An interesting paper from @Stephen Trueman on cross pollination in lychees/litchis (www.sciencedirect.com/science/arti...)
Strategic selection of polliniser trees can improve fruit quality of lychee, a crop that exhibits mixed-mating
Fruit trees are often planted in single-cultivar blocks that allow convenient orchard management. This planting design can reduce the opportunities fo…
