哈茨木霉菌剂处理提高网纹甜瓜(Cucumis melo L. var. reticulatus Naud.)的货架期品质

Trichoderma Harzianum Enhance Shelf Life Qualities of Netted Melon (Cucumis melo L. var. reticulatus Naud.)

摘要:

该研究探讨了哈茨木霉菌剂处理对网纹甜瓜货架期品质的影响。研究在网纹甜瓜种植过程中，对甜瓜根部施用哈茨木霉菌剂4次（每次剂量为0.1 g/m2），以根部施用清水为对照组，比较果实在10 ℃冷库中贮藏第0、5、10和15 d的感官得分、颜色、质构、口味和抗氧化能力等品质特征。结果表明：哈茨木霉处理后果肉的口感甜糯，质地均一，果实最佳赏味期较对照组延长约4 d；哈茨木霉处理组果实可溶性固形物含量和Vc含量分别比对照组提高15.20%和64.58%；哈茨木霉组的ORAC值达到667.80 (µmol/L)/100 g，比对照组提高了10.05%，果实的抗氧化能力显著性提高；并且哈茨木霉处理使果皮硬度提高1.75倍，延缓果肉的软化现象，使果实更加便适于贮藏和运输。因此，种植过程中在根部追施哈茨木霉菌剂有利于提高网纹甜瓜货架期品质。

Abstract:

The effect of Trichoderma harzianum treatment on shelf life qualities of netted melon (Cucumis melo L. var. reticulatus Naud.) was evaluated. Trichoderma harzianum agent was applied to the root of the netted melon during the planting for 4 times (each time with a dose of 0.1 g/m2) with water as the control. The fruits were stored in 10 ℃ after harvest immediately. The sensory, color, taste, texture, and antioxidant capacity of samples were evaluated at 0, 5, 10 and 15 days of storage. The results showed that the pulp of melons treated by Trichoderma harzianum showed the uniform texture with lower fiber content, and the best taste period of fruits was 4 days longer than that of the control, and the soluble solid content and Vc content of fruits increased by 15.20%, and 64.58%, respectively. The ORAC value reached 667.80 (µmol/L)/100 g, which was 10.05% higher than that of the control. Moreover, Trichoderma harzianum treatment increased the hardness of peel by 1.75 times and delayed the softening of pulp which was more convenient for storage and transportation. Therefore, the application of Trichoderma harzianum during the planting of the melon improved the shelf-life qualities of the melon.
