|標題:||Changes of Mineral Nutrient Concentrations in Grapeberries during Development|
|摘要:||The objectives of this study were to investigate developmental changes in physical morphological, composition and mineral element concentrations of 'Kyoho' and 'Honey Red' grapes. The summer and winter grape berries of 'Kyoho' and 'Honey Red' grapes showed double sigmold curve of fruit width and fruit weight, it need 80-88 days for growth and the period of summer grape was shorter than winter grape. The firmness of summer grape berries was lower and 'Honey Red' showed low level in growth stage Ⅰ, and fast increase in growth stage Ⅲ. It needed 80 days for growth to reach 18。Brix in summer grape, and 8 days later in winter grape. Total titratable acidity of fruit was high at initial stage of development, and then fall rapidly while fruit maturity. During harvest, the winter grape were more acidic than summer grape. The macronutrient concentrations of berries decreased during the fruit growth.|
