摘要
1985～1986年对淮北平原与长江中下游两麦区的小麦品种样品的一系列品质性状进行了测试。结果表明。淮北平原品种的籽粒角质率、千粒重、面粉湿面筋及蛋白质含量的平均值都显著大于长江中下游地区品种;籽粒客重及比重与出粉率之间呈显著正相关;籽粒角质率及比重与面粉蛋白质含量、沉淀值、粉质图主要参数以及馒头品质性状呈显著正相关;馒头品质性状与面粉蛋白质含量、沉淀值、吸水率及评价值呈显著正相关。因此,这两麦区的小麦品质改良主要目标应该是提高籽粒角质率、比重及客重,并适当提高面粉蛋白质含量及沉淀值。
The quality characteristics of 36 and 19 cultivars grown in North-Huai Plain and Mid-Lower Yangtze Region respectively were evaluated in 1985 and 1986. The results showed that the means of vitreousness, 1000 kernel weight, protein and wet gluten content of the cultivars of North-Huai Plain were significantly higher than those of Mid-Lower Yangtze Region. Test weight and specific gravity were significantly positively correlated with protein content, sedimentation value, major parameters from farinogram of flour and steamed bread quality. Steamed bread quality was significantly positively correlated with protein content, sedimentation value, water absorption and valorimeter value. It was suggested that vitreousness, test weight and specific gravity of kernel, and protein content and sedimentation value should be increased for quality improvement in these two regions.
