摘要
对105份高粱种质进行了田间鸟害调查以及鸟害与高粱性状间的相关性研究.结果表明,中紧穗型、籽粒单宁含量低、生育期短的品种穗部受害严重;中散和散穗型、籽粒深色的高单宁含量材料以及生育期长的材料受害较轻;芒长、颖壳包被度等性状与鸟害间有一定的关系,长芒及籽粒颖壳包被度大在一定程度上可以减轻鸟害.不同类型品种的受害情况不同,我国地方品种和育成品种受害比例较低,说明地方品种在长期种植的过程中,自然选择和高粱抗鸟害育种中的人工选择起了一定作用;而国外品种白籽粒材料较多,单宁含量相对少,受鸟害比例较高.
Abstract
One hundred and five sorghum germplasms were investigated and analyzed on correlation among traits of sorghum and bird.The result showed that sorghum germplasms of semi-compact panicle type,low content of tannin in grain and short growth period were seriously damaged.Sorghum germplasms of semi-compact and drooping panicle type,high content of tannin in dark color grain and long growth period were not serious.These sorghum germplasms of the characteristics panicle were more suitable for foraging by sparrows.Besides,awn length and glume covering were correlated with damaging bird.In a word,the long awn and the large glume covering could alleviate damaging bird.The damaged condition of different sorghum varieties was also different.In our country,the damaging proportion of local varieties and varieties bred were relatively low,which showed natural selection of long-term planting landraces and artificial selection of sorghum breeding in the anti-bird played a certain role.The materials of white color grain were higher percentage in foreign varieties,these were lower content of tannin in grain and proportion of the damaging bird was higher.
