Pollination and Floral Ecology

This chapter examines the factors that affect the timing and patterning of flowering, as well as the effects of different flowering patterns on pollination outcomes. Plants should flower in ways that maximize their own reproductive success. The “flowering pattern” is a composite of the timing and frequency of individual flowers opening, and also of floral longevity. These phenological factors vary between and within species. Flowering phenology can influence the plant’s manipulation of its visitors in ways that should increase either or both of pollen transfer and pollen receipt. The chapter first considers the frequency of flowering and the shape of the flowering period before discussing flower longevity and flowering period. It also explores the question of how big a flower should be, how many flowers a plant should have at any one time, what determines the phenological parameters for a particular plant species, and where the flowers should be placed.
