Summary

In order to establish if wild asparagus Asparagus prostratus fruit-set is limited by pollination, experiments were undertaken to compare natural insect pollination with hand pollination at four colonies (one in west Wales and three in Cornwall, south-west England). Hand pollination was successful in increasing fruit-set relative to natural pollination in three of the four populations. Overall, hand pollination resulted in a 4.5-fold higher fruit-set (54 fruits) compared to fruit-set of naturally pollinated plants (12 fruits).
