Terminal buds of dark-grown pea (Pisum sativum) seedlings have an indole-3-acetic acid oxidase which does not require Mn(2+) and 2,4-dichlorophenol as cofactors. Oxidase activity is at least 50 times higher in buds of tall peas than in dwarf seedlings. Administration of gibberellic acid to dwarf peas stimulates both growth and indoleacetic acid oxidase activity to the same levels as in tall see...

In order to investigate physiological and biochemical changes of wheat under stress residue of Imazethapyr herbicide (Imazethapyr), an experiment was conducted in a completely randomized design with four replications in greenhouse conditions at university of Mohaghegh Ardebili. The treatments consisted of five dose levels of herbicide Imazethapyr (0, 0.011, 0.022, 0.033 and 0.044 micrograms of ...

In order to investigate the effects of water stress on total phenolics content, antioxidant power, β-glucosidase activity and stomatal properties of alfalfa, a factorial experiment based on randomized complete block design was carried out in 1-Lit pots containing half strength Hoagland culture medium using two cultivars of alfalfa at four osmotic pressures including 0 (control), -0.5, -1.0 and ...

in this study, biocontrol effect of some strains pseudomonas fluorescent surveyagainst pythium aphanidermatum the causal agent of cucumber root rot disease. first biocontrol ability of bacteria against the fungal pathogen evaluated by cross-culture method. results showed that inhibition zone of strain t17-4 (7.5 mm) was more than others. seven strains including t17-4, cha0, cha89, vupf52, vupf5...

to study the effect of salinity on physiological and morphological traits of chickpea in 2010 at faculty of agriculture and natural resources, university of tehran with seven chickpea genotypes. two experiments design was rcbd with 3 replications and 5 levels of salinity stress (ctrl, 200, 150, 100, 50 mm) for laboratory experiment on germination indices and greenhouse experiment on physiologic...

the chemical compound dl-?-amino-n-butyric acid (baba) has been introduced as a promoter of induction of resistance in plants against plant pathogens. in this study, promotion of induction of some such defense compounds as peroxidase and polyphenol oxidase enzymes through dl-?-amino-n-butyric acid application against root knot nematode (meloidogyne javanica) was investigated in cucumber. result...

root-knot nematodes (meloidogyne spp.) are among the most important groups of plant-parasitic nematodes, causing damage and yield losses to most cultivated plants. the bacterium pseudomonas fluorescens cha0 and the fungus trichoderma harzianum bi were investigated for biological control capability and systemic induction of resistance against the nematode m. javanica under glasshouse conditions....

Abstract Root-knot nematodes ( Meloidogyne spp.) have been reported to be responsible for large economic losses of agricultural crops due their wide host range and variety suitable climates. The control measures these parasitic depend upon synthetic nematicides a small number bio-based products. Chemical are eliciting adverse effects on the environment human health. In present study, an alterna...
