Stomatal resistances and turgor pressures were measured during a 12-day period on leaves of bean (Phaseolus vulgaris L. cv. Contender) which were treated with kinetin, were salinized or were treated with kinetin and salinized. Stomatal resistances were highest in salt-stressed plants, and progressively lower in salt-stressed and kinetin-treated plants, control plants, and kinetin-treated plants...

Naive mated female cabbage looper moths, Trichoplusia ni Hübner, responded in a flight tunnel to potted potato plants ( Solanum tuberosum ). Percentages of moths attracted to uninjured potato plants, mechanically-damaged potato plants, and potato plants treated with regurgitant from larvae of the Colorado potato beetle, Leptinotarsa decemlineata Say, were similar, indicating no effect of plant ...

Oxidative stress is a major threat for plants exposed to various environmental stresses. Previous studies found that transgenic potato plants expressing both copper zinc superoxide dismutase (CuZnSOD) and ascorbate peroxidase (APX) (referred to as SSA plants), or nucleoside diphosphate kinase 2 (NDPK2) (SN plants), showed enhanced tolerance to methyl viologen (MV)-induced oxidative stress and h...

Determination of the most important problems on medicinal plants in Iran in relation to Education, Management, Research and Development and Domestication of endemic and exotic medicinal plants. This study was a measuremental study in 2002 based on 36 filled questionnaire distributed among researchers and professionals in Iran. - 89 percent of researchers and professionals believed in a lack of ...

In order to evaluate cardinal temperatures and optimum thermal range of germination of three medicinal plants including Thymus transcaspicus, Foeniculum vulgare and  Calligonumjunceum  an experiment was conducted in a Completely Randomized Design with three replications. Therefore, this experiment was conducted to study of the seed germination characteristi...

A full-length cDNA copy of the genome of Potato leafroll virus (PLRV) was introduced into the genome of tobacco and potato plants by Agrobacterium tumefaciens-mediated transformation. Transgenic lines were obtained in which the transgene was readily detected by PCR with DNA extracted from T(1) tobacco seedlings and clonally multiplied potato plants. PLRV-specific genomic and sub- genomic RNAs, ...

Photoacclimatory responses of the seagrass Zostera marina in the intertidal and subtidal zones were investigated by measuring chlorophyll a fluorescence parameters, photosynthetic pigments, leaf δ13C values, and shoot morphology in two bay systems. Intertidal plants had higher carotenoid concentrations than subtidal plants to avoid photodamage under excess light conditions during the day. The m...
