The soil type was andosol with pH 5. The distribution of the groups revealed a distinct geographic cline. The only apomictic fruit had a high fresh weight, which contrasted with a low dhiapas fresh weight, due to its thick endocarp. Case Studies from the Drylands of Latin America. Centro was the most diverse population. Analysis of seed phorbol-ester and curcin content together with genetic diversity in multiple provenances of Jatropha curcas L.

In vitro mass multiplication of Jatropha Jatropha curcas L. To estimate the production of pollen and ovules, inflorescences were collected from other 10 plants with closed flowers, and 20 Female Flowers FF and 20 Male Flowers FM were randomly selected.

Principal component 2 C2 A accounted for Our data chiaps that the efficient pollinating bees have oligolectic or monolectic behavior, at least during the season studied. The mean percentage of the missing data of RBIP markers was 1. The DNA samples were diluted to a final concentration of 0.

Genetic Diversity in Jatropha curcas Populations in the State of Chiapas , Mexico

By a graph of centroids the relationship between the six populations was shown; the results were similar to the observed by grouping based on floral characters variation, as Guatemala was one of the most diverse populations in both studies, in addition to the close relationship in which the populations of the center and coast of Chiapas were grouped.


Does epigenetic polymorphism contribute to phenotypic variances in Jatropha curcas L.?

This article has been cited by other articles in PMC. Phenotypic diversity of Jatropha curcas L. Chiapas accessions were further sub-classified into those from six regions [Centro 14Frailesca 8Fronteriza 3Sierra 4Selva 2and Soconusco 26 ]. Differences between H E and H O are caused by inbreeding often as results of selection or the small population size.

Julieta Grajales-Conesa performed the experiments, wrote the paper. Note that they found that SNPs of some genes were mostly in Mexican accessions in the same paper. Table 3 Chipaas analysis of flower traits of Jatropha curcas from Meso-America.
