Abstract
Pineapple often sunburns as the fruits mature. At this time, the standing practice is to cover the fruits with a paper bag and tie the leaves over the fruit. This is hard work and has led to attempts to use nets to cover the entire row to reduce the overall labor. The impact on quality and size in summer pineapple fruits covered with russel nets, were studied. The study was to determine which materials are the most suitable to prevention of sunburn in pineapple. 1) Pineapple fruit is burned in sunlight in conjunction with high temperatures. Consequently, no less than 30% shade must be provided to protect the fruit from sunburn. 2) We found that using white russel nets allowed cultivation of good quality fruits. 3) On the other hand, the same nets were not suitable to prevent sunburn which occurred due to the low rate of shade provided in full, direct sunlight. 4) In contrast, blue russel nets with higher shade protection resulted in poor quality fruit. A worse side effect was that harvest efficiency declined due to the problems in judging fruit appearance under such nets. 5) Black russel nets allowed high harvest efficiency because the fruit' could be viewed through the net. Black 4 mm-mesh russel net was found to be the best material of all nets because it was inexpensive and did not damage the quality of pineapple fruits.
