EFFECT OF CYCOCEL (CCC) ON SHEDDING OF BUDS, FLOWERS AND IMMATURE PODS IN VICIA FABA PLANTS

Abstract

The effect of cycocel (CCC) in regulating shedding in Vicia faba plants were investigated Abscission percentage in buds, flowers and immature pods was found to be 92.5 and 89.5% for Giza '2" and Giza '402" respectively, whereas CCC-treatments at 100,250 and 500 ppm as seed soaking reduced such drop to 6.2 and 3.2% below the normal, specially at 100 and 250 pmm CCC applications, for variety Giza '2' and Giza "204' respectively. In this investigation, CCC-application resulied in geting better results, i now, in reducing such drop and increasing broad bean yield. Although the reduction percentage was low, it is considered as a successful atternpt having regard to the fact that the final yield in natural conditions after shedding process is between 7.5 and 10.5%, whereas the total loss in the yield was 92.5 and 89.5% for variety Giza '2 and Giza '402' respectively.
