;J. N l\J d.000 A~ :J-6 '. AGRICULTURAL EXTENSION SERVICE UNIVERSITY OF MINNESOTA • The genus Pru nus contains many species and cultivars, Pru nus including both fruits and woody ornamentals. The arboretum's Prunus maacki (Amur Cherry). This small tree has bright, emphasis is on the ornamental plants. brownish-yellow bark that flakes off in papery strips. It is par Prunus americana (American Plum). This small tree furnishes ticularly attractive in winter when the stems contrast with the fruits prized for making preserves and is also an ornamental. snow. The flowers and fruits are produced in drooping racemes In early May, the trees are covered with a "snowball" bloom similar to those of our native chokecherry. This plant is ex of white flowers. If these blooms escape the spring frosts, tremely hardy and well worth growing. there will be a crop of colorful fruits in the fall. The trees Prunus maritima (Beach Plum).

Plums on the Prairies by Rick Sawatzky
Plums on the Prairies by Rick Sawatzky Information from Literature Much has been published about pollination, pollinators, pollinizers, fertilization and fruit set in text books and periodicals. The definitions are not difficult. Pollination is the movement of pollen among compatible flowering plants (cross-pollination) or from anthers to stigmas on the same plant or different plants of the same clone (self-pollination). Many plants will self-pollinate but set very few fruit; some authors consider them self- pollinating but they are definitely not self-fruitful. Self-fruitful plants (and clones) set a crop of fruit after self-pollination; some of these plants bear fruit with no seeds (parthenocarpy); others develop seeds with embryos that are genetically identical to the parent plant (apomixis); and others produce haploid seeds that develop from an unfertilized egg cell. (When haploid seeds germinate they are very weak seedlings with only half the chromosomes of normal seedlings.) Regarding temperate zone tree fruits, self-pollination and fruit set does not mean self-fertility and the development of normal seeds. Many temperate zone small fruit species (e.g. strawberries and raspberries) are self-fertile and develop maximum yields of fruit with normal seeds as the result of self-pollination by insects. Pollinators, usually insects, are vectors of pollen movement. Pollinizers are plants which provide the appropriate pollen for other plants. Fertilization is the process in which gametes from the pollen unite with egg cells in the ovary of the flower. Normal seeds are usually the result of this process. Also, the principles are easily understood. Poor fertilization in plums and other Prunus species results in a poor fruit set. -

Chinese Apricot (Prunus armeniaca ‘Chinese’) • An early-bearing variety that is ideal for difficult climates prone to late spring frosts. • Mildly fragrant, early white blooms open from pink buds. • Fruit is medium in size and sweet. Self-fertile. • 15’ height, 10’ spread; max. elevation 6,000 ft. Montmorency Cherry (Prunus cerasus ‘Montmorency’) • The finest sour or pie cherry. A heavy annual bearer, the average yield for a mature tree is 36–44 pints; self-pollinating. • A vigorous tree with upright, spreading branches and a rounded crown, it bears fruit at a young age. • Late bloom means a more dependable production of fruit; ripens in June or early July. • 15’ height and 10’ spread; max. elevation 7,500 ft. Redhaven Peach (Prunus persica ‘Redhaven’) • Developed in Michigan, this variety has become the gold standard for peaches, replacing Elberta as the most versatile and widely grown. • Regular high yields make this one of the best home garden peaches. • Vulnerable to late spring damage due to early bloom time, ripens mid-August. • 15’ height and 12’ spread; max. -
