Efectos de los aumentos de CO2 y temperatura del aire y la disponibilidad de nitrógeno sobre el metabolismo del carbono y nitrógeno en plantas de trigo (Triticum aestivum L.)

[EN]Plants have to cope with a changing environment and adapt their metabolism to such changes. Both the CO2 and temperature are key factors affecting growth and development of plants, both have increased in recent years and is predicted to do so in the future, may have important implications for agricultural productivity. Although numerous investigations on the effect of increased CO2, are scarce those who rated their interaction with high temperature. As assessment of the implications of climate change on plant response requires the recognition that interactions between several environmental factors can cause side effects that can not be predicted in a separate analysis of the same, it is recommended their joint analysis. The use of cameras in the gradient of temperature and CO2 from the air control on field crops in this study has addressed these interactions in conditions close to natural, making the temperature rise and CO2 levels, in addition to altering the nitrogen supply for the development of wheat plants. Get an overview of the integration of photosynthetic assimilation of carbon and nitrogen in the flag leaf of wheat in different stages of development-ear emergence and days after anthesis, "for his involvement in the crop growth in response to increases in CO2 and air temperature and the availability of soil nitrogen.
