Abstract

The effects of light intensities, watering times per day, CO^{2 concentrations and culture medium on the growth of Nostoc flagelliforme were studied. N. flagelliforme grew best under middle light intensity (114 μmol·m^-2·s^-1). The growth of N. flagelliforme was positively rela ted with watering times per day. Higher CO^{2 concentration(2800 μL/ L) did not significantly accelerate the growth of N. flagelliforme. Under the light intensity of 57 μmol·m^-2·s^-1, the growth of N. flagelliforme was significantly inhibited by higher CO^{2^2- concentrations. N. flagelliforme grew better when cultured with BG11 medium than that with BG11₀ medium. The lack of K⁺ and CO^{3^2- in BG11 medium did not significantly affect the growth of N. flagelliforme in the experiment.}}}}
