Leaf petiole mineral and fruit heavy metals content of different grape cultivars grown under arid environments and irrigated with treated domestic wastewater

This study was carried out during 2008 and 2009 years at the Research and Agricultural Experimental Station, King Saud University, Saudi Arabia, in order to study the comparative effect of some grapevine cultivars grown under arid environments and irrigated with treated domestic wastewater on leaf petiole mineral and fruit heavy metals content. The data indicated that the Thompson Seedless, Perlette, Des El -Anz and White Shatta had similar and lower leaf N than all other cultivars. Flame seedless had lower P. Flame seedless, Perlette and Thompson seedless had similar and lower leaf K than all other cultivars. Flame seedless and Thompson Seedless had similar and lower Ca2 than all other cultivars. Thompson Seedless had higher leaf Mg than white Shatta, Perlette, Des El-Anz, Taify, Soltany and Red Glop cultivars. In addition, Taify had significantly higher Fe than King Ruby, Des El-Anz and Soltany cultivars. Flame Seedless had significantly higher Zn and Mn than all other cultivars. The Des El-Anz, Taify, Kamaly, Soltany and White Shatta cultivars had similar and higher fruit Cu than Thompson Seedless, Flame Seedless, Red Glop and King Ruby. Moreover, Des El- Anz had higher fruit Cd than all other cultivars, except Taify, Soltany and Halawany. Fruit NO3 of Flame Seedless and Kamaly was similar and higher than all other cultivars, except Soltany and King Ruby. Kamaly, Flame Seedless and Soltany had similar and higher fruit NO2 than King Ruby, Red Glop, Perlette and Thompson Seedless.
