Common use cases Typos, corrections needed, missing information, abuse, etc Our promise PeerJ promises to address all issues as quickly and professionally as possible. In addition insects visiting the flowers of J. Discriminant analysis of floral morphological characters For the first discriminant analysis we used all populations from Southern Mexico, and the most important characters were identified to form the five principal components and to group accessions by populations.

Pollen was quantified using a stereomicroscope and the average number of pollen grains was estimated per anther and per flower. We also evaluated the genetic variability of accessions from each of nine regions in Chiapas, to identify the center of origin. Published online May Figure S2 Flowering of Jatropha curcas in its center of origin: Cluster analysis of morphological characters of flowers Two analyses of hierarchical ascendant classification dendrogram or cluster analysis were undertaken: In our study, we found some Group B accessions from Veracruz and Guatemala were genetically close to African and Asian accessions Supplementary Table 7.

Sex expression and floral diversity in Jatropha curcas: a population study in its center of origin

We found differences in the production and quality of fruits and seeds from the different reproductive systems of J. Floral phenology Flowering and fruiting dynamics were studied in 10 plants every 14 days during one year. High production of Jatropha seeds can ensure a stable and enough supply of biofuel, which will help in the battle against the climate change.
