摘要:

【目的】分析鲜食糯玉米籽粒授粉后不同时期主要营养成分的动态变化。【方法】以10个鲜食糯玉米品种为材料,采用完全随机区组设计,分析灌浆期中籽粒蔗糖、可溶性糖、淀粉、蛋白质含量变化规律及营养品质与品尝感官的相关性。【结果】糯玉米籽粒中蔗糖和可溶性糖含量均为单峰变化曲线,蛋白质含量始终保持上升趋势,饲料玉米中粗蛋白含量与粗脂肪含量始终保持上升趋势,而糯玉米籽粒中可溶性糖、蔗糖、蛋白质含量呈下降的趋势,淀粉含量呈上升的趋势,糯玉米籽粒中可溶性糖、蔗糖、蛋白质含量持续下降是糯玉米特有的营养品质变化规律,各品种灌浆后期蛋白质含量变化幅度较小。鲜食糯玉米的籽粒营养成分中蒸煮品质与蔗糖含量(0.459 9**)、可溶性总糖含量(0.472 8**)之间呈极显著正相关,蔗糖含量与蛋白质含量(0.794 9**)呈极显著正相关,蔗糖含量与可溶性总糖含量(0.564 2**)之间呈极显著正相关;鲜食糯玉米淀粉含量与蔗糖含量呈极显著负相关(-0.427 5**)。【结论】10个糯玉米品种的蒸煮品质与蔗糖、可溶性糖的相关性较高,蒸煮品质与可溶性糖、蔗糖的浓度呈正相关,蒸煮品质与营养成分相关性对定向选育糯玉米新品种具有一定指导作用。

Abstract:

【Objective】 To clarify the dynamic changes in the main nutritional components of fresh glutinous corn grains at different stages after pollination. 【Methods】 Using 10 glutinous corn varieties as materials, a completely randomized block design was used to analyze the changes in grain sucrose, soluble sugar, starch, and protein content during the filling period, as well as the correlation between nutritional quality and quality taste. 【Results】 The results showed that the content of sucrose and soluble sugar in sweet corn grains were unimodal change curves, the protein content always maintained an increasing trend, and the crude protein content and crude fat content in feed corn always maintained an increasing trend. The results also showed that the soluble sugar, sucrose, and protein content in glutinous corn grains showed a downward trend, while the starch content showed an upward trend. Therefore, the continuous decrease in soluble sugar, sucrose, and protein content in glutinous corn grains was a unique nutritional change pattern. The decline rate was relatively fast in the early stage of filling, and gradually slowed down in the middle and later stages. The protein content of each variety changed slightly in the later stage of filling. There was a highly significant positive correlation between cooking quality, sucrose content (0.459,9**) and total soluble sugar content (0.472,8**); sucrose content and protein content (0.794,9**); sucrose content and total soluble sugar content (0.564,2**); there was a highly significant negative correlation between starch content and sucrose content in fresh glutinous corn (-0.427,5**). 【Conclusion】 The correlation coefficient between cooking quality and sucrose and soluble sugar of 10 glutinous maize varieties is higher, indicating that cooking quality is positively correlated with the concentration of soluble sugar and sucrose. The higher the preference for sweet and glutinous maize varieties, the more directional breeding of new varieties with nutrition and taste.
