One of the most important diseases pea is caused by Pea seed-borne mosaic virus (PSbMV), which has a relatively wide host range. Since there are few varieties with resistance against virus, and spraying insecticides not very effective, determination disease pathogen in seeds important. Inoculum prepared from showing typical symptoms mild on Chenopodium amaranticolor C. quinoa , but several chlo...

Ischemia-reperfusion (IR) injury is a major cause of organ dysfunction following lung transplantation. We have recently described increased apoptosis in transplanted human lungs after graft reperfusion. However, a direct correlation between ischemic time, cell death, and posttransplant lung function has not yet been demonstrated. We hypothesized that an increased ischemic period would lead to a...

In June 1993, net photosynthetic rates, stomatal conductance and isoprene emission rates of sweetgum leaves (Liquidambar styraciflua L.) were measured at the top of the forest canopy (sun leaves) and within the canopy at a height of 8-10 m above ground level (shade leaves). Large differences in net photosynthetic rates and stomatal conductance were found between sun and shade leaves. Mean rates...

kochia is a halophyte plant and is a good source of forage for livestock under saline irrigation. in order to investigate the salinity effect on morphological and forage characteristics of kochia, an experiment was conducted. three saline waters (5.2, 10.5 and 23.1 ds m-1) and three kochia ecotypes (birjand, borujerd and sabzevar) were allocated as main and sub plots, respectively, in a split p...

the study of the potntial for using leucaena leucocephala or manihot esculentafor supplementing feeding of west african dwarf goats were carried out from november 2003 to january 2004 inthe experimental farm of the universityof dschang. twenty four west african dwarf goats, were divided in three groups of eight animals, each one 12 months old with average weight of 13.1±4.4 kg, were used in thi...

recently, tan spot disease of wheat caused by pyrenophora tritici-repentis(died.) drechsler has become very important disease in northern parts of iran and causes severe yield loss. although the anamorph of the fungus has been reported previously on infected leaves from mazandaran province (forotan et al., 1995), but there is no report on mass production of conidia in laboratory and the teleomo...

We investigated the effect of mild (34 degrees C) postischemic hypothermia on hippocampal neuronal damage in 43 rats as a function of the duration of forebrain ischemia. Two temperatures and two durations were investigated. In two normothermic groups ischemia lasted 8 (n = 15) and 12 (n = 10) minutes, respectively. In two hypothermic groups ischemia lasted 8 (n = 9) and 12 (n = 9) minutes, resp...

abstract field bindweed is an important perinial weed of agricultural crops word-wide. there are plant pathogen fungus which could cause necrotic spots on the leaves and stems of convolvulus arvensis under natural coditions. in order to evaluate the effects of weed growth stage and length of dew period on disease development causes by aletrnaria alternata and fusarium sp. two expriments were pe...
