...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...

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...

... (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...

...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...

Comparison of Soil and Hydroponic Based Screening Process to Select Salt Tolerant Wheat Varieties

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...
