Název v původním jazyce

Do nectar manipulative studies support cross-pollination hypothesis?

Popis výsledku v původním jazyce

One explanation for the widespread absence of floral nectar in many orchids is that it causes pollinators to visit fewer flowers on non-rewarding plants, resulting in more outcrossed progeny and more efficient pollen export. In the last two decades, thecross-pollination hypothesis has been tested by several experiments, in which nectar was added or removed from the flowers of non-rewarding and rewarding orchids, respectively. On the basis of the literature survey, I will summarize the effects of nectarmanipulation on male and female reproductive success of orchids, with emphasis on the incidence of self-pollination. The consequences of these results for the theory and future research will be presente
