Effect of methyl salicylate (MeSA), an elicitor on growth, physiology and pathology of resistant and susceptible rice varieties

Abstract

Methyl salicylate (MeSA) is a volatile organic compound synthesized from salicylic acid (SA) a plant hormone that helps to fight against plant disease. Seed treatment with MeSA, is an encouraging method to the seed industry to produce more growth and yield. The aim of our study is to find out the growth, development and disease tolerance of rice seed treated with different concentrations of MeSA. Also the seed treatments were studied to determine whether they directly influenced seedling emergence and growth in rice (Oryza sativa L) cultivars ‘IR 20, IR 50, IR 64, ASD 16, ASD 19 and ADT 46’ under greenhouse condition. MeSA seed treatments at 25, 50, 75 and 100 mg/L significantly increased seedling emergence. Effects were stronger in IR 50, and IR 64 and the effects were dose dependent, although the relationship between dose and effect was not always linear. MeSA seed treated rice plant against bacterial blight were analyzed. Bacterial blight was more effectively controlled by the seed treated with 100 mg/L than others. These results suggest that seed treatment with MeSA alters plant physiology in ways that may be useful for crop production as well as protection.

“…Seaweeds are being sought out as potential enhancers of crop growth and yield and are replacing chemical fertilizers owing to higher efficiencies, broader action range, eco-friendly nature, and cost-effective feature. Seaweeds, reported with outstanding plant growth promoting potentials, increased plant height, root as well as shoot lengths, consequently, are designated as plant growth biostimulants, as reviewed by Khan et al [7] and Craigie [33] As a crucial and initial plant growth activity, the evaluation of a seed's germination and associated parameters can help in determining the rate of a crop success, in terms of yield and economy [34]. As contemplation, the current investigation was performed to determine the plant growth stimulant activities of green seaweed U. flexuosa (Chlorophyceae).…”

Effects of exogenous methyl jasmonate and salicylic acid on rice resistance toOebalus pugnax

“…Recently, it has been reported that methyl salicylate is an efficient elicitor for rice both in plant treatment, inducing defense against the leaf folder, Cnaphalocrocis medinalis Guenée, 1854 (Lepidoptera: Crambidae), and in seed treatment, to protect against bacterial blight disease ( Xanhomonas oryzae pv. oryzae ( Xoo ) …”

Effect of methyl jasmonate (MeJA)‐induced defenses in rice against the rice leaffolderCnaphalocrocis medinalis(Guenèe) (Lepidoptera: Pyralidae)

“…However, chemical insecticide application against the rice leaf‐folder is not advisable because of pest resistance and resurgence. Furthermore, rice leaf‐folders have a vast array of natural enemies that help maintain their populations below economic loss levels . The rice leaf‐folder has grown in economic importance with the introduction of high‐yielding rice strains and constant cultivation of the crop…”
