“…However, pesticidetreated plants showed significantly higher performance at early growth stages and become less competitive to JA2 treatment over time. Similar finding was also reported by Cipollini and Redman (1999) as the application of JA induce resistance in plant to defense herbivores attack and diseases for a long time.…”

ABSTRACT:The excessive application of pesticides for agricultural production has raised quite some concern about environmental safety and sustainability. To reduce environmental impact of pesticide overuse, there is an increasing interest in using different elicitors including Jasmonic acid (JA) to induce resistance against pathogen and insect in crop. Chilli (Capsicum annuum L.), which is an important vegeTable cum spice crop around the world. The aims of this study were to compare the effectiveness of Jasmonic acid on growth, Phyto-physiological responses, yield and viruses control in chilli plant. It was evaluated the effectiveness of single spray of JA (JA1), double spray of JA (JA2), conventional pesticide (Malathion 50%) and without any of those or control. The experimental results showed that pesticide-treated plants perform much better at early growth stages and become less competitive to JA2 treatment at maturity. Double spray of jasmonic acid showed less stress symptoms in different antioxidant enzymes activities (GPX, APX and CAT), reduce percentage of disease incidence and severity as well as improve growth and yielding characters of chilli plant. Therefore application of Jasmonic acid in chilli could be a possible alternative of pesticide application and its two times exogenous spray (0.5mM) is most effective.

“…Alternatively, PPO may oxidize phenols similarly to POD (Constabel & Barbehenn 2008). Application of JA to tomato (Solanum lycopersicum L.) increased PPO activity, and these plants also reduced growth of the caterpillar Manduca sexta (Linnaeus, 1763), a Solanaceae specialist and the bioassay herbivore used in this study (Cipollini & Redman 1999). Protease inhibitors interfere with the ability of caterpillars to digest protein by inhibiting protease enzymes in their gut (Green & Ryan 1972).…”

“…Throughout its wide range, M. sexta feeds on a variety of plants in the genus Solanum including the two plants in this study (Madden & Chamberlin 1945, Yamamoto & Fraenkel 1960. Its growth can also be affected by the defensive proteins analyzed above (Cipollini & Redman 1999, Bosch et al 2014, making it an appropriate bioassay organism.…”

Background and aims-Arbuscular mycorrhizal fungi (AMF) are ubiquitous soil organisms that interact with plant roots and exchange soil nutrients for plant-derived carbohydrates, frequently resulting in growth and fitness benefits for plants. These benefits may be due partly to AMF effects on plants' resistance to insect herbivores, particularly through enhancement of induced defenses. Here we studied the impacts of AMF colonization on constitutive and induced resistance in two species of nightshades, Solanum ptycanthum and S. dulcamara. Methods-We used a factorial design manipulating AMF presence and jasmonic acid application to determine if constitutive and induced resistance differ in the presence and absence of mycorrhizae. We measured three protein-based chemical defenses and performed a bioassay by feeding leaves of experimental plants to a specialist herbivore, Manduca sexta. Key results-The presence of AMF influenced chemical defenses in S. dulcamara, including an interaction with jasmonic acid application for polyphenol oxidase activity. Solanum ptycanthum defenses were unaffected by AMF. Caterpillar growth was also unaffected by AMF but reduced by jasmonic acid treatments, indicating that, while AMF may influence certain chemical defenses in some plant species, this does not always translate to resistance against herbivores. Conclusions-Our results emphasize the context dependency of fungi-plant-herbivore interactions and suggest that mycorrhizal effects on plant defense may vary with other plant traits or life history strategies.

“…The accumulation of anthocyanins was decreased when the MJ treatment period was delayed in the sprouts co-treated with MJ and salinity ( Figure 6). In tomato plants, JA treatments induced defense responses against insect larvae including several defense-related oxidative enzymes activations in a plant age-dependent manner [54]. In red leaf lettuce, young leaves showed greater anthocyanin accumulation than did old leaves in response to MJ [23].…”

Methyl Jasmonate and Salinity Increase Anthocyanin Accumulation in Radish Sprouts

Plant secondary metabolites with antioxidant properties, such as anthocyanins, are considered to have an important commercial value for some crops. Although anthocyanin concentration increases in response to various stimuli in plants, the mechanism of anthocyanin accumulation under multiple stimuli is not yet well understood. Here, we examined the effects of methyl jasmonate (MJ) and salinity on anthocyanin accumulation in radish (Raphanus sativus) sprouts. MJ treatments induced anthocyanin accumulation, which was enhanced by simultaneous treatment with salinity (200 mM NaCl), accompanied by growth restrictions. Sprouts treated with salinity alone did not induce anthocyanin accumulation, although sprout growth was restricted. Co-treatment with MJ and salinity increased hydrogen peroxide, total phenol content, and radical scavenging capacity more strongly than was achieved when each treatment was applied singly. Accumulation of anthocyanin was dependent on NaCl concentration and light intensity. Changing MJ and salinity treatment periods had different effects on anthocyanin accumulation and growth restriction, indicating that these phenomena might be differentially regulated. These results may provide an effective anthocyanin accumulation method without reducing plant biomass.
