Effect of 28-homobrassinolide on photosynthesis, fluorescence and antioxidant system in the presence or absence of salinity and temperature in Vigna radiata

Physiological and biochemical traits as tools to screen sensitive and resistant varieties of tomatoes exposed to salt stress

“…A similar inferiority in the quantum yield of PS II was observed by Shahbaz et al (2008) in Triticum aestivum and by Hayat et al (2010) in Vigna radiata exposed to salinity.…”

Effect of Exogenous 24-Epibrassinolide on Salt Resistance of watermelon (Citrullus lanatus L.) under Salinity Stress

“…Therefore, the promotion of growth in watermelon plants by EBL under NaCl-stress appears at least correlatively linked with enhanced photosynthesis. Increased growth and CO2 assimilation following the application of BRs under salt stress have been reported in case the mustard [13,14] , and mung bean plant [6] . EBL activated the rate of photosynthesis may be by increasing stomatal conductance (Table 3), facilitating the diffusion of carbon dioxide into the stomatal cavity [33] .…”

“…However, the increase in RGR was attributed to the increase in the physiological growth parameter (NAR) rather than the morphological growth parameter (LAR).Thus suggests that EBL-induced salt tolerance in watermelon plant. Since salinity inhibits plant growth by adversely affecting various physiological and biochemical processes including photosynthesis, antioxidant capacity, and ion homeostasis, it is suggested that BRs enhanced growth of salt stressed plants might have been due to BRs-induced changes in these physiological or biochemical processes [6,13,14,15] . For example, Ali [14] reported that EBL increased growth in Indian mustard plants could be related to enhanced activity of antioxidative enzymes and proline level that protect the plants from oxidative damage.…”

“…In addition to stimulating growth, BRs have an anti-stress effect on plants. Previous studies showed that salt tolerance of rice [13] , chickpea [14] , Indian mustard [15] and mung bean [6] could be markedly enhanced by the application of brassinosteroids.…”

“…5th International Conference on Advanced Design and Manufacturing Engineering (ICADME 2015) Various agronomic and physiological practices are applied to minimize the adverse effects of salinity on the normal functioning of plants.Moreover, plant growth regulators, both natural and synthetic, are widely applied to agricultural crops as a means of crop improvement [6] . Brassinosteroids (BRs) represent a group of naturally occurring steroidal lactones widely distributed in plant kingdom.…”
