The tank cultivation of Kappaphycus alvarezii has been developed in Southern Brazil as an alternative when the sea temperature is low in winter time. This work aimed to verify if CO2 and irradiance can be used as
strategy to improve this species' tank cultivation. An initial biomass density of 21 g L-1 of seedlings were cultivated in vitro for two weeks with addition of three concentrations of CO2: 0.1 L min-1 (1CO2), 0.2 L min-1 (2CO2) and 0.3 L min-1 (3CO2) in irradiance of 50 µmol photons m-2 s-1. After this period, the CO2 addition was interrupted and plants were cultivated in higher irradiance (200 μmol photons m-2 s-1) for more two weeks. Seedlings with no CO2 addition were used as control (C). After the CO2 addition phase and high irradiance phase, the growth rate (GR), chlorophyll a and carotenoids were determined, and samples of treatments and control were observed by light and transmission electronic microscopy. Significant differences in GRs were only observed in 2CO2 and 3CO2 treatments when the phase is considered. K. alvarezii from 3CO2 showed cell wall thickening and increasing quantity of starch granules, chlorophyll a and carotenoids than the control. After the irradiance phase, control samples showed stress signs as chloroplasts alterations, decrease in starch granules quantities and an increase in total chlorophyll a and carotenoids. However, samples cultivated with CO2 showed increase in the quantity and size of the starch granules, mitochondria and Golgi complex. Such alterations suggest a cell response after CO2 addition as a strategy to prepare the plants to growth when the cultivation conditions are appropriate.
