Bananas (Musa spp.), native to South East Asia, have spread worldwide and are integrated into the diets of millions of people in tropical regions. Carotenoid content varies dramatically between different banana genotypes, providing an opportunity for vitamin A biofortification. Polyploidization i...

Cowpea is a self-pollinated crop and this is encouraged by the arrangement of floral parts. However, outcrossing has been reported and frequency of occurrence could vary depending on the genotypes involved and the environment where grown. Insects have been implicated in the movement of pollen in ...

Selection among microgametophytes usually exploits variation in pollen grain germination. Studies of variation in pollen grain size in common bean (Phaseolus vulgaris L.) suggested that selection for size might lead to changes in sporophytic traits. To determine whether microgametophytic selectio...

Gu, C.Liu, Q.Z.Khan, M.A.Wu, J.Zhang, S.L.[Hetero-diploid pollen grains that represent self-compatibility are incompatible with non-self receptors in tetraploid Chinese cherry (Prunus pseudocerasus Lindl).]Hetero-diploid pollen grains that represent self-compatibility are incompatible with non-self receptors in tetraploid Chinese cherry (Prunus pseudocerasus Lindl).

Male fertility of interspecific hybrids was analysed in one F1 and two backcrossed progenies originating from a cross between Coffea canephora and Coffea heterocalyx. Male fertility was tested using pollen stainability with acetic carmine. The results showed a marked decline in fertility at the F...

Physalis peruviana L. y P. philadelphica Lam. son dos solanáceas de importancia económica para Colombia y México. Existen grandes vacíos en el conocimiento de la palinología y viabilidad polínica de estas dos especies. Por lo tanto, el objetivo del presente trabajo fue caracterizar su grano de po...

Se desarrolló una lista de descriptores y se caracterizó el polen de 156 accesiones de 121 especies del género Passiflora y dos de Dilkea. Las accesiones se obtuvieron de colectas en campo y de herbarios nacionales. Las muestras se observaron en microscopia óptica y electrónica de barrido. El pol...
