In other species such as apricots, peaches, nectarines, quinces, the rule is the opposite - they are invariably self-fertile so you can safely plant just one example. xref Pears, plums, and cherries are a bit less widely-planted though, and you can't assume there will be others nearby, but try asking around.

Pollination also depends on having blossom to be pollinated - which is why the risk of late frosts which can damage blossom is sometimes a concern. This works for apples, pears, and most plums. 0000036732 00000 n This means that the genes present in the pip are a mix from both the mother apple and the pollen parent.

Tree is naturally small and. In this respect apples are very similar to humans - the child is a unique invididual, but inherits characteristics from its parents. 0000010551 00000 n Apple tree pollination is the key to successful fruit production.

In practice partially self-fertile varieties tend to be fully self-fertile if the spring weather is good when the blossom is open, and not self-fertile at all if the spring weather is bad. Even though some varieties are listed as self-fruitful, they will set fruit more heavily and more regularly if they are cross-pollinated. For varieties which are not self-fertile, and require a pollination partner, the partner has to be a. 0 0000001853 00000 n This is often because there is a family relationship. Pollen germination in apples works best at temperatures in the range 15C-20C / 60F-70F. However, most self-fertile varieties will produce better with another apple variety nearby. The seasons are also different from one year to the next, depending on the severity of the winter and the weather during spring.

Bramley's Seedling is a particular case in point, because it is a 'triploid' variety which means its own pollen is ineffective at pollinating other varieties - see below. Groups may be given letters or numbers, but they typically run from the earliest-flowering to the latest-flowering varieties in each species. CART 0 items | LOGIN; Adams County Nursery.
