Effect of Pruning and Branch Thining on Some Characters of Vegetative Growth of Fig( Ficus carica L.) , cv. Aswad Diala ( Ficus carica L.)
Abstract
An experiment was conducted in a private orchard at Abbasyia , Najaf
Governorate during the growing season of 2010 on fig cv. Aswad Diala . The

removal grown at wood aged more than two years and unfruitful branches that grown
at wood aged one year old .Results showed that pruning treatments and branches
removal treatments and their interactions caused a significant increase in leaf aria and
its total chlorophyll contents , GA3 , IAA , Zeatin, Methoxsalen in leaves and longer,
dimeter and number of branches and number of node ,length of internodes and total
carbohydrates percentage , N , C/ N in branches, compared to control treatment.
There were a significant effect between treatment . Treatment of ( pruning of branches
at aged one year old with percentage 50% + unfruitful branches removal grown on
