Bacterial wilt caused by Ralstonia solanacearum is one of the most destructive diseases which negatively affect the tomato production worldwide. Considering the importance of the disease, using biological control agents could be effective approaches in reducing the damage of the pathogen. Tomato samples of suspected bacterial wilt disease were gathered from different regions of East Azarbayjan....
Greenhouse tomato growers in the United States have few products available for chemical control of plant pathogens. Biological control of soilborne plant pathogens by antagonistic microorganisms is a potential alternative to the use of chemical pesticides during greenhouse production. Biological control experiments were conducted to test the effects of commercial and noncommercial strains of Tr...
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
The use of biological control agents could be a non-chemical alternative for management of Meloidogyne spp. [root-knot nematodes (RKN)], the most damaging plant-parasitic nematodes for horticultural crops worldwide. Pochonia chlamydosporia is a fungal parasite of RKN eggs that can colonize endophytically roots of several cultivated plant species, but in field applications the fungus shows a low...
some researches made in the field of agency problem issue, deal with the role of control systems regarding owners and managers. in this research the relationship between the two control mechanisms, namely the voluntary disclosure (external control mechanism) and outside directors (internal control mechanism), which are reductive of agency problems, has been studied. for this reason, a sample ...
systemic induction of peroxidase and polyphenoloxidase in tomato roots and stem followed by application of split root system method was investigated. root system of tomato seedling in the sixth growth stage were divided in two equal sections after washing and replanted in two adjacent pots and then inoculated with nematode and fungus as fallowing treatments. the second treatment was inoculation...
Millet, milo, soybean, crotalaria, and Norman pigeon pea were used in conjunction with clean fallow and a nematicide (fensulfothion) for managing nematode populations in the production of tomato transplants (Lycopersicon esculentum Mill.). Glean fallow was the most effective treatment in suppressing nematode numbers. After 2 years in tomato, root-knot nematodes increased in numbers to damaging ...
چکیده مورچهها با حمایت از شپشکها در مقابل دشمنان طبیعی، میتوانند برنامههای کنترل بیولوژیک آنها را مختل نمایند. طی سالهای 1389 و 1390 با نمونهبرداری از باغات مرکبات شهرستانهای ساری و بهشهر، فون و فراوانی نسبی مورچههایِ همراه با شپشکها مورد مطالعه قرار گرفت. همچنین، تاثیر تراکمهای مختلف کاست کارگر گونهی santschi lasius turcicus بر میزان تغذیه و فراسنجههای واکنش تابعی حشرات ماده و لا...
Beneficial effect of titanium on plant growth, photosynthesis and nutrient trait of tomato cv. Foria
ABSTRACT- Titanium is a beneficial element for plant since its promotive effect on plant metabolism has been well documented. However, the physiological role of this trace element in tomato is not clear. This experiment was conducted as a complete randomized design to study two concentrations of titanium (1 and 2 mg/L Ti) and 0 as control on physiological and nutrient properties of tomato cv. F...
