摘要: 【目的】研究洋葱薹不同露薹长度对其产量、营养品质及抗氧化活性的影响,为洋葱薹的食用和开发利用提供参考。【方法】以洋葱薹用品种911为试验材料,采用大田种植,根据洋葱薹露出的长度,分别选取距出叶口处0、5、10、20、30 cm的洋葱薹进行采样,分析不同露薹长度对洋葱薹长、薹粗、单薹鲜重、产量,干物质、可溶性固形物、可溶性糖、可溶性蛋白、丙酮酸、总酚、总黄酮含量以及FRAP自由基清除率、DPPH自由基清除率、ABTS自由基清除率的影响。【结果】随着洋葱薹的生长,薹长的线性回归方程为y=1.096 4x+22.751 0,R2=0.987 7;薹粗的线性回归方程为y=0.135 5x+5.310 9,R2=0.985 5;单薹鲜重的线性回归方程为y=0.844 4x+4.017 1,R2=0.993 8;产量为2 813.850~11 544.000 kg/hm2。干物质含量为10.590%~12.040%,可溶性固形物含量为9.740%~14.330%,可溶性糖含量为69.530~89.160 mg/g,可溶性蛋白含量为0.870~1.170 mg/g,丙酮酸含量为0.065~0.089 mg/g,总酚含量为3.200~4.770 mg/g,总黄酮含量为0.344~0.557 mg/g;与露薹长度0 cm相比,露薹长度在20 cm时干物质、可溶性固形物、丙酮酸含量分别显著增加7.930%、13.150%、33.850%(P<0.05);可溶性蛋白含量增加3.260%;可溶性糖、总酚含量分别显著降低15.250%、24.530%(P<0.05)。FRAP自由基清除率、DPPH自由基清除率、ABTS自由基清除率在0~20 cm呈下降趋势,在20 cm处均最小。【结论】洋葱薹越短,平均隶属函数越大,综合营养品质和抗氧化能力越好。但是综合考虑洋葱薹产量、食用性、营养物质含量和抗氧化活性,洋葱露薹长20 cm时,为最适宜的采收时期,其产量可达11 544.000 kg/hm2

Abstract: 【Objective】To study the effects of different exposed scape lengths of onion scape on their yield,nutritional quality, and antioxidant activity,then provide reference for the edible and development of onion scape.【Methods】Onion scape variety 911 was used as the experimental material,and field planting was adopted. Based on the length of onion scape exposure,onion scape were selected at distances of 0,5,10,20,and 30 cm from the leaf outlet for sampling. The effects of different exposed scape lengths on onion scape length,scape diameter,fresh weight per scape,yield,and dry matter,soluble solids,soluble sugar,soluble protein,pyruvic acid,total phenolic,total flavonoid content,as well as FRAP free radical scavenging rate,DPPH free radical scavenging rate,ABTS free radical scavenging rate were analyzed.【Results】With the growth of onion scape,the linear regression equation for scape length was y=1.096 4x+22.751 0,R2=0.987 7;the linear regression equation for scape diameter was y=0.135 5x+5.310 9,R2=0.985 5;the linear regression equation for fresh weight per scape was y=0.844 4x+4.017 1,R2=0.993 8;the yield was 2 813.850~11 544.000 kg/hm2. The dry matter content ranges from 10.590% to 12.040%,the soluble solids content ranges from 9.740% to 14.330%,the soluble sugar content ranges from 69.530 to 89.160 mg/g,the soluble protein content ranges from 0.870 to 1.170 mg/g,the pyruvic acid content ranges from 0.065 to 0.089 mg/g,the total phenolic content ranges from 3.200 to 4.770 mg/g,and the total flavonoid content ranges from 0.344 to 0.557 mg/g. Compared with a scape length of 0 cm,when the scape length was 20 cm,the dry matter,soluble solids,and pyruvic acid content increase significantly by 7.930%,13.150% and 33.850%,respectively (P<0.05);The soluble protein content increased by 3.260%;The content of soluble sugar and total phenols significantly decreased by 15.250% and 24.530%,respectively(P<0.05). The FRAP free radical scavenging rate,DPPH free radical scavenging rate,and ABTS free radical scavenging rate showed a decreasing trend from 0 to 20 cm,with the lowest values observed at 20 cm.【Conclusion】The shorter the onion scape,the larger the average membership function,and the better the comprehensive nutritional quality and antioxidant capacity. However,considering the yield,edibility,nutrient content,and antioxidant activity of onion scape,the most suitable harvesting period is when the onion scape are 20 cm long,and the yield can reach 11 544.000 kg/hm2.
