Wild Goose Plum Prunus Hortulana ILLINOIS RANGE Tree in Flower
wild goose plum Prunus hortulana Kingdom: Plantae FEATURES Division/Phylum: Magnoliophyta Wild goose plum is a small tree that may attain a Class: Magnoliopsida height of 20 feet and a trunk diameter of eight Order: Rosales inches. Its gray or brown bark becomes scaly at maturity. Twigs are slender, red-brown and smooth. Family: Rosaceae The ovoid, red-brown buds are about one-fourth ILLINOIS STATUS inch in length. Leaves are arranged alternately along the stem. These simple, oblong to oval leaves may common, native be as much as six inches long and two inches wide. Each leaf is finely-toothed along the edges. Each tooth has a gland at its tip. The leaf is green and smooth on the upper surface and pale and sometimes hairy on the lower surface. Flowers develop in clusters, up to one inch wide. The five- petaled, white flowers appear after the leaves are partly grown. The fruit is a drupe (a seed enclosed in a hard, dry material that in turn is covered with a fleshy material). The drupe is nearly spherical and up to one inch in diameter. This red, fleshy fruit is hard, bitter and contains one seed.

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. -
Investigations of the Plum Pox Virus in Chile in the Past 20 Years
REVIEW Investigations of the Plum pox virus in Chile in the past 20 years Guido Herrera1 Sharka disease, which is caused by Plum pox virus (PPV), is one of the most serious diseases affecting stone fruit trees around the world. Identified in Bulgaria in 1931, it was restricted to the European continent until 1992 when the virus was identified in Chile. It was subsequently verified in the USA, Canada, and Argentina. After 20 years since first detecting PPV in Chile, it seems clear that the disease cannot be eradicated in spite of various measures. Considering the seriousness of this problem for the domestic industry, a series of studies have been conducted to determine the distribution and degree of transmission of the disease, its biological and molecular characterization and epidemiological aspects, etc. The available information has allowed national phytosanitary control agencies to take steps to decrease the effects of the virus. However, there is a lack of data with respect to epidemiological factors for a more accurate understanding of the performance of the virus under Chilean conditions. Key words: Sharka disease, virus, stone fruit. INTRODUCTION more precise diagnosis techniques like Polymerase Chain Reaction (PCR) (Wetzel et al., 1991; Hadidi and Levy, The first symptoms of Sharka or Pox were observed by 1994), resulting in greater knowledge about the range of farmers in southwest Bulgaria after the First World War hosts and viral strains. As well, biotechnological methods and the first scientist to describe the viral nature of the associated with genetic transformation generated plant disease was Dimitar Atanasov in 1933 (Dzhuvinov et al., varieties with characteristics of immunity to the virus 2007), calling it Sharka disease or Plum pox virus (PPV). -

Quelques Aspects Problematiques Dans La Transcription Des Toponymes Tunisiens
QUELQUES ASPECTS PROBLEMATIQUES DANS LA TRANSCRIPTION DES TOPONYMES TUNISIENS Mohsen DHIEB Professeur de géographie (cartographie) Laboratoire SYFACTE FLSH de Sfax TUNISIE [email protected] Introduction Quelle que soit le pays ou la langue d’usage, la transcription toponymique des noms de lieux géographiques sur un atlas ou un autre document cartographique en particulier ou tout autre document d’une façon générale pose problème notamment dans des pays où il n’y a pas de tradition ou de « politique » toponymique. Il en est de même pour les contrées « ouvertes » à l’extérieur et par conséquent ayant subi ou subissant encore les influences linguistiques étrangères ou alors dans des régions caractérisées par la complexité de leur situation linguistique. C’est particulièrement le cas de la Tunisie, pays méditerranéen bien « ancré » dans l’histoire, mais aussi bien ouvert à l’étranger et subissant les soubresauts de la mondialisation, et manquant par ailleurs cruellement de politique toponymique. Tout ceci malgré l’intérêt que certains acteurs aux profils différents y prêtent depuis peu, intérêt matérialisé, entre autres manifestations scientifiques, par l’organisation de deux rencontres scientifiques par la Commission du GENUING en 2005 et d’une autre août 2008 à Tunis, lors du 35ème Congrès de l’UGI. Aussi, il s’agit dans le cadre de cette présentation générale de la situation de la transcription toponymique en Tunisie, dans un premier temps, de dresser l’état des lieux, de mettre en valeur les principales difficultés rencontrées en manipulant les noms géographiques dans leurs différentes transcriptions dans un second temps. En troisième lieu, il s’agit de proposer à l’officialisation, une liste-type de toponymes (exonymes et endonymes) que l’on est en droit d’avoir par exemple sur une carte générale de Tunisie à moyenne échelle.
