Abstract

The present study was carried out on On year trees of mango cultivars Ewais and Sedik during 2005/2006 and 2006/2007 seasons to study the effect of pruning severity after harvest, GA 3 and Ethrel on the total number of panicles, perfect flowers %, average number of flowering shoots, average number of vegetative shoots and yield in the next off year season. Pruning severity were as follows: no pruning, heading back (Removing half of fruiting terminal flush) and removing the intact terminal flushes, GA 3 (0, 50 and 100 ppm) and GA 3 was applied 15-21 days after pruning and Ethrel was sprayed in the first week of November. Results of mango cv. Sedik indicated that heading back and removing the intact terminal flushes have the highest value of total number of panicles, perfect flowers %, the average number of flowering shoots and yield compared to control trees while there was no significant difference among all pruning severity and the number of vegetative shoots. Removing the intact terminal flushes with Ethrel application at 500 ppm resulted in the highest value of total number of panicles, flowering shoots and yield, while using 500 ppm alone recorded the highest average of perfect flowers % but removing the terminal flushes with 100 ppm of GA 3 attained the highest number of vegetative shoots. Results of mango cv. Ewais indicated that removing the intact terminal flushes with 1000 ppm of Ethrel has recorded the highest total number of panicles, flowering shoots and yield while the highest perfect flowers % was accomplished with Ethrel at 500 ppm with heading back. The highest vegetative shoots in heading back was obtained with 100 ppm of GA 3 .
