    摘要:

    为研究不同季节播种对大麦苗粉和籽粒营养功能成分含量的影响,探索优质两用型功能大麦高效生产技术。以48份云南大麦优良品种(系)为材料,连续两年进行四季(春、夏、秋、冬)播种,使用分光光度法和凯氏定氮法测定不同季节播种大麦苗粉与籽粒总黄酮、γ-氨基丁酸、生物碱和蛋白质含量的差异以及分析苗粉和籽粒营养功能成分间的相关性。结果表明,不同年份不同季节播种对大麦苗粉和籽粒的营养功能成分积累有显著影响,苗粉4种营养功能成分平均含量均表现为秋播>冬播>春播>夏播;籽粒表现为冬播>秋播;总体来看,苗粉营养功能成分比籽粒要高。各营养功能成分受播种季节的影响较大,呈现出播种季节>品种>品种×播种季节的趋势。初步筛选出优异两用型大麦品种(矮思秆4、腾云麦4号和云啤22号)。

    Abstract:

    In order to study the effect of sowing in different seasons on the content of nutritional functional components in barley grass powder and grains, and to explore the high-efficient production technology of high-quality dual-purpose barley, 48 barley varieties (lines) from Yunan province were sown in four seasons (spring, summer, autumn and winter) for two consecutive years. The samples harvested were subjected to measure the contents of total flavones, GABA, alkaloids and proteins by spectrophotometry and Kjeldahl method, followed by the correlation analysis on the nutrient function components between barley grass powder and grains. The results showed that samples harvested from different years and seasons showed a significant difference on the accumulation of nutritional functional components in barley grass powder and grains. The average contents of the four nutritional functional components (total flavones, GABA, alkaloids and proteins) in grass powder were autumn sowing > winter sowing > spring sowing > summer sowing. These components in grains from winter sowing season were higher than those in grains from autumn sowing season. In general, the nutritional functional components of grass powder was higher than those of the grains. The nutrient functional components were greatly affected by the sowing season, showing the trend of sowing season > varieties > varieties × sowing season. As a result, excellent dual-purpose barley varieties (Aisi 4, Tengyun 4 and Yunpi 22) were preliminarily selected.
