摘要

本試驗之目的在比較牛皮紙套袋和藍色聚乙烯（PE）套袋在‘北蕉’(Musa AAA, cavendish）果房發育和果實後熟品質上之差異。三個年期的觀察結果顯示，使用牛皮紙套袋與PE套袋對果房重量、指長、指寬與指圍均無顯著差異。牛皮紙套袋有兩年期明顯降低果指的日燒發生率，並有兩年期減少果把兩段著色發生率百分之五十。此外，還略有提升果肉總可溶性固形物及降低果肉含水量之趨勢。牛皮紙套袋提高綠熟蕉與黃熟蕉果把之L值（亮度）、綠熟蕉之a值與b值，及黃熟蕉之a值。

Effects of two types of banana bunch covers on the bunch development and post-harvest quality of cv. 'Pei-Chiao' (Musa, AAA Cavendish ) were studied for 3 cropping years No significant differences in bunch weight, finger length, finger width, and finger perimeter were found between bananas bagged with kraft paper and blue polyethylene (PE) covers kraft paper cover reduced sunburn damage and uneven degreening of banana hands by 50% in two of the three cropping years Kraft paper cover also tended to slightly increase the total soluble solids and to decrease the water content of banana pulp Kraft paper cover raised the L value (lightness) of both green mature and ripened bananas, the a and b values of green mature bananas, and the a value of ripened bananas Analysis of spectrum of simulated light absorption by the two types of bunch covers revealed that kraft paper cover blocked more blue-green and ultraviolet lights and allowed more infrared rays to pass through than blue PE cover did
