The objective of this study was to investigate the effect of exogenous application of salicylic acid concentrations on the physiological and biochemical traits and essential oil content of chamomile under normal and heat stress conditions as induced by delayed sowing. The experiments were conducted during 2011–2012 as a factorial using a randomized complete block design with three replications,...
The salinity of the soil and irrigation water is one great challenges agriculture. Salinity can have harmful effects on physiological processes plant growth, including Tropaeolum majus L. (Tropaeolaceae). application phytohormones be a strategy to mitigate these effects. aim this study was evaluate jasmonic acid, salicylic cytokinin polyamine as attenuators salt stress in T. majus. Three levels...
salicylic acid play an important role in plants physiological processes. in this research the effect of salicylic acid on induction of somatic embryogenesis and plant pigments synthesis in the phloem and petiole explants of carrot in the b5 medium was investigated. we added treatments with 0, 0.5, 1.5, 2 and 3 mm to culture medium by experimental base on the randomized design to investigate the...
S. rebaudiana produces steviol glycosides including stevioside and rebaudioside A that are valuable as low calorie sweeteners. The objective of this study was to investigate the effects of salicylic acid elicitation and sampling times on the improvment of stevioside and rebaudioside A production and KA13H, UGT74G1 and UGT76G1 genes expression. The results showed that the addition of different c...
Salinity is one of the factors limiting the growth and development of the plants that has a negative effect on morphological and physiological processes in plants and in order to reduce these adverse effects used to from growth regulators. In this study, the effect of hormone Salicylic acid (SA) at 3 levels (0, 1 and 2 mM) to relieve stress (NaCl Soluble at concentrations of 0, 50, 100 and 200 ...
Phytohormones are not only instrumental in regulating developmental processes in plants but also play important roles for the plant's responses to biotic and abiotic stresses. In particular, abscisic acid, ethylene, jasmonic acid, and salicylic acid have been shown to possess crucial functions in mediating or orchestrating stress responses in plants. Here, we review the role of salicylic acid a...
Lily (Lilium longiflorum L.) is one of the most important potted flowers, which is used largely as cut flower. An experiment, arranged as a factorial besed on completely randomized dasign with three replications, was carried out to evaluate the effects of pre-harvest foliar application of humic acid, salicylic acid and calcium chloride on quality and longevity of lilium cut flowers. Treatments ...
Salicylic acid (SA) is an endogenous plant growth regulator, acting as non enzymatic antioxidant and has a regulatory effect on some physiological and biochemical processes. Therefore, this work was conducted during two successive summer seasons to evaluate the performance of two sunflower cultivars (Sakha 53 and Giza 102) to salicylic acid. The plants were grown at the experimental station of ...
This experiment conducted on rosemary plant (Rosmarinus officinalis L.), aimed to investigate the effect of gibberellic acid (GA3), salicylic (SA), and NPK fertilizer growth chemical constituents as well determining best concentration. After two weeks from planting rooted cuttings in plastic pots were sprayed with SA at three concentrations (0, 150 300 mg l-1), GA3 Sprayed 400 Nano (3 6 g contr...
