T1 Cytometric Method for Determining the Potential Growth Rate of Phytoplankton on the Mitotic Index JF International Journal on Algae JO IJA YR 2015 FD 2015-03-12 VO 17 IS 1 SP 94 OP 106 K1 flow cytometry K1 microalgae K1 phytoplankton K1 mitotic index K1 growth rate K1 SYBR Green I AB The effect of light intensity and light-dark cycles (12 : 12) on the percentage of cells with diploid DNA in mono-specific cultures of microalgae Phaeodactylum tricornutum Bohlin, Nitzschia sp. 3, Prorocentrum pusillum Dodge, P. cordatum Schiller, and Isochrysis galbana Schiller was studied by flow cytometry. It was shown that the proportion of cells in the G2 phase was significantly higher under high-intensity lighting. In all species a strong correlation (r2 > 0.98) was revealed between the potential growth rate of algae determined by the mitotic index, and their specific production, as measured by the increase in number. Flow cytometry was use for cell cycle analysis and evaluation of potential growth rates of picophytoplankton and nanophytoplankton of the Black Sea. At three stations in Sevastopol and Quarantine bays potential growth rates of pico-and nanophytoplankton in the surface layer was 0.2−1.0 d−1 (year-round sampling in 2010 at 3 stations, a total of 120 samples). Maximum values of this parameter corresponded to the number of annual peaks of the phytoplankton number.
