1. Environmental effects on pollen performance:potential consequences on gene flow
Sammanfattning : This thesis illustrates the effects of environmental factors on pollen performance and its importance on gene flow. Pollen competitive ability between the wild and cultivated species of four genera belonging to Cucurbitaceae family was compared to evaluate the evolutionary potential for selection on pollen tube growth rate.

2. Effects of Environmental Factors on maternal Choice and Gene Dispersal in Plants
Sammanfattning : Gene dispersal through pollen is affected by both abiotic and biotic environmental factors. In this study, I mainly investigated the effect of environmental factors: nutrient availability, simulated herbivory and floral morphology (flower colour), on the siring success of competing pollen donors and fitness of the resulting offspring.
