摘要: 采用溶液培养方法,对磷效率不同的燕麦品种在不同磷浓度下的生物量及磷素营养进行分析,为燕麦磷高效生理机制的研究提供依据。结果表明,随着营养液中磷浓度的增大,燕麦根、冠磷含量和生物量均增大,而根冠比和磷运转系数却降低。燕麦不同品种苗期磷效率差异评价的磷水平为0.1 mmol/L。

Abstract: The biomass and phosphorus nutrition of oats under different phosphorus concentration with different varieties were studied using the solution culture method. The results showed that: with increasing the phosphorus concentration, the biomass and phosphorus content in the root and shoot increased, while the root-shoot ratio of oats and phosphorus transport coefficient decreased. The phosphorus efficient oats varieties (genotypes) can be selected when phosphorus level was 0.1 mmol/L at seedling stage.
