;‘沪蟠1号'和‘锦香'的果皮A~*值呈先下降后上升趋势,果皮B~*值与C~*值呈上升趋势;‘沪蟠1号'和‘锦香'的果肉L~*值呈先上升后下降的趋势,果肉A~*值呈上升趋势,果肉B~*值和C~*值呈下降趋势。

Field experiments with both early/mid varieties white flat peach ＇ Hupan 1＇ and yellow roundpeach ＇ Jinxiang＇ were carried out to study changes of their fruit shape and color at middle and later stages offruit development. The results showed that the fruit shape of ＇ Hupan 1 ＇ varied less while that of ＇ Jinxiang＇changed gradually from ellipsoid to near round during fruit development;The red peels＇ L ＊ , B ＊ and C＊ valueswere lower than the green peels＇ , but the red peels＇ A ＊ value was higher than the green peels＇ at the same stageduring fruit development of both ＇ Hupan 1 ＇ and ＇ Jinxiang＇ ; The peels＇ A ＊ value firstly decreased and thenincreased, while the peels＇ B ＊ and C＊ values presented a upward trend;The flesh L＊ value firstly rose and thenfell, the flesh A ＊ value presented a upward trend, but the flesh B ＊ and C ＊ values presented a downward trend.
