    C – Pollination of Fruit Trees P a g e | 3 9/2/ PEARS Pears require another cultivar for cross-pollinization. European and Asian pears will cross-pollinate if blooming at the same time. Directions for use of the following charts: 1. Select a cultivar you are interested in from the left hand column 2.   The two species of pear trees are Asian pear (Pyrus serotina) and European pear (Pyrus communis). Most pear trees need cross-pollination from nearby pollen sources of common trees, but some pear.

    Commercial importance. Seedlessness is seen as a desirable trait in edible fruit with hard seeds such as banana, pineapple, orange and nocarpy is also desirable in fruit crops that may be difficult to pollinate or fertilize, such as fig, tomato and summer dioecious species, such as persimmon, parthenocarpy increases fruit production because staminate . Summer pears include Bartlett varieties (both golden and crimson), Starkrimson and Tosca. The rest of the European-type pears fall into the winter pear group. The top pear varieties grown in Washington and Oregon are listed in the thumbnail gallery below arranged by their harvest group: Summer or Winter.

While most varieties of pear will set some fruit without cross pollination, usually they will set more and better fruit with it. Oregon State University.

Extension circular (Oregon State : Robert L. Stebbins, Walter M. Mellenthin, P. Lombard. Varieties for pollination The four main pear varieties grown in the Pacific Northwest— Bartlett, Anjou, Bosc, and Comice— will satisfactorily cross pollinate and set seed on each other.

Seckel, a minor commercial variety, is cross incompatible (will not set seeds) from Bartlett pollinizers.

Anjou can be used as a pollinizer for Seckel. Commercial pear production in Oregon is concentrated in two Considerable work was done on pear pollination throughout the western states during the 's and 's, and the information ob.

While most\ud varieties of pear will set\ud some fruit without cross pollination,\ud usually they will set more and better\ud fruit with it. Cross pollination means\ud the transfer of pollen from the\ud anthers of flowers of one variety to\ud the stigma of flowers of anothe.

Oregon. It is one of the four possible commercial poi-linizer varieties for Bartlett. Although Anjou produces well in the Willamette Valley, it usually lacks the finish and the overall quality of the same variety as grown in the Hood River and Rogue River valleysthe major winter pear districts in Oregon.

One russet sport of. The southern limit of commercial pear growing is determined by the prevalence of high winter temperatures.

The commercial pear varieties grown on the Pacific coast require a period of low temperatures (about 1, hours below 45° F (° C)) during the winter to complete their dormant period. Therefore, pears are not adapted for commercial. southern limit of commercial pear growing is determined by the prevalence of high winter temperatures.

The commercial pear varieties grown on the Pacific coast require a consider- able period of low temperatures (about 1, hours below 45° F.) during the winter so as to complete their dormant period and to start off vigorously in the spring. In commercial production, bees are introduced to pear orchards in large numbers to increase the likelihood of successful pollination.

Pear trees and pollination rely upon bees in even higher numbers than other fruits because they do not wind pollinate and the flower pollen count is low. Which Pear Trees Pollinate Each Other. Nearly all pear trees are suitable for pollinating species.

Move bees into the pear orchard when the trees are in one-third bloom. Although Anjou and Bartlett are partially self-fruitful, they should be cross-pollinated to produce heavy and regular crops. Bartlett, Comice and Hardy may set large crops of parthenocarpic fruit.

European and Asian pears will cross-pollinate if blooming at the same time. Pollination group: For the best yields, pears need pollination from a different cultivar that flowers at the same time.

If you have a large enough garden, you can plant two different cultivars (pollination partners). But most gardeners do not have this luxury, so need to rely on pollen from a neighbouring pear tree. As a general rule, pears must be cross-pollinated to produce fruit, so plan to plant two varieties; most combinations of pear varieties will work except for 'Bartlett' and 'Seckel', which don't cross-pollinate well with each other.

Out of nearly three thousand varieties, perhaps a hundred have good yields, flavor, texture, and keeping qualities.

It's all about bloom time Asian pears bloom early, and European pears bloom later, so most are not compatible simply because they aren't in bloom at the same time.

There can be cross-pollination between a late-blooming Asian pear and an early-blooming European pear. Asian pears bloom early, and European pears bloom later, so most are not compatible simply because they aren't in bloom at the same time. There can be cross-pollination between a late-blooming Asian pear and an early-blooming European pear.

Your Conference pear tree is in flowering group is self-fertile and does not need a pollination partner, but fruiting will usually be improved if there is a compatible partner of a different variety nearby.

Oregon is also a good place to grow Asian pears (Pyrus pyrifolia), which taste like a pear but have the crisp texture of an apple. Many pear trees require cross-pollination from another type of pear; Bartlett pears do not require cross-pollination so are a good variety for home growers.

Pear trees perform best on soil with a pH of 6 to 7 and in. This Anjou mutation was discovered at Eugene Euwer’s orchard near Hood River, Oregon. It produces uniform oblong-ovate fruit that is red with golden-white flesh that has a smooth texture. The fruit matures in late August to mid-September and stores well.

It is a vigorous tree that requires cross-pollination. (Bartlett is a suitable pollinator).Location: Grant Road East Wenatchee, WA United States of America.Bosc and Anjou cultivars dominate Oregon and Washington production, as they are better suited to grow in cooler climates.

In Califor acres of Bartlett represent about 75% of pear acreage in the state. (USDA ) Fruit Set. Bartlett pears can set fruit with pollination or via vegetative parthenocarpy, without differences in fruit yield.Two varieties, Waite and Magness, produce sterile pollen.

Plant Orient with them, or two other varieties with a similar pollination code letter to insure pollination of all varieties. Asian pears will probably cross-pollinate with more common Georgia varieties, but information on this is limited. As such, planting several Asian pear varieties.
