[Pollinator] vanilla

[David Inouye]

Lubinsky, P., et al. (2006). "Pollination of Vanilla and evolution in 
Orchidaceae." Lindleyana 75: 926-929.

The pollination of Vanilla grandiflora by male Eulaema meriana is 
reported from the Peruvian Amazon. No scent-collection behaviour was 
observed. Vanilla is the most primitive orchid genus to demonstrate this 
interaction, and is unique among orchids for having both fragrant 
flowers and fruits.


Dam, A. R., et al. (2010). "Vanilla bicolor Lindl. (Orchidaceae) from 
the Peruvian Amazon: auto-fertilization in Vanilla and notes on floral 
phenology." Genetic Resources and Crop Evolution 57(4): 473-480.
     Minimal documentation exists for natural pollination in wild 
Vanilla spp., despite the economic importance of this genus, 
additionally commercial vanilla (V. planifolia Jacks.) is one of very 
few crops whose production depends entirely on artificial pollination. 
Flowering and fruiting phenology of Vanilla bicolor Lindl., a close 
relative of V. planifolia, was documented in a palm swamp in the 
Peruvian Amazon. V. bicolor was found to auto-fertilize via bagging 
experiments. This ecotype had an average fruit set per raceme of 42.50 ± 
2.5%. Pollen removal experiments suggest that stigmatic leak may be the 
mechanism by which auto-pollination occurs in V. bicolor.
