because the female and parts of papaya plant are on two different plants so a alone plant fails to pollinate and fruit doesnot develop
To start with the Papaya is not a tree but that has nothing to do with lonliness and bearing fruit. The Papaya like most plants and animals reproduces sexually but as well as there being male plants and female plants there are also hermaphrodite (having both sexes). Where Papaya grow naturally, rather than being farmed, it is just luck if there is a plant of the opposite sex near enough for insect polination. If not no fruit are formed so no further plants grow and lonely pant remains lonely. Hermaphrodite Papaya plants self-fertilize so will fruit and a lonely Hermaphrodite would soone be joined by others. Nearly 70% of the fruit of hermaphrodite trees are themselves hermaphrodite. Commercial growers allow some fruit to grow and using genetic testing can determine which are hermaphrodite and will only plant these in the fields - making the fertilisation simpler and more effective. So - lonely Papaya plants often don't have fruit but, where it matters this situation can be corrected. Beano UK
