Metabolic Significance

Apples cv. Jonagold were harvested at the beginning of October and stored at 0°C until treatment between the beginning of December and the end of January. Methyl jasmonate (JA-Me) at the concentration of l,0, 0,5, 0,1, 0,05, and 0,01% in lanolin paste were applied to the surface ofintact apples. During five days from treatment, samples of cortex with skin (area about 2,0 cm<sup>2</sup>) were cut off at a depth of about 2 mm and used for determination of ethylene production, ACC oxidase activity and respiration determined as CO<sub>2</sub> evolution. The production of endogenous ethylene was highest at mid-January ( 100, 280, and 250 nl/g*h at December, mid-January, and the end of January, respectively). During December and at the beginning of January, JA-Me initially ( 1 -2 days after treatment) stimulated ethylene production and then the production was inhibited. The lower concentration of JA-Me caused initially the greater stimulation and then Iower inhibition of ethylene production. However, at the time of maximum production of endogenous ethylene (mid-January) and later. stimulatory effect of JA-Me disappeared. The effect of various concentrations and time of application of JA-Me on ACC oxidase activity had similar trend as endogenous ethylene production. Methyl jasmonate stimulated respiration and this effect was dependent on JA-Me concentration and independent on time of application. The metabolic significance of these findings is discussed.

ABSTRACT The knowledge about the role of jasmonates in ethylene production by pathogenic fungi is ambiguous. In this study, we describe the effect of methyl jasmonate (JA-Me) and gums formed in stone fruit trees on the growth and in vitro ethylene production by mycelium of Verticillium dahliae and Alternaria alternata. Methyl jasmonate at concentrations of 100, 250 and 500 μg·cm-3 inhibited the mycelium growth of V. dahliae and A. alternata, proportionally to the concentrations used. After 8 days of incubation, JA-Me at concentration of 500 μg·cm-3 limited the area of mycelium of these pathogens by 7-8 times but did not entirely inhibited the pathogen growth. Addition of gums produced by trees of cherry and peach to a medium containing 40 μg·cm-3 JA-Me did not influence the mycelium growth of V. dahliae, but gums of plum and apricot trees stimulated mycelium growth, in comparison to JA-Me only. Methyl jasmonate at concentrations of 2 and 40 μg·cm-3 stimulated the ethylene production by mycelium of V. dahliae and A. alternata. It is possible that methyl jasmonate stimulated ethylene production in mycelium of these pathogens through interaction with some fractions of galactans formed during hydrolysis of agar. The lack of interaction of JA-Me with polysaccharides of stone fruit trees gums concerning ethylene production was documented and it needs further explanation.

Radish Seedlings

Radish sprouts and young seedlings are considered important dietary vegetables in Asian countries. In this study, we investigated the levels of glucosinolate and anthocyanin accumulation in radish seedlings in response to light and methyl jasmonate (MeJA) treatments. MeJA facilitated the accumulation of glucosinolate and anthocyanins under light conditions. The glucosinolate and anthocyanin contents in the radish seedlings that were exposed to light after MeJA treatment were higher than those of the seedlings that were grown in the dark without MeJA. At a concentration of 100 μM, MeJA led to the greatest accumulation of the most glucosinolates under both light and dark conditions. Under light conditions, the levels of glucoraphenin, glucoerucin, and glucotropaeolin accumulation were 1.53-, 1.60-, and 1.30-fold higher, respectively, than those of the control. Remarkable accumulations of glucobrassicin were observed under light conditions (4.4-, 6.7-, and 7.8-fold higher than that of the control following the application of 100, 300, and 500 μM MeJA, respectively). The level of cyanidin in the 300μM MeJA-treated seedlings was double of that in the control without MeJA treatment. The highest level of pelargonidin was observed after treatment with 500 μMMeJA under light conditions; this level was 1.73times higher than that in the control. A similar trend of anthocyaninaccumulation was observed in the radish seedlings following MeJA treatment under dark conditions, but the levels of anthocyanins were considerably lower in the seedlings that were grown in the dark. Our findings suggest that light and low concentrations of MeJA enhance the accumulations of glucosinolates and anthocyanins during the development of radish seedlings.

ABSTRACT Methyl jasmonate (MJ) is an endogenous regulator that can influence fruit ripening and the defense system against pathogens. This work verified the influence of this regulator on postharvest physiology, control of anthracnose and physicalchemical attributes of ‘Kumagai’ guava (Psidium guajava L.). Guavas harvested at mature-green and ripe stages were treated with 0, 1 and 10 μmol∙L−1 MJ as gas in hermetic containers (200 L) with air circulation for 24 h. Fruit were inoculated with Colletotrichum gloeosporioides spore suspension (105 spores∙mL−1) 24 and 48 h after treatment. During ripening, at 25 °C and 80 – 90% of relative humidity, respiration, ethylene production, anthracnose incidence, severity and quality of guavas were assayed. Data were subjected to analysis of variance and means, compared by Tukey’s test (p ≤ 0.05 and 0.10). The application of 1 and 10 μmol∙L−1 MJ had little influence on ripening of ‘Kumagai’ guava with a slight increase in respiration, ethylene production and yellowing of fruit harvested at ripe stage. Treatments with 1 and 10 μmol∙L−1 MJ did not reduce the severity and incidence of C. gloeosporioides when applied in fruit harvested at ripe and mature-green stages and inoculated 24 or 48 h after MJ treatment. In conclusion, the MJ treatment, at 1 and 10 μmol∙L−1 concentrations, had little influence on ripening and did not control anthracnose in ‘Kumagai’ guavas.
