levando a planta à alogamia. Em plantas alógamas, é desejável que um grande número de grãos de pólen (GP) sejam hábeis à fertilização, pois cada um leva. alogamia entre dos variedades de frijol común en Fraijanes y Alajuela todas las plantas de PAN 68 en las cinco hileras próximas al bloque central. ALOGAMIA.- Cruzamiento natural en las plantas, que origina la formación de las poblaciones heterocigóticas y panmícticas debido a la polinización al azar.

A nivel molecular existen tres sistemas adecuadamente caracterizados: The existence of SI in economically important plants may be aloggamia important, being very positive in some cases or a burden in others, depending on the plant part harvested vegetative or reproductive and its mode of reproduction, sexual or asexual.

Floral display, assessed as the total number of fowers per plantsa plant, was estimated by inconspicuously tagging plants at the vegetative stage and counting the total number of fowers produced by such plants at the end of the fowering season.

Molecular aspects of the self-incompatibility systems of Brassica and Nicotiana. SIS may be homomorphic, when there are no floral modifications related to the SI process, or heteromorphic, when floral modifications occur together with the SI process.

Thereafter, the most likely shortcut to break away from the ecological and evolutionary limitations imposed by consistent sexual reproductive failures is the adoption of pollinator-independent fruit production i.

The results of these treatments were recorded by checking the ratio of fruits produced per crossed fower when the ovaries were ripe, prior to seed dispersal. In fact, fruiting success attained by G.

Nevertheless, increaments in foral display in a per-individual basis did not translate into an increase in fruit set, thus indicating that pollinators did not act as selective agents on this trait for the period herein assessed.
