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. -

Canada Yew to Upper Peninsula’S Ecology
The Importance of the Canada Yew to Upper Peninsula’s Ecology Canada Yew A Unique Remnant Canada Yew. Photo Courtesy of Bill Cook, Michigan State University, Bugwood.org Alger County, Michigan - The Canada yew is an evergreen shrub native to the central and eastern areas of North America. This type of conifer is also called the Canadian yew, American yew, ground-hemlock or simply yew. Its scientific name is Taxus canadensis and it thrives in ravines, riverbanks, swampy forests and on lakeshores. Mostly found north of the Ohio River, there are some rare ice age relicts as far south as the Appalachian Mountains. “Most areas of previously A sprawling shrub, northern natives called it something that translated: “that which sprawls about everywhere.” Though occasionally abundant yew in the Upper classified as a tree, most call it a shrub as it rarely exceeds three feet, Peninsula have been highly though some can grow as tall as six. The branches of the shrub are dense and spread up to six feet long. degraded or extirpated, primarily from land use Each of its cones contain a single seed partly surrounded by a bright, berry-like fruit called an aril, which is open at the end. Birds including change and overbrowsing waxwings and thrushes, among others, eat the seeds, and disperse the hard seeds through their droppings. by deer.” Dr. Steve Windels However, production of new stems or seedlings by sexual reproduction by Canada yew appears rare. Instead of a seed germinating, Canada yew reproduces predominantly by layering its stems. Arching lateral branches are pressed to the ground and take root, resulting in a spreading growth form that often produces roughly circular- shaped patches comprised of dense tangles of intertwining stems; this patchy growth form is especially evident in high-density areas with large individual stems Alison (1990). -
