| Abstract | ||
| This study was conducted in the nursery of Hort.& Land Scape Dept./ College of Agriculture and Foresory / University of Mosul during 2006 and 2007 growing seasons. Coronet peach transplants were sprayed three times aseason with four concentrations of chelated Zinc ( 0 , 10 , 20 and 30 mg.L-1.) and three leveles of Ascorbic acid ( 0 , 50 and 100 mg . L-1) , twenty days intervals between each spray and another , the first spray is done at the first week of may . Results of both seasons indicated that foliar spray of chelated Zince and Ascorbic acid each alone or both significantly increased leaves N , K , Zn and carbohydrate concentration , leaves content of total chlorophyll , transplantes leave area , transplants height , main stem diameter , number of new branches , vegetative and roots dry weight .While leaves P concentration significantly decreased with the application of chealated Zince . The treatment 30 mg .L-1+100 mg Ascorbic acid .L-1was the best,which gave the highest means of all studied parameters except P concentration in the leaves which were the highest means of it was in the transplantes which were sprayed with 100 mg Ascorbic acid .L-1 only in both seasons . | ||
