Effects of Previous Pollination and Stylar Ethylene on Pollen Tube Growth in Petunia hybrida Styles.
The effect of ethylene on the growth rate of pollen tubes in styles of Petunia hybrida was examined. Apart from its strong inhibition of pollination-induced ethylene synthesis, aminoethoxyvinylglycine, placed on the stigma, did not impede tube growth. The inhibitors of the action of ethylene, silver thiosulfate and 2,5-norbornadiene, were similarly ineffective. Application of the ethylene precu...
متن کاملStylar peroxidase and incompatibility reactions in Petunia hybrida.
Self-, cross- and non-pollinated styles of Petunia hybrida were treated with 3-3'-diaminobenzidine for the ultrastructural localization of peroxidase activity. Wall peroxidases were absent in cross-pollinated styles, but they were detectable as an osmiophilic deposit on the cell walls of the outer portion of the transmitting tissue in self- and non-pollinated styles. The cell layer showing pero...
متن کاملPollen tube development in Petunia hybrida following compatible and incompatible intraspecific matings.
Pollen tubes formed following compatible and incompatible intraspecific matings in Petunia have been examined with light and electron microscopes. Compatible and incompatible tubes develop in an identical fashion on the stigma but, on entry into the top 1 mm of the stylar transmitting tissue changes occur both to the cytology of the tubes and their rates of growth. The early cytological changes...
متن کاملEffects of Glycerol and Salicylic Acid on Freezing Tolerance of Iranian Petunia (Petunia hybrida L.)
The aim of this study was to investigate the effects of glycerol (GL) and salicylic acid (SA) on freezing tolerance of Iranian Petunia (Petunia hybrida). For this purpose, a factorial experiment based on completely randomized design with three replications was conducted under controlled conditions. The first factor was temperature (0 and -4 °C) and the second factor was spraying with anti-stres...
