| Se estudió la influencia de las condiciones de cultivo (clima, riego o temporal y tipo de suelo) en la composición nutrimental de los tejidos del fruto (epicarpio, pulpa, testa y embrión) y en la remoción de nutrimentos por tejido y por tonelada de fruto fresco de los cvs. Ataulfo, Kent, Keitt y Tommy Atkins. Asimismo, en ‘Ataulfo’ y ‘Tommy Atkins’ se estudió la relación entre el contenido nutrimental en suelo, hojas, epicarpio y pulpa (materia seca) y pulpa fresca, con la calidad postcosecha. Se trabajó con árboles altamente productivos (producción superior a los 150 kg·árbol-1), seleccionados en el 2008 de los que se cosecharon frutos en madurez fisiológica. En la materia seca de cada tejido se determinó la concentración de: N, P, K, Ca, Mg, S, Fe, Cu,... |

| We carried out a comparative morphological study to evaluate the taxonomic value of seed and seedling traits of Entada polystachya and E. simplicata (Leguminosae, Mimosoideae, Mimoseae). Seeds of both species were collected from wild populations in Roraima State, Brazil. Our results show consistent quantitative and qualitative differences between these species regarding their seeds and seedlings. Testa fracture lines, funiculus impression, lens characters, radicle shape and length, and cotyledon lobes length, seedling morphology group, number of pinnae at first node, and hypocotyl length permit a straightforward distinction of E. polystachya from E. simplicata, supporting a recent treatment of the latter taxon as a distinct species, endemic to Roraima... |

| We have confirmed here that the seeds of the common bean (Phaseolus vulgaris, L.) do not support development of the bruchid Callosobruchus maculatus (F.), a pest of cowpea [Vigna unguiculata (L.) Walp] seeds. Analysis of the testa (seed coat) of the bean suggested that neither thickness nor the levels of compounds such as tannic acid, tannins, or HCN are important for the resistance. On the other hand, we have found that phaseolin (vicilin-like 7S storage globulin), detected in the testa by Western blotting and N-terminal amino acid sequencing, is detrimental to the development of C. maculatus. As for the case of other previously studied legume seeds (Canavalia ensiformis and Phaseolus lunatus) we suggest that the presence of vicilin-like proteins in the... |
