Abstract

This investigation was carried out at the Orchard of Horticultural Research Station, El-Kassasin, Ismailia Governorate during "off" year of the two successive seasons( 2003/4 and 2004/5) on 24-year-old of Langra trees to evaluate the effect of soil drench and foliar applications of Paclobutrazol (PBZ) at 2,4 and 6 g./tree for each application method on flowering, fruit set, yield and fruit quality. The obtained results showed that all PBZ treatments advanced flowering date, improved number of perfect flowers per panicle and increased fruit set per tree as well as yield either as average number of fruit or as fruit weight (kg.) per tree. Moreover, paclobutrazol (PBZ) treatments increased fruit weight, fruit length, seed weight and pulp weight as compared with untreated (control) trees. On the other hand, fruit width, total soluble solids percentage (T.S.S.) and total acidity percentage in fruit juice showed untrue variations between treated and untreated (control) fruits. Soil drench applications were more effective on flowering, fruit set, yield and fruit quality than foliar applications. The most effective treatment was using PBZ as soil drench at 4 g./tree.
