Preliminary scope of work

Přehled současného stavu výzkumu strategií opylování orchidejí. Analýza výhod a nevýhod šálivých strategií z hlediska reprodukčního úspěchu rostliny. Publikace týkající se reprodukčního úspěchu u šálivých orchidejí by měly být prozkoumány a kriticky porovnány. Zvláštní důraz by měl být věnován vlivu velikosti květenství na reprodukční úspěch. Očekává se, že budou nastíněny cesty vpřed v tomto druhu výzkumu.

Preliminary scope of work in English

An overview of the current state of research on orchid pollination strategies. Analysis of advantages and disadvantages of deceptive strategies in terms of plant reproductive success. Publications on reproductive success of deceptive orchids should be examined and critically compared. Special emphasis should be placed on the effect of inflorescence size on reproductive success. Ways forward in this type of research are expected to be outlined.
