...ckel resistance under Ni salt stress. This study was centered on assessing the adherence, motility, hydrophobicity, aggregation and biofilm formation of two salt tolerant strains [Bacillus subtilis and Halomonas aquamarina (1)] in the presence of nickel. Two concentrations of nickel were used i.e., 500μg/ml and 1000μg/ml for subsequent tests. The results revealed that at low/ sub-inhibitory concentration of nickel (500 μg/ml), motility is inhibited; a...

...y with PGPR strain under salt stress. The root length, plant height, root and shoot weight increased up to 40%, 40%, 167% and 255%, -1 respectively over un-inoculated at 12 dS m salinity level. Whereas an increase of 38%, 54%, 109%, and 117% in root length, plant height, root weight and shoot -1 weight, respectively was observed over un-inoculated at 10 dS m salinity level. Improvement of 25%, 47%, 112%, and 98% in root length, plant height, root weight, -1 sh...

RESPONSE OF DIFFERENT COTTON ( L.) GENOTYPES AT VARIOUS SALINITY LEVELS
...nbsp;Keeping in view the salt stress threat in Pakistan, a hypothesis was developed that up to what level of salt, the cotton genotypes can survive so that it may provide the shelter for income from textile industry, as mainly the textile industry depends upon cotton production. High salinity levels hamper the boll formation in cotton genotypes as it reduces the yield. To verify this fact, study was carried out under natural conditions as pots experiment in so...

...th and development under salt stress. Keeping in view these factors a hydroponic experiment was conducted on wheat with two levels of salicylic acid (0.25 mM and 0.50 mM) under two salt levels (75 mM and 150 mM) to assess that whether the salicylic acid is helpful in coping the harmful effects of salinity on crop growth or not and if it has certain positive response then which level is more suitable for wheat crop growth along with the genotypic assessment of ...

... (0.25 and 0.5 mM) under salt stress (75 and 150 mM). It’s an obvious factor that under salt stress certain reactive oxygen species are produced that damage the vital plant organelles causing disturbances in the normal functioning of the plant and even may lead to death in severe cases. The results of this study conferred that there were genotypic variation found in two genotypes regarding salinity tolerance. SARC-4 wa...

From obtained results it is concluded that, increase level of RWC, proline, sugar and chlorophyll in transgenic plants contributed in enhance drought and salt tolerance.

...d becomes at threat. The salt stress is translated into decrease in growth rate and resultantly, biomass production decreases significantly. This reduction is gradual, depending upon increase in salt concentration in the root medium, while each species has a critical threshold value where it was started showing negative response. Leaching fractions may help keeping salt concentration low in the root zone when irrigation water is saline. In this experiment thre...

...d in all varieties under salt stress. Varieties i.e. V07096 and V05082 showed higher rate of photosynthesis and potassium contents than V05003 and V07194. The salt-tolerant and salt-sensitive genotypes, V07096 and V05003, respectively were then grown in soil medium. Lower plant sodium contents in soil medium were also observed in V07096 variety under salt stress treatments than V05003. Salt tolerant variety also showed highe...

The minimum relative growth rate was recorded as 68% to respective control in S-907 genotype at 100 mM NaCl while it was 38% of respective control in C-99-3-115 genotype at 200 mM NaCl stress conditions. In linseed growth, K+/Na+ratio proved to be a critical factor in relative growth rate and biomass production while the ability of linseed genotypes to accumulate Na+ at root level and to restrict the entry of th...

Three concentrations of trehalose (0, 5 and 50 mM) were applied to plant foliage, subjected to varying levels (0, 11 and 17 dSm-1) of salinity. Salt stress disturbed the sodium and potassium concentrations in leaves and roots of plants. Different morphological traits of plants including number of leaves, leaf fresh weight, shoot fresh weight, root fresh weight, plant he...

Its 50 % yield reduction occurs at ECe 5.9 dSm-1 and ESP value of 25-30. A field experiment was conducted on saline sodic soils to determine fertilizer requirement of linseed. The selected field was saline sodic in nature with pH value 8.57, medium in extractable K and scarce in P and organic matter. The selected field was ...
