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.
採用溶液培養方法,對燐效率不同的燕麥品種在不同燐濃度下的生物量及燐素營養進行分析,為燕麥燐高效生理機製的研究提供依據. 結果錶明,隨著營養液中燐濃度的增大,燕麥根、冠燐含量和生物量均增大,而根冠比和燐運轉繫數卻降低. 燕麥不同品種苗期燐效率差異評價的燐水平為0.1 mmol/L.

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.
