Drought stress is one of the most important environmental stresses that have limited the production of wheat, especially in arid and semi-arid regions of the world. To recognize drought tolerant rain-fed wheat genotypes and to determine the best tolerance/susceptibility indices, a study was conducted at the Agricultural Research Station of Miandoab for two cropping years (2013-15). The experime...

Salinity causes the adverse effects in all physiological processes of plants. The present study aimed to investigate the potential of salt stress to enhance the accumulation of the anticancer phytochemicals in Andrographis paniculata accessions. For this purpose, 70-day-old plants were grown in different salinity levels (0.18, 4, 8, 12, and 16 dSm(-1)) on sand medium. After inducing a period of...

This study was conducted to determine the effects of seed priming with ascorbic acid (AsA) on germination and seedling characteristics rapeseed (Brassica napus L.) under different salinity levels. To this end, examined five levels (0.20, 5.0, 10.0, 15.0, 20.0 dS m-1 NaCl) four doses (control, 0.5, 1.0, 2.0 mM acid). Salt stress negatively affected some plant growth traits, such as radicle lengt...

Excess of reduced iron (Fe 2+ ) will affect the plant growth rice when it is grown under waterlogged condition. Some genotypes have been identified tolerance to toxicity with different mechanism-type tolerance. This study aims identify response some toxicity, and evaluate their consistency in greenhouse screening method field The experiments were conducted hotspot area, Banyuasin (South Sumater...

Amaranth (Amaranthus tricolor), an underutilized climate smart crop, is highly nutritious and possesses diverse drought tolerance traits, making it ideal crop to thrive in a rapidly changing climate. Despite considerable studies on the growth physiology of plants subjected stress, precise trait phenotyping strategy for vegetable amaranth still not well documented. In this study, two screening t...

to study the tolerance of genotypes under terminal drought stress, 20 promising winter and facultative bread wheat genotypes were evaluated at karadj, ardebil, arak and hamedan agricultural research stations during 2001-02 cropping season. the experimental design in all the locations was randomized complete block of three replications. grain yield (yld), harvest index (hi), grain number per spi...

cold stress is one of the most important environmental stresses for rice especially in temperate and high elevation areas. in present study, the effect of different temperatures, as the main plot, including 25 (control), 10 and 5°c on 12 rice cultivars (including champa yasouj, gerde, lenjan askari, kaamfirouz, kohsar, shafagh, domsiya mamassani, dular, gharib, hasan saraei, mosa tarom and 304)...

Guar (Cyamopsis tetragonoloba (L.) Taub.) is a legume crop, and gum derived from its seeds has various industrial applications. Due to tolerance abiotic stresses, guar can be grown under water-deficit or high-salinity conditions. In this investigation, four diverse genotypes that performed at similar level in field conditions were evaluated salinity experiment the greenhouse lysimeter system. B...
