Answer 1

Answer:

A number of fruit trees are self-incompatible, although there are isolated varieties that will successfully self-pollinate. Apples (Malus spp.), USDA zones 4 through 9; pears (Pyrus spp.), USDA zones 4 through 9; sweet cherries and plums (both Prunus spp.), USDA zones 6 through 10, are generally self-incompatible.
