Temperature determines size and direction of effects of elevated CO2 and nitrogen form on yield quantity and quality of Chinese cabbage.

摘要: Rising atmospheric CO2 concentrations (e[CO2 ]) are presumed to have a significant impact on plant growth and yield also mineral nutrient composition, therefore, nutritional quality of crops vegetables. To assess the relevance these effects in future agroecosystems it is important understand how e[CO2 ] interacts with other environmental factors. In present study, we examined interactive temperature form which nitrogen supplied (nitrate or ammonium nitrate) growth, amino acid content composition Chinese cabbage (Brassica pekinensis Rupr.), crop characterised by its high value increasing for human nutrition many developing countries. Higher temperature, nitrate had positive net photosynthesis growth. A stimulating effect was only observed if (21/18 °C, day/night), an interaction N ambient (15/12 day/night). Mineral affected complex manner all three factors their interaction. These results demonstrate much depends Changes adapting fertilisation oxidation state potential counteract depletion caused ].
