Abstract

Differences between cauliflower fertile and male-sterile plants and their influence on the foraging behavior for seed yield were studied Fertile plants were more attractive to bees showing bigger and perfect flowers, larger number of functional nectaries (P <0,05)) and different ultraviolet reflectance properties, allowing a more efficient pollination behaviour (corolla collection) with a consequent larger seed yield. Fertile plants were not different from male-sterile as for plants height, flowering period and flowers odour (laboratory test) (P> 0.05). The geraniol pulverization on fertile and male-sterile plants enhanced the average number of visiting bees per plant, suggesting the attainment of a more efficient pollination.
