THE EFFECT OF SALINITY STRESS ON PROLINE METABOLISM IN TWO WHEAT (TRITICUM AESTIVUM) CULTIVARS
Authors
Abstract:
The effect of various NaCl treatments (0, 50, 100, 200 and 300 mM) at different growth and development stages (tillering, boot swelling, flowering and polination) of two wheat cultivars (Ghods : salt-sensitive; Boolani : salt-resistant) on proline concentration and the kinetic activity of proline dehydrogenase was studied under greenhouse conditions. Generally, in response to salinity treatments, the increase of proline level and the decrease of proline dehydrogenase activity in Ghods leaves were greater than in Boolani leaves. It is therefore concluded that, proline metabolism is probably one of the biochemical mechanisms influencing the response of these cultivars to salt stress.

THE RESPONSE OF FOLIAR PROTEINS IN TWO WHEAT (TRITICUM AESTIVUM) CULTIVARS TO SALT STRESS
Effect of various NaCl treatments (0, 50, 100, 200, and 300 mM) at different growth and development stages (tillering, boot swellen, flowering and anthesis) in two wheat cultivars (Ghods: salt – sensitive, Boolani: salt – resistant) on SDS-PAGE electrophoretic pattern of leaf proteins was studied under greenhouse conditions. Generally, in response to salinity treatments, the decrease in protein...

The effects of salinity stress on grain quality traits of wheat were investigated using 180 lines of F5 generation in two environments (normal and salinity stress). A randomized complete block designs with three replications was used in each of the environments at the Research Farm of the Agricultural and Natural Resources Research Station of Isfahan in 2019-2020 cropping season. Grain yield, p...
full textEffect of salinity stress and application of salisylic acid on expression of TaSC and TaNIP genes in two bread wheat (Triticum aestivum L.) cultivars
Salinity is one of the environmental stresses that affects bread wheat grain yield in most parts of the world. One of the basic strategies to mitgiate the effect of non-biological stresses such as salinity is genetic improvement of crop plants. Identification of stress-associated genes is a prerequisite for genetic improvement. In the present study, the role of a number of genes in the aquapori...
full textPotassium induced salinity tolerance in wheat (Triticum aestivum L.)
Water culture experiments were conducted to study the response of ten wheat genotypes to external K application (10 mmol KCI dm3) at seedling stage under saline condition (0 and 100 mmol NaCl dm3). The data showed that there was an increase in the shoot and root length with the application of external K. The increase was more pronounced under control than under saline conditions. The better per...
full textVernalisation Response of Some Winter Wheat Cultivars (Triticum aestivum L.)
For 17 cultivars of winter wheat (Triticum aestivum L.) different vernalisation and photoperiod responses were detected. The effect of photoperiod sensitivity was not significantly changed by vernalisation; different vernalisation responses were probably due to the presence of multiple alleles at Vrn loci. The delay in heading depended on the vernalisation deficit exponentially: y = parameter (...

The present experiment was conducted to assess the interactive effect of foliar application of nitric oxide (NO) and salinity on wheat (Triticum aestivum L.). Wheat cv. S-24 was grown under non-stressed or salt stressed conditions (0 and 150 mM NaCl). Different levels of NO (water spray, 0.05, 0.10 and 0.15 mM) were applied as a foliar spray. Salinity applied through rooting medium significantl...
