Chicken red blood cells (CRBCs) are widely used as standards for DNA content determination. Cytogenetic data have shown that the Z sex chromosome is approximately twice as large as the W, so that the DNA content differs to some extent between male (ZZ) and female (ZW) chickens. Despite this fact, male and female CRBCs have been indiscriminately used in(More)
Somatic embryogenesis of Coffea arabica L. has been mainly carried out in liquid medium for clonal and mass propagation of elite lines. This in vitro system involves suspension cultures of embryogenic aggregates, with high multiplication rate and unorganized growth. These characteristics are linked to the occurrence of somaclonal variation (SV), especially(More)
Karyotype and nuclear 2C-value data are considered important in taxonomic and evolutionary approaches in Coffea. Still, new methods are needed to further support such studies, especially to determine the progenitors of Coffea arabica. In this work, new cytogenetic and flow cytometry data were used to compare Coffea arabica, Coffea canephora and Coffea(More)
The use of fungicides in maize has been more frequent due to an increase in the incidence of diseases and also the possible physiological benefits that some of these products may cause. However, some of these products (e.g., strobilurins and triazoles) may interfere with physiological processes and the formation of reproductive organs. Therefore, the effect(More)
