波奈亚1960年曾指出:高粱根部内皮层中二氧化硅的沉积,可能是该作物显示抗旱性的一个因素。为了解更多关于根部二氧化硅沉积与抗旱性的关系,用谷子品种进行初步研究,那些品种曾表现抗旱的和不抗旱的。谷子育种站推广的对照种科因巴托尔3号,曾以其在一般田间条件下的抗旱性著称。从另外一个品系科因巴托尔2号来的一个突变型S.I4958也曾发现同样的抗旱性。这两个品种作为供研究的抗旱类型。有10个日本品种6年来在田间条件下,比科因巴托尔3号对干旱敏感,作为不抗旱类型。研究
Pauillac pointed out in 1960 that the deposition of silica in the root lining of sorghum could be a factor in the crop’s resistance to drought. To learn more about the relationship between root deposition of silica and drought resistance, a preliminary study with millet varieties that had been drought-resistant and non-drought-resistant was performed. The control of the Baril Breeding Station, Coimbatore 3, was once known for its drought resistance under normal field conditions. A mutant S.I4958 from another strain Coimbatore 2 also found the same drought resistance. These two varieties serve as a drought-resistant type for research. Ten Japanese cultivars have been drought-sensitive over the past 6 years in field conditions than Coimbatore No. 3 as a non-drought type. the study
