We examined the distribution and the immunohistochemical localization of yieldin in etiolated cowpea seedlings with an anti-yieldin antibody. An immunoblotting analysis revealed that the yieldin was located in the aerial organs (plumule, epicotyl and hypocotyl) but not in the roots. The intensity of the yieldin signal in the hypocotyls was highest in the apical pre-elongation region (the hook r...

This research was conducted to assessment effect of different concentrations of sodium hypochlorite along several times on quantitative parameters of wheat seeds affected by Aspergillus flavus fungus via factorial experiment according randomized complete block design with four replications. The treatments consisted four concentrations of sodium hypochlorite or NaClO (C1= 2%, C2= 4%, C3= 6%, and...

Abstract An insect-pathogen fungus called Beauveria bassiana (Balsamo) Vuill. is employed as a biological control for variety of insect pests. B. not only acts an entomopathogen, directly infecting and killing pests, but it also has the ability to live endophyte on plants, colonize plant tissues, consequently boost growth. This research was undertaken find out whether can cabbage what impact se...

soil and water salinity in arid and semi-arid regions, is one of the most important stresses, can severely limit crop production. black cumin (nigella sativa l.) is annual important herbal plant in rununculaceae family that sense to salinity. this study was conducted to evaluate the effects of the priming on seed germination of black cumin under saline stress. the experiment was carried out as ...

Drought is one of the most important natural phenomenon which affects on plant growth. Alfalfa (Medicago sativa L.) is an essential fodder product which has extensive and depth roots system, this advantage enables the plant to tolerate long term drought without any damage to its regrowth process. In order to measure germination percentage and rate, root and shoot growth of 6 alfalfa cultivars (...

Exposure of seedlings of winter rye (Secale cereale L., cv. Puma) for 2 weeks or 24 hours to desiccation stress (40% relative humidity) at room temperature (21 degrees C) in the dark induced degrees of freezing and drought tolerance in the plumules comparable to those produced by cold conditioning for 2 weeks at 3 degrees C. The induction was associated with repression of growth and could not b...

In order to evaluate the effects of priming materials and duration of priming on the seed physiological enhancement and biochemical traits of germination in pumpkin seeds a factorial experiment was conducted based on a completely randomized design with three replications at the University of Mohaghegh Ardabili. Treatments were priming with water, NaCl (3%), gibberellic acid (20 mg L-1), and asc...
