Landscape scale variation in nectar amino acid and sugar composition in a Lepidoptera pollinated orchid species and its relation with fruit set

Abstract: Summary1. Understanding landscape scale variation in reproductive and pollination success is a major aim of plant population biology. A potential determinant of reproductive success that has received surprisingly little attention so far is variation in nectar chemical composition across plant individuals and populations. Using the Lepidoptera pollinated fragrant orchid (Gymnadenia conopsea) as a model species, we aimed at providing a first account of landscape scale variation in nectar amino acid and sugar com… Show more

“…A variety of long-tongued Lepidoptera species pollinate G. conopsea including diurnal and nocturnal moths and butterflies (Gustafsson 2000;Huber et al 2005;Sletvold et al 2012a). Fruit set of G. conopsea in the study area is pollen and not resource limited as supplemental hand pollinations significantly increased fruit set to nearly 100 % (Meekers et al 2012;Gijbels et al 2014).…”

“…During mid-summer G. conopsea produces one dense spike of 10-80 pale pink to intense violet flowers (Meekers et al 2012). Flowers have a long spur half filled with sucrose-dominant nectar, rich in AAs (Gijbels et al 2014) and produce scent composed of 45 volatiles, including the physiologically active benzyl acetate, eugenol and benzyl benzoate (Huber et al 2005). Each flower contains two sectile pollinia, which adhere to pollinators singly or in pairs.…”
