Self‐incompatibility limits sexual reproduction rather than environmental conditions in an invasive water primrose

ABSTRACT: Abstract Fruit‐set and seed‐set depend on environmental conditions and reproductive systems. They are important components of sexual reproductive success in plants. They also control the ecological success and adaptation of invasive plants within their non‐native ecosystems. We studied which factors bring about fruit‐set and seed‐set in invasive populations of the aquatic plant Ludwigia grandiflora subsp. hexapetala. We analyzed fruit set and seed set in 37 populations growing under variable climatic conditions in Western Europe. Sub‐samples of seven fruitful and fruitless populations were grown in common controlled conditions. We carried out self‐ and cross‐pollinations, and measured the floral morphometry. Environmental conditions did not affect fruit‐set and seed‐set in‐situ and in comm
