Moniliophthora perniciosa infects young meristematic tissue of Theobroma cacao and induces abnormal shoot development and ultimately necrosis. We analyzed culture filtrates of M. perniciosa to identify metabolites with possible effects on witches’ broom disease symptom development. All isolates produced salicylic acid (SA), phenyllactic acid and mandelic acid. When SA levels were measured in pl...

The combined effect of salicylic acid (SA) (100, 200 and 400 ppm) and water stress (waterlogging and drought) on growth, reactive oxygen species generation and activities of enzymatic and non-enzymatic antioxidants were studied in soybean (Glycine max L. Merr.) leaves.The results proved that the interaction of salicylic acid with water stress significantly increased total protein content and de...

Plant defense in response to microbial attack is regulated through a complex network of signaling pathways that involve three signaling molecules: salicylic acid (SA), jasmonic acid (JA) and ethylene. The SA and JA signaling pathways are mutually antagonistic. This regulatory cross talk may have evolved to allow plants to fine-tune the induction of their defenses in response to different plant ...

In order to study effect of salicylic acid and calcium foliar application on growth, yield and yield components of strawberry plants as a factorial in completely randomized experimental design with four replications. This factors included of salicylic acid in 3 levels (0.25, 0.5 and 0.75 mM) and calcium in 2 levels (2.5 and 5 mM) spray on strawberry. Results showed that salicylic acid (0.25 mM)...

Effect of salicylic acid combined with glutamin on rose (Rosa Baccara) cut flowers was studied. The study was conducted in a factorial arrangement, carried out in a complete randomized design. The factors were Salicylic acid (0,1, 2 and 4 mM) and glutamin (0, 1.5 and 3 mM).The effects of treatments on the total chlorophyll content, ACC-Oxidase activity, anthocyanin leakage, membrane stability a...

to study the effects of drought stress and foliar application with salicylic acid on yield andit’s components and percentage of essential oil of nigella sativa l., a field experiment was conducted as split plot based on randomized complete block design with three replications at research farm of shahid bahonar university of kerman during growing season of 2013- 2014. the main factor was drought...

introduction salinity has various effects on plant growth by affecting physiological processes. the decline in plant productivity under saline condition, frequently linked with the reduction of photosynthetic capability. it has been reported that efficiency of psii photochemistry (fv/fm) of numerous plant species have been decreased due to salt stress studies have shown that salicylic acid (sa...

salicylic acid (sa) is part of a signaling pathway that is induced by a number of biotic and abiotic stresses. it has been recognized as an endogenous regulatory signal in plants. in order to study the effect of different concentrations of sa on germination, growth and some physiological parameters in chickpea (cicer arietinum l.) two genotypes (mcc414, mcc361) under drought stress conditions, ...

Sainpaulias are among the most popular flowering plants and there are so many variations in flower shape, size and color. Aqueous solutions of 0 M to 10 M concentrations of salicylic acid (SA) were foliar-applied on two African violet cultivars to evaluate the influence of different rates of SA on growth and flowering of plants. The solutions were applied to leaves of plants 14, 21, 28 and 35 d...
