Table 4 Reproductive success and germination response from self (0 m), nearest neighbour (50 m), within forest (250 m), within pasture (700 m), and surrounding sites (3 km) pollination treatments

From: Remnant Pachira quinata pasture trees have greater opportunities to self and suffer reduced reproductive success due to inbreeding depression
