| 中文摘要: |
| 本课题研究了聚-γ-谷氨酸肥料增效剂对藤稔葡萄外观和内质的影响。结果表明：经50mg/l、100 mg/l和 200 mg/l三种浓度的聚-γ-谷氨酸溶液分别进行二次灌根处理，藤稔葡萄的纵、横径有了明显的增长， 其中200mg/l的PGA处理使果实纵径呈显著性增长，与对照相比增幅为7.7%；200mg/l的PGA处理使果实可溶性固形物、Vc、可溶性蛋白含量呈极显著性增长，与对照相比增幅分别为16.2%、62.5%、28.69%。本课题还就聚-γ-谷氨酸处理藤稔葡萄后，可食率、果肉中的可滴定酸、还原糖和果皮中单宁的含量的变化规律作了分析。综合考虑，选用200mg/l浓度的PGA溶液灌根处理藤稔葡萄，可改善其果实的品质和着色质量，能促进表皮果粉的积累。 |
| 英文摘要: |
| The project was performed concerning the impact of poly-γ-glutamic acid (PGA) synergist on the external and interior quality of Fujiminori grapevines. The results indicated that both the weight and length of berry fruit were conspicuously increased by pouring root consecutively twice with processing of 50mg/l, 100mg/l and 200mg/l PGA separately, specifically, the length of berry fruit exhibited a significant difference mounting by 7.7% with the treatment of 200mg/l PGA; The content of soluble solids of Fujiminori grapevine had an increase of 16.17%, compared with the control group at the extremely significant difference level of 0.01,when 200mg/l PGA was utilized; While treating roots with 200mg/l PGA, the content of vitamin C surged by 62.5%, presenting a remarkable significant difference, meanwhile, the concentration of soluble protein augmented by 28.69%. In addition, the content and the variation law of the edible rate, the titratable acid, tannic acid of peel and the reducing sugar were analyzed. In short，the optimal treatment of 200mg/l PGA escalated the berry quality, ameliorated the coloring of fruit rind and the accumulation of powder on fruit peel in Fujiminori grapevines. |
