| Abstract | ||
| The present research worked on hand thinning and girdling processes to indicate their effects on yield and fruit quality of Dorsett golden apples var. (Malus domestica, Beck.). Results of two successive seasons 1999 and 2000 revealed that hand thinning of fruitlets and girdling of trees three weeks after fruit set significantly increased fruit yield per tree. The yielded fruits frem the treated trees comparing with the control ones were higher in weight, dimensions (aiameter and length), TSS %, TSS/acid ratio and carotene pigments in fruit skin in both seasons of study. On the other hand, such fruits were recorded lower values for firmness, acidity % in fruit juice and total chlorophylls in fru.; skin. | ||
