| Abstract | ||
| A field experiment was carried out during 2015/2016 and 2016/2017 seasons on Egyptian lime trees (Citrus aurantifolia) on orchard located at Al-kamal region, Governorate , Egypt . In this study, the effects of Naphthalene acetic acid (NAA) at different concentrations (0.50, 0.75, 1 .00, 1.25 1.50 %) for suckers growth andimprove fruit quality of lime trees. As a result of the study, spraying NAA highly decreased trunk sprouts. However, the highest concentration (1.50%) recorded the lowest values of number, weight, and length of Suckers during the two growing seasonscompared with the control and removal treatments. In addition, it enhanced vegetative growth parameters as leaf area and chlorophyll content in the leaves in both seasons. Moreover, Spraying NAA at 1.00%achieved the highest values of fruit weight, length, diameter, yield/tree and fruit Acidity % in the two seasons, respectively. Furthermore, NAA at 1.25%increased fruit juice %, TSS % and Ascorbic acid content in fruit juice in the two seasons of study. Peel thickness was reduced as a result of NAA at 1.50%. | ||
