C and N content of roots and tops of wt and starch
mutants of Arabidopsis grown under different levels of nitrate
and CO2. Material from three individual plants
was pooled and used for analysis. Plants were grown under different
levels of CO2 and N nutrition during the last
16 d of growth as follows:
CLNH, growth under 35 Pa
CO2, 6 mm nitrate;
CLNL, growth under 35 Pa
CO2, 0.2 mm nitrate;
CHNH, growth under 100
Pa CO2, 6 mm nitrate; and
CHNL, growth under 100 Pa
CO2, 0.2 mm nitrate.
