| 摘 要：以‘夏黑’葡萄为实验材料，研究海藻精不同喷施次数处理对‘夏黑’葡萄品质的影响，确定海藻精的最佳喷施处理次数，为‘夏黑’葡萄的种植、品质提高提供参考依据。以5月开始对谢花后的幼果穗作为原材料，每隔10天喷施一次0.25%的海藻精，共喷施5次，测定单果重量，果形指数，单宁，维生素C，可溶性固形物，可滴定酸，总糖，色差值等指标，并进行单因素方差分析和相关性分析。结果表明对‘夏黑’葡萄喷施1到3次0.25%海藻精后，可以提高葡萄的单果重，纵径，横径，L*值，a*，h°，CIRG，果皮硬度，与CK组相比分别提高了5%，15%，4%，60%，59%，20%，28%，12.7%，果肉硬度降低。喷施1次时，可滴定酸，维生素C，总糖的效果最佳，分别提高了9.28%，7.03%，74.70%。当喷施2次时，单宁含量降低得最显著，较CK组降低了86.10%，糖酸比和可溶性固形物显著增高了73.37%，1.01%。单果重，横径，纵径和果肉硬度存在着显著的正相关；总糖，h°和CIRG与糖酸比存在着显著的正相关；糖酸比，总糖，单宁，横径和纵径L*呈显著正相关；糖酸比和总糖与a*，b*，c*呈现显著负相关；单宁，横径，纵径b*，c*与CIRG存在着显著的负相关。综上所述：采用0.25%海藻精喷施‘夏黑’葡萄1-3次，能提高葡萄果实的营养价值和果实品质，为‘夏黑’葡萄的优质、高产提供了理论依据和技术指导。 |

| Abstract:Using ""summer black"" grape as the experimental material, the effects of different spraying times of algal essence on the quality of ""summer black"" grape were studied, and the best spraying times of algal essence were determined to provide reference basis for the planting and quality improvement of ""summer black"" grape. Take the young fruit ears after flowering as raw materials from May, spray 0.25% seaweed essence every 10 days, a total of 5 times, measure the weight of single fruit, fruit shape index, tannin, vitamin C, soluble solids, titratable acid, total sugar, color difference value and other indicators, and conduct one-way ANOVA and correlation analysis. The results showed that after spraying 0.25% seaweed extract on ""Summer Black"" grape for 1 to 3 times, the single fruit weight, longitudinal diameter, transverse diameter, L* value, a*, h°, CIRG, peel hardness of the grape were increased by 5%, 15%, 4%, 60%, 59%, 20%, 28%, 12.7%, respectively, compared with CK group, and the flesh hardness was decreased. When sprayed once, the effect of titratable acid, vitamin C and total sugar was the best, increased by 9.28%, 7.03% and 74.70% respectively. When sprayed twice, the content of tannin decreased most significantly, which was 86.10% lower than that of CK group, and the ratio of sugar to acid and soluble solids increased 73.37% and 1.01% respectively. There was a significant positive correlation between fruit weight, transverse diameter, longitudinal diameter and flesh hardness; Total sugar, h° and CIRG have significant positive correlation with the ratio of sugar to acid; The ratio of sugar to acid, total sugar, tannin, transverse diameter and longitudinal diameter L* were significantly positively correlated; The ratio of sugar to acid and total sugar showed significant negative correlation with a*, b* and c*; Tannin, transverse diameter, longitudinal diameter b*, c* have significant negative correlation with CIRG. To sum up, applying 0.25% seaweed essence to ""summer black"" grape 1-3 times can improve the nutritional value and fruit quality of grape fruit, providing theoretical basis and technical guidance for the quality and high yield of ""summer black"" grape. |
