Abstract
|
|
|
|
This experiment was conducted to investigate optimum bagging time and proper bagging materials to prevent spot injury and to improve the quality of Yuzu (Citrus junos L.) fruit. Most fruit spot injury occurred from late September to late October. Spot injury on fruit was reduced as much as 82∼86.1% by bagging times in 1997 and 55.4∼61.9% by using different bag types in 1998. Fruit weight, soluble solids, and acidity were not affected by bagging times or bag types. Bagging before early September with recycled Japanese phone book paper (PBP) resulted in worse coloration than control, whereas bagging on September 20 and thereafter showed similar coloration to non-bagging treatment. Grey-colored paper bags (BP) which were designed for apples and black polyester (PET) bags had low light transmittance and high air permeability, so they had lower inner temperature than PBP bags. When fruits were bagged PET and BP on September 25, fruit coloration occurred earlier than in fruit bagged with PBP or non-bagged.
