摘要:

为探究壳寡糖(COS)对羽衣甘蓝芽苗生长的影响,为芽苗生产上壳寡糖的合理施用提供参考,以京羽一号为试验材料,在种子发芽后施用不同质量浓度COS(25,50,75,100 mg/L)溶液,观察壳寡糖对羽衣甘蓝芽苗生长指标、硫代葡萄糖苷(简称硫苷)含量及抗氧化能力的影响。结果表明,施用75 mg/L COS处理的羽衣甘蓝芽苗总酚、总黄酮、总硫苷质量以及黑芥子酶活性和DPPH自由基清除率呈现上升趋势,且与对照差异显著,较对照分别增加25.99%,17.99%,29.68%,141.88%和2.51%;100 mg/L COS处理的羽衣甘蓝芽苗的产量及总酚、总黄酮、钠和硼含量及黑芥子酶活性也得到了相应提升,且与对照差异显著,较对照分别增加了15.21%,21.29%,22.47%,15.97%,32.63%,97.71%。经相关性分析,可以得出芽苗的产量与类胡萝卜素、总酚、总黄酮含量及DPPH自由基清除率均呈显著正相关关系。综上可得,经壳寡糖处理后可提高羽衣甘蓝芽苗的产量,提升芽苗的营养品质和抗氧化能力,增加芽苗的食用价值。

Abstract:

In order to investigate the effect of chitooligosaccharides (COS) on the growth of kale sprouts and to provide a reference for the rational application of chitooligosaccharides in the production of sprouts,this study used Jingyu 1 as the test material,and applied different concentrations of COS (25,50,75,100 mg/L) to the seeds after germination to observe the effects of COS on the growth indexes,content of glucosinolates and antioxidant capacity.The results showed that total phenolics content,total flavonoids content,total glucosinolates content,myrosinase enzyme activity and DPPH free radicals scavenging rate of 75 mg/L COS-treated kale sprouts showed an upward trend,and the differences were significant with the control,with increases of 25.99%,17.99%,29.68%,141.88%,and 2.51%,respectively;the yield and total phenolics content,total flavonoids content,sodium content,boron content and myrosinase enzyme activity,of 100 mg/L COS-treated kale sprouts were also enhanced accordingly and differed significantly from the control,increasing by 15.21%,21.29%,22.47%,15.97%,32.63%,97.71%,respectively.After correlation analysis,it could be obtained that the yield of sprouted seedlings was significantly and positively correlated with the content of carotenoids,total phenolics,and total flavonoids and DPPH free radicals scavenging rate.In conclusion,chitosan treatment could increase the yield of kale sprouts,improve the nutritional quality and antioxidant capacity of sprouts,and increase the edible value of sprouts.
