Abstract

Self-incompatibility is a widespread mechanism in flowering plants which prevents self-fertilization and promotes out-crossing. In this study, CYTOCHEMICAL STAINING were carried out on self- and cross-pollinated styles in PETUNIA HYBRIDA Bravo cool water mix (self-compatible) and P. hybrida Bravo purple star (self-incompatible) cultivars using Toluidine blue, Periodic-acid Schiff`s reagent (for proteins and carbohydrates staining, respectively), Sudan black and Rhodamine B hexyl ester (for lipids staining). The ultrastructure of self- and non-self pollen was also studied in the style tissues of Bravo purple star cultivar by transmission electron microscopy (TEM). Moreover, electrophoresis pattern of proteins was studied using SDS-PAGE method. The content of total protein, PHENOLIC COMPOUNDS and the activity of polyphenol oxidase (PPO) were studied spectrophotometrically. There was not considerable difference between cytochemical compounds in self- and cross-pollinated styles in both cultivars studied by CYTOCHEMICAL STAINING. Self-pollination caused to some ultra-structural changes in pollen tube and transmitting tissue of the style of this cultivar. There was a difference between electrophoresis patterns of the styles in two cultivars. Based on our results, it seems that self-pollination affects metabolic processes. These metabolic changes result in ultra-structural abnormalities in the incompatible pollen tubes and consequently self-pollen rejection in the self-incompatible cultivar Bravo purple star.
