Escandón D, MLCaetano, C.M.Sánchez O., M.S.Bonilla Correa, C.R.Lascano, Carlos E.[Morfología flora, citogenética y palinología de Cratylia argentea (Desvaux) O. Kuntze. (Leguminosae)]Morfología flora, citogenética y palinología de Cratylia argentea (Desvaux) O. Kuntze. (Leguminosae)

The genus Dioscorea is considered to be one of the most difficult groups for cyto-taxonomic studies because of the large number and small size of the chromosomes. The objective of the present study was to develop an efficient method of chromosome observation by identifying the optimum time for co...

Cytological studies in Musa spp. L. are hampered by the small size and poor staining ability of the chromosomes. The aim of this experiment was to use silver nitrate as a staining agent for Musa chromosomes. The results of this study showed that silver nitrate is a useful alternative stain for cy...

In the decade since the literature on the genetics of cowpea was last reviewed by Fery (1985). Researchers have published numerous cowpea genetics studies, especially on economically important traits. Both qualitative and quantitative procedures have been utilized to study these traits, and consi...

One suspected mutant with the broad, thick and dark green leaves characteristic of tetraploid cassava was found from each of the cassava clones TMS 91934 and TMS 89/00037-17 planted out in the field. Cytological examination confirmed them as tetraploids with chromosomes number 2n=4x=72. The mutan...

Genotypic differences in the ability of immature leaf lobes and apical shoot meristems of cassava to form primary somatic embryos in P-CIM were observed (p ≤ 0.05). The mean number of apical meristems forming primary organized embryogenic structures when cultured in embryo induction medium supple...
