Do different types of apple have the same numbers of seeds?
Seed count is related to several factors. Pollination is required for a seed to develop. It requires a minimum of 6-7 of the total possible seeds in the ovary to be pollinated for a fruit of good size to grow. The more seeds are fertilized the larger the fruit. There are five seed pockets in the apple’s ovary with space for two seeds per pocket. Orchardists check their apples by cutting crosswise, to open all pockets at once, then count the seeds to see if the tree received adequate pollination. Apples can not pollinate themselves so there must be a pollinator tree in a different variety nearby. This is why apple seeds never breed true. Healthier trees produce better fruit with more and larger seeds. Water, nutrients, pest load all factor into seed production.
