Seed priming is widely recognized as a significant phenomenon for synchronizing germination and enhancing the vigor of seeds. Seeking importance priming, influence magnetic treatments in overall performance plants cannot be undermined well. In present study, seeds Pisum sativum L. Plantago ovata Forssk. were primed with essential Plant Growth Regulators (PGRs) such as; Gibberellic acid (GA3), P...

salicylic acid (sa) plays a key role in plant disease resistance and hyper-sensitive cell death but is also implicated in hardening responses to abiotic stress. the aim of this study is to examine the effects of salicylic acid on the growth, eco-physiological and biochemical characteristics in zinnia elegans plant exposed to copper stress. effects of copper (cu) on biomass, root length and shoo...

The effect of applying plant growth regulators on seed yield and quality of guinea grass (Panicum maximum) cv. Tanzania was studied in one crop on a sandy clay in Mexico. The treatments consisted of 3 growth regulators [ethephon, salicylic acid and a steroidal phytohormone (cidef-4)], 2 stages of application (before seed head emergence and at the beginning of anthesis) and 4 application concent...

wheat is one of the most important crops in the world that is constantly faced with the different biotic and abiotic stresses. programmed cell death is one of the methods for coping with different stress which is stimulated by several factors. because salicylic acid is involved in resistance to various stresses, to explore the effects of salicylic acid on programmed cell death, the effects of s...

The effect of five antioxidants (citric acid, salicylic acid, benzoic acid, ascorbic acid, and sodium citrate) on the resistance of tomato plants (Lycopersicon esculentum Mill) to early blight disease incited by Alternaria solani was investigated in vitro and in vivo. The results indicated that all of the antioxidants tested markedly inhibited the mycelial growth of A. solani in vitro. The degr...

saffron (crocus sativus l.), the most valuable medicinal food product, belongs to the iridaceae family, which has been widely used as a coloring and flavoring agent. the stigmas contain three major compounds; crocins (carotenoid compound responsible for color), picrocrocin (responsible for taste) and safranal (responsible for odor). it has been used for medicinal purposes, as a spice and condim...

frost in early spring is one of the limiting factors in the production of grape. chemicals offer useful approach to reduce low temperature-induced damages. different concentrations of salicylic acid including: 0 (control), 0.5, 1 and 2 mm were sprayed twice on 10 year-old ‘bidaneh sefid’ grape vines at full bloom stage and changes in leaf soluble carbohydrates, proline and protein levels were m...

Soybean meal (SBM) was treated with acid or alkali to determine effects on N solubility, in vitro NH3-N accumulation, in situ N degradability, and N digestion and retention in growing lambs. The following SBM treatments resulted in decreased (P less than .05) N solubility and in vitro NH3-N accumulation compared with control SBM: spraying with 2.5 or 5% acetic or propionic acid, soaking in .5 N...

NEDKOV, N., 2007. Research on the Effect of Pre-sowing Treatment on Seed Germination of Hypericum perforatum L. Bulg. J. Agric. Sci., 13: 31-37 Trials were carried out for improvement of seed germination of St. John's Wort (Hypericum perforatum L.) based on studies of main sowing properties after treatments as follows: soaking, soaking and heating and combined seed stratification. Recommendatio...
