Abstract
This study was undertaken to investigate the effect of pruning dates on harvesting time, yield, fruit quality and storage life of guava. The trees were grown under drip irrigation system in sandy soil under desert condition. The data revealed that, bud break, full bloom and harvest time were earlier by pruning trees at 15 Dec. or Jan. than those pruned at 15 Feb. or Mar. Also, early pruning increased the yield through increasing fruit weight, length and diameter. Fruits of trees pruned at 15 Dec. or Jan. and stored at 10 oC and 90 % R.H. for 3 weeks gave the highest percent of weight loss (17.03-18.03 %) and (16.42-17.42 %) respectively during the two seasons of study; whereas this percent was (15.27-16.45 %) and (10.23-11.65 %) in fruits from trees pruned at 15 Feb. or Mar. respectively. Also, fruit weight, firmness, V.C, acidity and total phenols gradually decreased with prolonged storage in all applications, but SSC, total sugars and SSC/acid ratio increased. Moreover, pruning application at 15 Mar. (last date) had a good effect on fruit behaviour during storage. Shelf life of fruits [held 4 days at room temperature after cold storage] have a suitable marketable condition for fruits of trees pruned at 15 Feb. or Mar. compared with fruits of trees pruned at 15 Dec. or Jan. Pruning application at 15 Mar. (last date) gave better effect in this respect.
