Blast, caused by Magnaprthe grisea, is often an important fungal disease in the production of rice in temperate and tropical areas including Iran. To determine reaction of rice cultivars against blast disease, 40 rice genotypes from Iran and other sources from Asia were selected. Four blast isolates from different races were used to test all rice genotypes in different greenhouse tests. In bl...
this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...
the effects of agricultural information on the technical knowledge of the greenhouse owners in south khorasan province are dealt with in this study. research a descriptive-correlational methodology was ployed, and in terms of time, it was limited to the activities of the elements of knowledge and agricultural information as obtained from greenhouses during 2009. the study population consisted o...
Allelopathic effects of aqueous extract of pagoda tree and creeping jenny on five crop plants including wheat (Triticum aestivum), barley (Hordeum vuIgare), corn (Zea mays), millet (Pennisetum americanum) and chickpea (Cicer arietinum) were investigated in a series of experiments conducted at the faculty of Agriculture, SB University of Kerman, Iran. Experiments were based on RCBD with 3 replic...
damping-off disease of cucumber caused by soil-born fungi pythium aphanidermatum is one of the most destructive diseases of cucumber. in this research, the effect of three bio-fertilizers including; nitroxin, mycorrhiza and vermicompost in single and combined form on induced resistance and yield components in greenhouse cucumber (es-2862) infected with damping-off disease was investigated. thes...
Stomata of growth chamber-grown Vicia faba leaves have an enhanced CO(2) response, measured as change in stomatal aperture, compared to stomata of greenhouse-grown leaves. Reciprocal transfer experiments showed that the stomatal response to CO(2) acclimated to the growing environment. Stomata of growth chamber-grown leaves transferred to a greenhouse lost their high CO(2) sensitivity within 2-3...
Soil properties and soil-atmosphere fluxes of CO2, CH4 and N2O from four coastal wetlands were studied throughout the year, namely, native Kandelia obovata mangrove forest vs. exotic Sonneratia apetala mangrove forest, and native Cyperus malaccensis salt marsh vs. exotic Spartina alterniflora salt marsh. Soils of the four wetlands were all net sources of greenhouse gases while Sonneratia forest...
Globodera spp. eggs go through a diapause, which remains dormant until favorable hatching conditions are reached. Because of the regulatory concerns with cyst nematodes, it is often only possible to rear eggs for research in the greenhouse. However, hatch is often lower for greenhouse-produced eggs than for eggs obtained from the field. The goal of this research was to determine storage conditi...
Kerman province is the largest producer of greenhouse cucumber and tomato in Iran. This paper calculates the interest rate of return (IRR) and return period of investment (RPI) in vegetable, cut flowers and strawberry in greenhouse and compares them with vegetable grown outdoors. To do the study, a random sample of 309 farmers was selected in the province of Kerman in 2005. Results showed that ...
two separate greenhouse experiments were conducted in the greenhouse of the iranian plant protection research institute, tehran, to compare the efficacy of some acetyl coa carboxylase (accase) and acetolactase synthase (als) inhibiting herbicides in control of wild oat biotypes. in each experiment, populations were independently treated by 10 herbicides each in 12 replications. to evaluate the ...
