M. Rêgo, E. R. Rêgo, C. H. Bruckner, E.A.M. Da Silva, F. L. Finger, K. J. C. Pereira] Abstract : Pistil squashes were used to examine the growth of Passiflora edulis f. flavicarpa Deg pollen tubes in self-compatible and self-incompatible crosses. Compatible tubes typically showed a uniform layer of callose deposition in the walls and in small plugs spaced at regular intervals within the tube. Two sites of rejection were observed in incompatible crosses: the stigma and on some occasions the style, especially in anomalous crosses. In the style the inhibition of pollen-tube growth occurred in both the upper and middle parts of the transmitting tract. These findings are consistent with the hypothesis that suggests the presence of a gametophytic gene which acts in association with the sporophytic S-gene in P. edulis.
