Improving Productivity and Fruit Quality of 'Crimson Seedless' Grapes

Improving Productivity and Fruit Quality of 'Crimson Seedless' Grapes. For improving fruit quality of 'Crimson Seedless' table grape the balance of vegetative and generative growth was regulated by different N and K fertilization by pruning and by fruit thinning. Dry matter sugar content acidity as well as anthocyanins stilbenes hydroxycinnamic acids proanthocyanidins and flavonols were estimated as quality parameters.
