PHYSIOLOGICAL STUDIES TO CONTROL POMEGRANATE FRUIT DISORDERS
SALAH EL-DIN MOHAMED ALY EL-MASRY;
Abstract
Three main factors are believed to be responsible for considerable
decline in Manfalouty pomegranate production in Upper Egypt. Fruit cracking, sunburn and pale color of fruit skin (discoloration) are serious fruit disorders which render fruits unsuitable for the local market or for exporting.
Accordingly, three field experiments were carried out during three successive growing seasons of 1991, 1992 and 1993, in two pomegranate orchards. The first is located at the Experimental Station of Assiut University (clay soil) and the second is located at El-Ghorieb Experimental Station where the soil is sandy calcareous.
The frrst experiment:
The main objective of this trial is to mmumze fruit cracking throughout certain treatments of soil application of ZnS04 as follows: 1) Untreated control trees; 2) 400 g ZnS04 / tree/year applied on June; 3) 400 g/tree/year on August; 4) 800 g/tree/year on June; 5) 800 g/tree/year on August. These treatments extended for 3 seasons. During 1992 and 1993 seasons two additional treatments were applied either on clay or sandy calcareous soil. Such two treatments were; 1) soil application of 800 g ZnS04 /tree divided in two equal doses and applied on June and August, and
2) 1600 g/tree divided in two equal doses and applied on June and August.
