To investigate the effect of bagging on fruit growth and quality of ‘Wentan' pummelo, the fruits were bagged with white or brown paper bags on 24th May, 26th June und 25th July. Fruit sizes were measured on each days of bagging and on September 11th after the fruits were harvested. Temperatures inside the bags in different positions of the canopy were recorded from middle to late August.
The results showed that fruit characters including size, weight, specific gravity, fruit shape, rind thickness, rind texture, sugar content and flavor were not significantly different among the treatments. In day time the temperature differences inside and outside the bags can be as high as 9℃. The differences of relative humidities were 5 to 10%. The temperatures increased inside the bags were related to the intensity of solar radiation. The growth rate of fruits which bagged earliest was lowest, but that was not significantly different among the treatments.
The color of fruit peel was analyzed on one day and one week after harvesting. L values of the fruits bugged with white bag were higher than those of the fruits bagged with brown bag or without bagging, but the a and b values were nut significantly different among the treatments. These results explained that the fruits without bagging were a little dark greener than the other treatments, but the difference was not much that it can not be visually distinguished.
