during past few years, the cupressus arizonica has been abundantly planted in tehran, causing a significant increase of allergic diseases from the middle of winter to the beginning of spring. the aim of this study was the comparison of pollen protein content in two major varieties of c. arizonica planted in tehran, including c. arizonica var. arizonica and c. arizonica var. glabra , in order to...
BACKGROUND Sensitization to Pinales (Cupressaceae and Pinaceae) has increased dramatically in recent years. The prevalence of sensitization in different geographic areas is related to exposure to specific pollens. OBJECTIVES To investigate the prevalence of allergy to different conifer pollens, describe the characteristics of patients with such allergy, and identify the involved allergens. ...
Vegetative shoots of Arizona cypress (Cupressus arizonica Greene) were found to contain an estimated 40 to 70 mug of gibberellin-like activity per kg. Based on elution patterns of silicic acid and celite partition columns, mobilities on thin layer chromatograms and specificity of the cucumber, d-3 dwarf maize, dwarf pea, and barley half seed bioassays it was possible to determine that the tissu...
Random Amplified Polymorphic DNAs (RAPDs) data were analyzed from eighteen taxa of Cupressus from the eastern hemisphere. The following fourteen taxa were distinct in their RAPDs: Cupressus assamica (India), C. atlantica (Morocco), C. austrotibetica (Tibet), C. cashmeriana (Bhutan), C. chengiana (Sichuan), C. darjeelingensis (India), C. duclouxiana (Yunnan), C. dupreziana (Algeria), C. funebris...
This research was carried out in order to quantify throughfall (TF) and interception loss (I) and to compare the chemical composition of TF, i.e. lead (Pb) and cadmium (Cd) as well as electrical conductivity (EC) and pH beneath Pinus eldarica and Cupressus arizonica plantations and the open field rainfall. The research was accomplished in the Chitgar Forest Park, a semi-arid polluted urban area...
El objetivo de nuestra investigación es identificar los componentes químicos y evaluar in vitro, la actividad antibacteriana extractos las hojas Cupressus sempervirens L. arizonica del norte Argelia contra Pseudomonas aeruginosa ATCC 9027. La extracción se realizó macerando en disolventes polaridad creciente (cloroformo, éter petróleo metanol acuoso). Se un cribado compuestos fenólicos para una...
یکی از عوامل نامساعد برای انجام امور کشاورزی تنش باد های شدید در هر منطقه جغرافیایی به حساب می آید که با افزایش مقدار تبخیر و تعرق درافزایش مصرف آب نقش بسزایی دارد. بنابر این ضروری است با استفاده از گونه هایی که دارای رشد سریع، قدرت کنترل کافی،زیبایی و سرسبزی مناسب و ارزش اقتصادی کافی باشند با این شریط نامناسب مقابله گردد. برای این منظور در منطقه شهرستان دامغان پس از جمع آوری اطلاعات اقلیمی،طبق...
Predicting paper properties based on a limited number of measured variables can be an important tool for the industry. Mathematical models were developed to predict mechanical and optical properties from the corresponding paper density for some softwood papers using support vector machine regression with the Radial Basis Function Kernel. A dataset of different properties of paper handsheets pro...
