Abstract
Arabidopsis thaliana were grown under ambient(370 μmol·mol-1) CO2 and elevated(700 μmol·mol-1) CO2,respectively.In the present study,the floral stems were sampled for the investigation of the effects of elevated CO2 concentration on the morphological traits,anatomical features and chemical composition of the floral stems using light microscopy and Fourier transform infrared spectroscopy.It was found that elevated CO2 treatment caused significant increase on anatomical traits of the floral stems of A.thaliana,including stem size,cambium activity as well as vascular bundles area.In addition,the results of chemical composition analysis revealed that elevated CO2 treatment enhanced the content of cellulose,lignin and total soluble sugar in comparison with ambient CO2 treatment,especially cellulose and lignin.These results suggested that the floral stems of A.thaliana respond positively to elevated CO2 concentration.They have provided more structural and material foundations for the transportation of nutrients and water,to support reproductive organ.
