Effect of some sitofex.and cultar treatments on yield and quality of roumi red grapes [electronic resource].

Includes references.

In 1998 and 1999, bunches on 30 - years - old Roumi Red grapevines were sprayed at full bloom or at fruit set with 1 , 3 or' 5 ppm Sitofex to relieve the heavy flower and fruitlets shedding from the bunches. The traditional application of Cultar (250 ppm at pre ¬bloom stage) and untreated control bunches were also involved. The bunches showed clear response to all tested treatments; obvious increments were obtained in bunch weight, yield per vine, number of berries I bunch, bunch width, bunch compactness, 100 - berry weight, berry length and berry diameter. by most Sitofex and Cultar treatments in comparison with the control in the two experimental seasons . The most promising treatments were Sitofex 3 and 5 ppm at fruit set. Key words : Roumi Red grapevines, full bloom, fruit set, number of berries I bunch, bunch weight, yield per vine couleur.
