Investigation and Analysis on Colored Characters of Grape Varieties
Abstract： Grape (Vitis vinifera l.) is one of the most important fruit trees in the world, and the study of the color of grape skins is of great significance to the selection of parental breeding in hybridization. In this study, 217 cultivars of table grapes, 70 cultivars of wine grapes and 8 wild grapes were randomly selected for fruit coloring traits. The results showed that there were six kinds of fruit color in these grape varieties: greenish yellow, yellowish green, pink, mauve, dark purple and bluish violet. Table grapes and wine grapes coloring mainly concentrated in July, and early July in particular; the average coloring time of these surveyed grape cultivars was 18.9d, and the Vitis vinifera L. was longer than the V.vinifera-The American species of Euvitis. Table grapes were also longer than wine grapes. The increase in the number of colored fruit grains on the shaded grapes is shown as "slow - fast - slow" curve, and this phenomenon was also presented to early, medium, and late ripening cultivars, but the proportion of three stages on the “S” curve had some differences. There were also some differences in the first shading parts of different species of grain and berry. 45% grapes were shoulder colored first, and in the most berry the first colored part was the berry tip. Water spray test results show that the water will promote the majority of grape varieties of fruit coloring process, but a small part of the grape varieties are not affected.
