Effect of Wrapping Materials on Budding of Grapefruit (Citrus paradisi Macf.) cv. “Redblush”

Abstract

This experiment was conducted in the orchard of the College of Agricultural Studies Sudan University of Science and Technology, Shambat, during the last week of July to October 2006. The aim of this work was to evaluate the effect of different wrapping tapes on budding efficiency and scion growth and development of grapefruit. Buds of grapefruit (Citrus paradisi Macf.) culivar “Redblush” were budded on 12 month old sour orange (Citrus aurantium L.)seedlings. The buds were attached to the rootstock using one of these wrapping tapes as treatments : rubberized, cellotape, cellophane, plastic and electrical tapes These treatments were conducted under 3 different environmental conditions namely cool fan-pad plastic house, lathe house and outdoor. ‫.‪plants‬‬ ‫‪Parameters measured at the end of the experiment, which included‬‬ ‫.‪percent of bud-take, shoot length and number of leaves‬‬ ‫‪The results showed that the tape type material affected significantly‬‬ ‫‪the percent of bud-take, shoot length and number of leaves.
