thyme (thymus vulgaris l.) is an aromatic and medicinal plant which is very important for the herbal industry. in this research, in vitro selection for nacl tolerance was investigated in this plant. hypocotyl and shoot explants (apical meristem and cotyledonary leaves) of sterilized seedlings were cultured in ms medium supplemented with different combinations of 2, 4-dichlorophenoxyacetic acid ...

Peppermint (Mentha piperita L.) is one of the most important plants producing essential oil. An experiment was carried out using a randomized complete block design with 3 replications to study the effect of salinity stress on growth parameters, essential oil percent of peppermint. 4 levels of salinity solution containing 0, 50, 100 and 200 mmol NaCl was applied in irrigation plantings ...

Strawberry is considered as a salinity sensitive species and is adversely affected in response to the salt stress in terms of growth and yield. Pot experiments were conducted to determine the effect of exogenous salicylic acid (SA) application on physiology, growth, chlorophyll and mineral content of strawberry grown under salt stress and greenhouse conditions. Strawberry plants were treated wi...

Present study deals with the isolation and characterization of desiccation tolerant bacteria Micrococcus luteus-chp37 from rhizosphere of plant growing in the Cholistan desert of Pakistan. To check the desiccation tolerance, strain was incubated at various levels of relative humidity (5, 27 and 100%) for a period of 6, 12 and 18 days. The surviving fractions of M. luteus-chp37 after 18 days of ...

Peppermint (Mentha piperita L.) is one of the most important plants producing essential oil.

In order to study the effect of silver nanoparticles and magnetic field on Raphanus sativus. experiments were carried out with four treatments in 10 days. Treatments were including (CON) control, (MF) magnetic field with B=1.8 mT for 1h per day in 10 days, (SNPs) silver nanoparticles (50 ppm), (MF+SNPs) magnetic field plus silver nanoparticles. Results showed that silver nanoparticles (SNPs) ha...

Penicillium spp. produce a variety of beneficial metabolites for plant growth and survival, as well as defend their hosts from attack of certain pathogens. In present study 20 Penicillium spp. culture filtrates were screened for growth activity in wheat seedlings. Germination percentage of wheat seeds was enhanced by Penicillium spp. culture extracts. Although, the most active inhibitors of see...

In this study, the role of salicylic acid pre-treatment (0.01, 0.1 mM was investigated)in inducing salt tolerance in sweet basil. Results showed germination percentage, length of shoot and root, fresh and dry weight of leaf, and photosynthetic pigments were decreased in response to high salinity but the lipid peroxidation, coefficient allometry, and soluble sugars increased. In plants pre-treat...
