background & aim: effects of ultra violet spectrum on plants due to their obligatory requirement for sunlight for survival are unavoidable. direct effects of uv on plant growth and development are generally negative and usually they use many different defense mechanisms to acclimate and protect themselves. material & methods: the present research for the first time was conducted to inv...
In vitro regeneration of two cultivars of carnation, namely, ‘Nelson’ and ‘Impulse’ was studied through direct somatic embryogenesis. Somatic embryos were formed directly on petal explants cultured on Murashige and Skoog (MS) medium containing different concentrations (0.2, 0.5, 1, 2, 4, 6 mg 1-1) of picloram. Maximum embryogenesis was obtained with 1 and 2 mg/l picloram. Globular shaped embryo...

this study examined the effects of collaborative strategic reading and direct instruction in persuasion on iranian high school students persuasive writing and attitudes. students in three intact classes were assigned to one of three treatment conditions: collaborative strategic reading and direct instruction in persuasion or direct instruction in persuasion or a control group. treatment effects...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
To develop an alternative method for production of sarsasapogenin by plant tissue culture technique and its quantification in Asparagus racemosus and its in vitro cultures using HPTLC. Murashige and Skoog’s (MS) basal medium supplemented with various growth regulators was used for development of shoot and root calli while, hormone free MS medium was used for development of Agrobacterium tumefac...
Pluronic F127 polyol, a block copolymer of propylene oxide and ethylene oxide, was studied as an alternative to agar in culture media for nematodes, bacteria, fungi, actinomycetes, and plant tissues or seedlings, At a polyol concentration of 20% w/v, the culture media, semi-solid at room temperature (22 C) but liquid at lower temperatures, had minimal effects on the test organisms. Most of the ...
findings in relation to the inhibitory effects of natural substances against microorganisms showed that herbal products may be alternatives to synthetic and chemical drugs due to their significant therapeutic effects. the pennyroyal ( mentha pulegium ) as an important medicinal plant, belongs to the lamiaceae family is applied in the pharmaceutical and food industries. in recent years, plant ti...
