Root Vigor and Kinetic Characteristics and Nitrogen Use Efficiencies of Different Potato (Solanum tuberosum L.) Cultivars
J. Agr. Sci. Tech
In the present study, the root vigor and kinetic characteristics of nitrogen absorption in potato cultivars was investigated through sand cultivation and pot tests with nutrient solution. Four cultivars of potatoes, namely, Feiwuruita, Yunshu301, Liangshu97, and Chuanyu56 were grown in nutrient solution matrix cultures. The result showed that: (1) Nitrogen uptake rates differed significantly among cultivars with different nitrogen efficiencies; (2) cultivars with High nitrogen-utilization-ratefatcat:dtlilnjlkbfx3nfc3x3kpt3s74
