Abstract An alternative method for improving the production of habanero chili is the tissue culture technique; however, the gelling agent, the high salt and sucrose concentrations used in the culture media raise production costs and limit the adaptation of the regenerated plants to greenhouse or field conditions. In this study, the effect of the substrates perlite-coconut fiber, coconut fiber-volcanic rock, vermiculite-perlite, and perlite-volcanic rock in conjunction with various culture media in in vitro plant regeneration from embryos was evaluated. The differentiation of adventitious shoots on substrates was scarcely observed or non-existent. Inducing the formation of shoots on… More >

Abstract An experiment was conducted to evaluate the effect of different culture media on the productive response and proximate composition of microalgae, Nannochloropsis oculata, and the subsequent effect of such microalgae on the productive response and proximate composition of the rotifer Brachionus rotundiformis. Microalgae were cultured in different media: Guillard F/2 (control), an agricultural fertilizer, and an aquacultural fertilizer. Thereafter, such microalgae were used to feed rotifers. A better productive response was observed when microalgae were cultured in the agricultural fertilizer. In addition, the chemical proximate composition of microalgae was influenced by the type of culture medium used. More >
