Ultraestructura de la pared del grano de polen de Lycopersicum esculentum

Abstract

[ES]: La pared del polen del tomate se caracteriza en las zonas no aerturales por una ectexina de báculas muy cortas, téctum continuo y muy desarrollado coronado por una ornamentación supratectal de tipo globular. La capa basal de la ectexina es discontínua, tratandose de engrosamientos de las báculas incrustadas en la endexina, la cual presta una elevada densidad electrónica y gran cantidad de estructuras lamelares, paralelas entre si y en dirección horizontal. Finalmente la intina llega a alcanzar un grosor semejante al de la endexina.

[EN]: The tomato pollen grain wall is characterized in nonapertural zones by ectexine consisting of very short baccules, and a continuous, well developed tectum topped with supratectal globules. The ectexine foot layer is discontoinuous with baccular thickenings embedded in the endexine, which is markedly electron dense and contains numerous parallel horizontal lamellar structures (white lines). The intine is in some places as thick as the endexine.
