Tow field experiments were conducted in alkaline saline soil of newly
reclaimed lands at Abou-Mady region "North of Della" during the two successive
seasons of 2001/2002 & 2002/2003. This work aimed to study the effect of gibberellic
acid "GA3" at 30 ppm combined with paclobutrazol "PP333"at 150 ppm to modify
growth and yield parameters as well as some physiological effects of "PP333"at
heading and harvesting stages of wheat plants .The results showed that application
of "GA3" combined with "PP333"increased most significantly all the studied growth and
yield parameters as well as the contents of photosynthetic pigments, total
carbohydrates and total soluble sugars. The treatments also improved the pictures of
protein electrophoresis of wheat plants which grown in new reclaimed area.
