| Abstract | ||
| This study was conducted on the farm of college agriculture - Tikrit university as a separated Experiments on two grape cultivars: Halwani and Kamali during the growing season of 2013 to study the influence of foliar spray with Boron ، Magnesium and spraying dates to vegetative growth and yield of two grape cultivars ( vits Vinifera L.).the Study was consisted of three factors first :Three concentration of Boron (0 . 0 , 30 and 45 mg / L ) , Second :Three concentration of Magnesium( 0، 2 ، 4 gm / L) Third : Two dates of spraying, first ( 7 – 10 days before flowering and the second date was done at veraison ( beginning of berries coloring )). A factorial experiment with three replications was carried out in a randomized complete block design ( R.B.C.D) . Every treatment consisted one vine per replicate . The results indicated that the concentration of 30 and 45 mg B / L was superior upon the significantly increased at the total Acidity in berries Juice Halwani cultivar ( % 0.419 and 0.417 % respectively ) and the least significantly of an anthocyanin in this concentrations in berries Juice kamali cultivar ( 1.377 and 1.740 optical density respectively ) . The results indicated that the concentration 2 g . Mg / L was superior upon the significantly increased at total acidity in Halwani cultivar and 4 g . Mg / L kamali cultivar ( 0.425 % and 0.464 % respectively ) . and the least significantly of anthocyanin in the concentration of 2 g. Mg / L . kamali cultivar ( 1. 565 O . D ) The interaction between 30 mg . B/ L × 4 g. Mg / L × second date of spraying gave highest total sugars and T . S . S . and the least significantly of total acidity in berries Juice kamali cultivar ( 15.704 %, 16.767 %and 0.550 % respectively ) . | ||
