Salinity is one of the most important constrain affecting crop growth and productivity. Hence studying salinity at morphological and biochemical point of view has become the basis for understanding salinity and plant interactions. Under stress, plants survive by enhancing the osmolyte accumulation by complex metabolic activities. Present investigation deals with the effect of salinity on growth...

Salinity is a major limiting factor for plant growth and development. To evaluate the impact of P5CS gene expression under in vitro salt stress condition, transgenic tobacco (Nicotiana plumbaginifolia) carrying P5CS gene and non-transgenic plants were treated with 0, 100, 150, 200 or 250 mM NaCl for 28 days. Proline content, lipid peroxidation and the activity of some antioxidant enzymes after ...

Analysis of DNA samples for restriction fragment length polymorphisms requires correct recognition of the normal restriction sites. Some restriction endonucleases have been shown to exhibit altered cut site specificity (star activity) under certain reaction conditions (1, 2). We report here the results of experiments demonstrating Hinfi star activity. Two ngs of pUC18 DNA or SV40 DNA were diges...

The present study was carried out to show the negative impact of different concentrations sodium chloride (100, 150, 200, 250 and 300 mM) on germination rate 7-day old maize seeds, according results by measuring growth criteria germinated seeds both mM Nacl these concs nearly lethal seed so, ignored in next experiments complete step with three only 150 200 Nacl. Also, our accomplished improve 1...

Salinity and heavy metal stresses are a great hindrance to the germination development of plants. Nickel (Ni) is an indispensable micronutrient for plants at low concentrations. However, proficiency depends upon plant types. Citrullus colocynth medicinal cucurbit weed. The contemporary target study appraise influence combined by varying concentrations sodium chloride nickel on germination, morp...

theeffect of salt stress on the pysiological and biochemical responses of the seedlings of eight eucalyptus species viz. e. kingsmillii, e. tetragona, e. salubris, e. occidentali, e. microtheca, e. camaldulensis, e. globules and e. sargentii was analyzed. four month-old seedlings grown in greenhouse were watered by five levels of salt solution (0, 50, 100, 150 and 200 mm of nacl) in five replic...

Treatment with solutions containing high concentrations of NaCl (200 or 300 mM) induced cell death in rice (Oryza sativa L.) roots, as well as the application of exogenous hydrogen peroxide (H2O2). Moreover, the pretreatment with dimethylthiourea (DMTU), a scavenger of H2O2, partially alleviated the root cell death induced by 200 mM NaCl. These observations suggest that the cell death of rice r...

Given that the characteristic of free floating plants to uptake metals can have a positive effect on the efficiency of the remediation process of a wetland, it is important to investigate the factors that may impact the process of uptake of metals by the plants. By conducting this present study over a short duration of time, the effects of salinity on the growth, the content of the photosynthet...

effects of culture medium containing hormonal compositions on phenotypic and chromosomal variations of sugarbeet cultured tissues were examined. experiments were carried out in different nacl levels. cytological studies were conducted on calli originated from suspension culture. hypocotyl of seven day old seedlings of the two diploid lines were cultured in ms medium containing hormonal composit...
