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. Rubberized
tape gave the highest values for all parameters measured, cellotape came
second, while polyethylene strips gave the lowest values for all
parameters measured. On the other hand, cool fan-pad plastic house
conditions resulted in the highest values of parameters measured followed
.by the lathe house, while the outdoor conditions gave the lowest values
