摘要
为准确了解特色稻品种冷水红的农艺性状,对冷水红的株高、分蘖、叶片数、每穗粒数、粒形、千粒重等生物学性状进行了调查,并对其糙米营养成分(蛋白质、脂肪、直链淀粉、氨基酸)进行了测定。结果表明,冷水红的株高168.5 cm,分蘖数为4.2个,叶片数为13.1片,每穗粒数120粒,粒长8 mm,粒宽3.4 mm,粒厚2.2 mm,千粒重30.4g;脂肪含量、蛋白质含量、直链淀粉含量比对照丰两优4号分别高22%、42%、45%,存在显著差异;其氨基酸总含量比对照丰两优4号高49%。说明冷水红的营养成分丰富,价值高,很有开发利用前景。
This study investigated the agronomic traits of Lengshuihong, such as plant height, tillers, number of leaves, grains per spike, grain shape, 1000-grain weight and nutritional contents (protein, fat, amylose, amino acid) of the brown rice. The results showed that the plant height, tillers, number of leaves, grains per panicle, grain length, grain width, grain thickness and 1000-grain weight of Lengshuihong were 168.5 cm, 4.2, 13.1, 120, 8.0 mm, 3.4 mm, 2.2 mm, 30.4 g, respectively. The contents of fat, protein and amylase were significantly higher than the control variety Fengliangyou 4, increased by 22%, 42% and 45% respectively. The total amino acid content was 49% higher than Fengliangyou 4. It showed that Lengshuihong is rich in nutrition and high in value, and has the prospect of development and utilization.
