Effects of salinity and drought on growth, contents of proline, malondialdehyde (MDA), proteinand activity of antioxidative enzymes were studied in two Trigonella species. Seeds andexplants of T. foenum-graecum and T. aphanoneura were grown on Murashige and Skoogmedium (MS) complemented with iso-osmotic concentrations of NaCl (0, 100, 150 mM) andmannitol (0, 180, 275 mM). Growth and relative wa...

Root exudates have important, yet incompletely known, roles in plant physiology, mainly in rhizosphere interactions with other organisms. Proline might play a critical role in protecting plants under stress, particularly under saline conditions. However, as far as we know, no attempts have been made to determine the proline content of root exudates. Here, we present preliminary results of the q...

background: some health-protecting secondary metabolites can be found at a higher concentration in the sprouts compared to other stages of plant growth. in addition, environmental stresses such as salt stress may be resulting in the increase or decrease of specific secondary metabolites in sprouts and plants. objective: evaluation the changes of trigonelline, nicotinic acid, and proline content...

this study was carried out to evaluate the changes in some important cell parameters under water limitation in sorghum genotypes. a factorial experiment was conducted based on randomized completely design in greenhouse, in university of mohaghegh ardabili in 2014. treatments were water stress at levels of 85, 65, 45 and 25 percent field capacity in and three genotypes of forage sorghum (kfs2, k...

this study was conducted to evaluate changes in antioxidants, free proline, relative water content and determination of root colonization of four commercial wheat (triticum aestivum l.) cultivars (azar2, darab2, shiraz, and falat) inoculated with the fungus glomus intraradices, under four water regimes of 100, 75, 50, and 25% of field capacity in the year 2010 at the school of agriculture, shir...

to study the effect of humic acid and drought stress on some physiological characteristics of roselle (hibiscus sabdariffa) an experiment was conducted in the research field of agricultural education centre of jiroft in 2013. field experiment was carried out as split plot design with three replications. water deficit stress as main factor with three levels (a1 = irrigation after 50, a2 = 100 an...

Hydroponic experiments were performed to exam the dynamic change of endogenous proline in rice seedlings exposed to potassium chromate chromium (VI) or chromium nitrate chromium (III). Although accumulation of both chromium species in rice seedlings was obvious, more chromium was detected in plant tissues of rice seedlings exposed to chromium (III) than those in chromium (VI), majority being in...

Drought stress is one of the leading constraints to wheat (Triticum aestivum L.) production globally. Breeding for drought tolerance using novel genetic resources is an important mitigation strategy. This study aimed to determine the level of drought tolerance among diverse bread wheat genotypes using agronomic traits and proline analyses and to establish correlation of proline content and agro...

The 45-days-old seedlings of drought resistant (N-22, CR143-2-2) and susceptible rice (Oryza sativa L.) genotypes (Panidhan, Pusa-169) were subjected to osmotic stress in PEG-6000 solution of -10 and -16 bar and the relative water content (RWC), proline content, and pyrroline-5-carboxylate synthetase (P5CS) activity and its P5CS expression were studied. A gradual decrease in RWC was observed in...
