Evaluation of singlenode plantlets as a model system for grapevine trunk diseases

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

fungal pathogens associated with grapevine trunk diseases in iran

during 2004–2007 various own rooted vineyards were inspected to study the fungi associated with vine trunk diseases in iran. samples from declining vines showing yellowing and reduced growth and different symptoms in wood, including browning of the wood, necrosis, brown and black streaking and white rot were collected. fungal isolations were made from affected tissues onto malt extract agar (me...

Phytotoxins Produced by Fungi Associated with Grapevine Trunk Diseases

Up to 60 species of fungi in the Botryosphaeriaceae family, genera Cadophora, Cryptovalsa, Cylindrocarpon, Diatrype, Diatrypella, Eutypa, Eutypella, Fomitiporella, Fomitiporia, Inocutis, Phaeoacremonium and Phaeomoniella have been isolated from decline-affected grapevines all around the World. The main grapevine trunk diseases of mature vines are Eutypa dieback, the esca complex and cankers cau...

Designing a Model for Evaluation of Universities System

Control and evaluation are major secrets of an organization's survival.Universities, as research and educational organizations, need to be evaluated in order to survive. The results of educational activities encompass a vast spectrum including the graduates, researchers and planners, scientific publications, as well as satisfaction of students, parents, profossors and staff (Ramsden, 1996).Th...
