摘要
以‘翠冠’梨为试材,研究2次套袋中套小袋时期对梨果实内在品质及外观的影响。结果表明:总体来说,与CK相比,‘翠冠’梨成熟时,果实单果重增加;果实硬度降低;果实可溶性固形物含量与CK相比,4月22日套小袋、5月12日套大袋的A处理含量高(C黑除外);果皮厚度厚;果点密度增加;果点直径减小;果面亮度增加;套黑袋的果面绿色度极低,果面黄色度也低,套白袋的果面偏绿、偏黄。同处理套黑袋的比套白袋的单果重小,果实硬度高,可溶性固形物含量高,果皮厚度厚,果点密度增加,果点直径小,果面亮度亮,绿色度低,黄色度低。总之,A处理效果较好,与CK相比,可溶性固形物含量高,果实硬度较高,A白果实单果重大,A黑果实单果重较大。
The ‘Cuiguan ＇ pears were used as test materials,and effects of the small bagging in two times bagging on fruits internal quality and appearance were studied.The results showed that： conclusively,comparing as control （abbreviated as CK）,at ‘Cuiguan ＇ fruit maturing,mean single fruit weight increased;fruit hardness reduced;A treatment： fruit in big bag on May 12 behind it was in small bag on April 22,the soluble solids content was high （excepting for C black）;pericarp thickness increased;fruit dot density increased;fruit dot diameter decreased;fruit surface brightness improved;the fruit in internal black outer yellow bag （abbreviated as black bag ） surface was lightest green and lighter yellow,the fruit in internal white outer yellow bag （abbreviated as white bag） skin color was green bias and yellow bias.The fruit in black bag had lighter mean single fruit weight,higher fruit hardness,more soluble solids content,thicker pericarp thickness,bigger fruit dot density,smaller fruit dot diameter,brighter fruit surface brightness,lighter green and lighter yellow than the fruit in white bag between the same treatments.In all,the effect about A treatment was better： the fruit had higher soluble solids content and higher fruit hardness,meanwhile,A white fruit mean single fruit weight was the biggest and A black fruit mean single fruit weight was bigger,comparing as CK.
