The in vitro growth and differentiation of the alga Ulva rigida

چکیده
The in vitro growth and differentiation of the alga Ulva rigida C. Agardh have been studied. Plants grown in enriched sea water (medium II and especially medium L) have a higher chlorophyll content and regularly release a large number of reproductive cells (in 10 days). This capability does not depend on the collecting season. It has been confirmed that axenic Viva cultures grown in solution degenerate. However, if the isolated germlings were grown on semi-solid media their differentiation so metimes took place. Attachment of the germlings to the fragment of the mother plant seems also to promote differentiation. It was found that Ulva rigida could better tolerate a lower salinity than a higher one.

Nowadays, organic fertilizers play an important role in agriculture. They are progressively substituting chemical fertilizers to prevent their harmful impact on human health and the environment. They provide high yield, better quality products and a shorter period of harvesting crops. In this study, the mineral elements: primary macronutrient (N, PO3- and K+), secondary macronutrient: (Ca2+, Mg...
متن کاملPloidy Distribution of the Harmful Bloom Forming Macroalgae Ulva spp. in Narragansett Bay, Rhode Island, USA, Using Flow Cytometry Methods.
Macroalgal blooms occur worldwide and have the potential to cause severe ecological and economic damage. Narragansett Bay, RI is a eutrophic system that experiences summer macroalgal blooms composed mostly of Ulva compressa and Ulva rigida, which have biphasic life cycles with separate haploid and diploid phases. In this study, we used flow cytometry to assess ploidy levels of U. compressa and ...

Carbon physiology of a genetically identified Ulva rigida was investigated under different CO2(aq) and light levels. The study was designed to answer whether (1) light or exogenous inorganic carbon (Ci) pool is driving growth; and (2) elevated CO2(aq) concentration under ocean acidification (OA) will downregulate CAext-mediated [Formula: see text] dehydration and alter the stable carbon isotope...
