Karyotype characterization and comparison of three hexaploid species of Linnaeus, 1753 (Poaceae).

Chromosome morphometry and nuclear DNA content are useful data for cytotaxonomy and to understand the evolutionary history of different taxa. For the genus Linnaeus, 1753, distinct ploidy levels have been reported, occurring from diploid to duodecaploid species. The geographic distribution of species has been correlated with chromosome number and ploidy level.

Removal of methylene blue dye from aqueous solutions by adsorption using yellow passion fruit peel as adsorbent.

The removal of color from aquatic systems caused by presence of synthetic dyes is extremely important from the environmental viewpoint because most of these dyes are toxic, mutagenic and carcinogenic. In this present study, the yellow passion fruit (Passiflora edulis Sims. f.
