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.

Department of Planning and Zoning
Department of Planning and Zoning Subject: Howard County Landscape Manual Updates: Recommended Street Tree List (Appendix B) and Recommended Plant List (Appendix C) - Effective July 1, 2010 To: DLD Review Staff Homebuilders Committee From: Kent Sheubrooks, Acting Chief Division of Land Development Date: July 1, 2010 Purpose: The purpose of this policy memorandum is to update the Recommended Plant Lists presently contained in the Landscape Manual. The plant lists were created for the first edition of the Manual in 1993 before information was available about invasive qualities of certain recommended plants contained in those lists (Norway Maple, Bradford Pear, etc.). Additionally, diseases and pests have made some other plants undesirable (Ash, Austrian Pine, etc.). The Howard County General Plan 2000 and subsequent environmental and community planning publications such as the Route 1 and Route 40 Manuals and the Green Neighborhood Design Guidelines have promoted the desirability of using native plants in landscape plantings. Therefore, this policy seeks to update the Recommended Plant Lists by identifying invasive plant species and disease or pest ridden plants for their removal and prohibition from further planting in Howard County and to add other available native plants which have desirable characteristics for street tree or general landscape use for inclusion on the Recommended Plant Lists. Please note that a comprehensive review of the street tree and landscape tree lists were conducted for the purpose of this update, however, only -

Abstract: Biscogniauxia granmoi, growing on Prunus padus (incl. var. pubescens = Padus asiatica) is reported from Europe and Asia, with material from Austria, Latvia, Norway, Poland, and Far Eastern Russia. It is compared with B. nummulana s. str., B. capnodes and B. simphcior.

Zusammenfassung: Biscogniauxia granmoi, die bisher ausschließlich auf Prunus padus (inkl. var pubescens = Padus asiatica) gefunden wurde, wird aufgrund von Aufsammlungen aus Europa und Asien vorgestellt. Die bisherigen Belege stammen aus Österreich, Litauen, Norwegen, Polen und dem femöstlichen Teil Rußlands. Die Unterschiede zu B. nummulana s. Str., B. capnodes und H simphaor werden diskutiert. Dieses Taxon wurde unter dem Namen "B. pruni Granmo, l.aessoe & Scheuer" nom. prov. schon von JU & al. (1998, Mycotaxon 66: 50) in ihre Revision der Gattung Biscogniauxia aufge- nommen. The genus Biscogniauxia KUNTZE (Xylariaceae) was resurrected and amended by POUZAR (1979, 1986) for a group of Xylariaceae with applanate dark stromata that MILLER (1961) treated in Hypoxylon BULL., and for a group of species with thick, discoid stromata formerly placed in Nummularia TUL. -

Prunus Spinosa
Prunus spinosa Prunus spinosa in Europe: distribution, habitat, usage and threats I. Popescu, G. Caudullo The blackthorn (Prunus spinosa L.) is a spiny, deciduous shrub which produces small, purple, edible plums. This species occurs mostly from south-central Europe up to southern Scandinavia, and eastwards to Asia Minor, growing in forest margins and open woodlands as part of Mediterranean thermophilous plant communities. It is cultivated as an ornamental plant and for fruit production, used to make jams, wine, vinegar and distillates. The blackthorn has no important threats, but it can be a natural host and potential reservoir of diseases affecting production of economically important fruits, such as apricots, plums, peaches and apples. The blackthorn, or sloe, (Prunus spinosa L.) is a spiny, deciduous shrub, growing 1-5 m tall. It forms a dense canopy with Frequency 1-4 intricate branches and numerous suckers . Secondary twigs < 25% 25% - 50% often transformed into a spine, initially velvety soft, reddish- 50% - 75% brown. The buds are globular oval, reddish-brown, more or less > 75% Chorology hairy.

Production, Pomological and Nutraceutical Properties of Apricot
1 Production, pomological and nutraceutical properties of apricot Khaled Moustafa1* and Joanna Cross2 1Editor of ArabiXiv (arabixiv.org), Paris, France 2Nigde Omer Halisdemir University, Nigde, Turkey Correspondence: [email protected] Abstract Apricot (Prunus sp.) is an important fruit crop worldwide. Despite recent advances in apricot research, much is still to be done to improve its productivity and environmental adaptability. The availability of wild apricot germplasms with economically interesting traits is a strong incentive to increase research panels toward improving its economic, environmental and nutritional characteristics. New technologies and genomic studies have generated a large amount of raw data that the mining and exploitation can help decrypt the biology of apricot and enhance its agronomic values. Here, we outline recent findings in relation to apricot production, pomological and nutraceutical properties. In particular, we retrace its origin from central Asia and the path it took to attain Europe and other production areas around the Mediterranean basin while locating it in the rosaceae family and referring to its genetic diversities and new attempts of classification. The production, nutritional, and nutraceutical importance of apricot are recapped in an easy readable and comparable way. We also highlight and discuss the effects of late frost damages on apricot production over different growth stages, from swollen buds to green fruits formation. Issues related to the length of production season and biotic and abiotic environmental challenges are also discussed with future perspective on how to lengthen the production season without compromising the fruit quality and productivity.

Investigation of Biological Peculiarities of Blumeriella Jaapii
Plant Protection Science – 2002 Investigation of Biological Peculiarities of Blumeriella jaapii A. VALIUSHKAITE Plant Protection Laboratory, Lithuanian Institute of Horticulture, LT-4335 Babtai, Kaunas District, Lithuania E-mail: [email protected] Abstract Leaf spot pathogen is characterized as a highly developed parasite after investigation of development peculiarities of the fungus in pure culture and natural conditions. The degree of correlation depended on the medium. Impact of incubation temperature on Blumeriella jaapii (Rehm) Arx growth was different. Fungi colonies formed more intensively and their diameter increased significantly under higher temperature. Optimal conditions for the disease prevalence are 15–20°C and moisture. Relative humidity and precipitation influenced maturation of ascomycetes and discharge of ascospores (r = +0.89). Microscopic analysis of leaves showed that during winter thaw, when the average temperature is about 0 ± 5ºC and relative humidity is higher than 70%, was possible to detect mature ascomycetes and conidia. It is possible to affirm that lower temperature than it was assumed is sufficient for formation of ascomycetes.
