many powdery mildew fungi occur as anamorphic state on different host plants in guilan province, iran. the species have usually been identified as oidium spp. in order to identify teleomorphic species using anamorphic characteristics and host range, several infected plant specimens were collected from around guilan province during 2004-2011. based upon  the  results of the study 25 species were...

Background Cutleaf geranium ( Geranium dissectum L) is a weed found in cereals and grasslands. Knowledge about the germination response of weeds under various environmental conditions critical for their effective management, whereas such study has not been carried out thoroughly on this species. Objective This was to investigate effect some factors seed emergence cutleaf geranium. Methods The s...

Physiological races of powdery mildew (Podosphaera xanthii) cause different symptoms in eight melon lines. Infection by races 1, 2, and 5 was examined in different melon lines. After a compatible reaction, conidia germination, haustorium initiation from the germ tube, germ tube branching, and sporulation occurred within 12, 24, 48, and 120 h, respectively, and the conidia matured within 240 h. ...

Podosphaera is a genus of the powdery mildew fungi belonging to the tribe Cystotheceae of the Erysiphaceae. Among the host plants of Podosphaera, 86 % of hosts of the section Podosphaera and 57 % hosts of the subsection Sphaerotheca belong to the Rosaceae. In order to reconstruct the phylogeny of Podosphaera and to determine evolutionary relationships between Podosphaera and its host plants, we...

—Sceptridium dissectum, the most variable North American grapefern species, demonstrates variation in degree of blade dissection, blade color, pinnule shape, and pinnule margins. Historically, various morphologies have been included within S. dissectum. For example, Clausen’s monograph recognized five infraspecific taxa in S. dissectum, of which only the morphologies of variety dissectum and ob...

OBJECTIVE The is study examined the effects of geranium aroma on anxiety among patients with AMI. METHODS This randomized, triple-blind, placebo-controlled clinical trial recruited 80 patients with AMI through convenience sampling.
