英文摘要	In farming projects, environmental variations can affect growth, productivity, survival, and fertility, as well as the quality of the produced biomass. This is why estuarine algae could be a good alternative for developing aquaculture ventures in a global climate change scenario since they can develop in highly fluctuating environments with large temperature and salinity fluctuations and low light penetrability. In this study, the best culture conditions (i.e., temperature; nutrients with Provasoli culture medium (PES) and PES + Kelpak (R), a commercial biostimulant based on algae; salinity and photon flux) for the growth and fertility of gametophytes and sporophytes of the estuarine alga Punctaria latifolia were evaluated. Gametophytes and sporophytes of P. latifolia showed good tolerance to a wide range of abiotic variables. Under culture conditions, both stages presented the highest growth at intermediate to high temperatures (16-20 degree celsius) and intermediate to high salinity (27.5 - 35 psu). However, gametophytes grew better at intermediate to high nutrient concentrations of PES and PES + Kelpak (R) and low and high light intensity (5-35 mu mol photons m(-2) s(-1)), whereas sporophytes grew better at intermediate to low nutrients of PES and PES + Kelpak (R) and low light intensity (5 mu mol photons m(-2) s(-1)). Punctaria latifolia would be a potentially cultivable alternative due to its broad tolerance to unfavorable environmental conditions in the climatic change we face.
