During the 1995/96 growing season, Fusarium graminearum Schwabe, a pathogen of various winter cerals and corn, was isolated from soybean seeds produced in the Northern region of the state of Santa Catarina, Brazil, in an area where susceptible crops have been cultivated in previous years. This fact demanded studies to prove the association of the fungus with the soybean crop. Twenty seven monoascosporic cultures of the fungus isolated from soybean seeds and one from wheat seeds were used in this study. Inoculation of F. graminearum was done by the toothpick method and by wheat seeds colonized with the fungus. Only the toothpick method was effective to cause infection in inoculated plants. In this method, it was determined that the period of incubation of the toothpick in culture media containing the fungus did not affect the results of the inoculation. On the other hand, the age of the plants at the inoculation time was a factor that affected the infection rate of inoculated plants. Twenty-three-day old plants showed the highest infection rates. Inoculation of the 28 isolates to soybean cultivars 'BR-16' and 'FT-Abyara' showed that 'BR-16' was more susceptible than 'FT-Abyara' Although all isolates were able to infect the plants after inoculation, they did not kill the plants or transmitted the fungus systemically to the new seeds. The results of this study indicate that Fusarium graminearum may occur in plants and seeds however it is not pathogenic to soybean. |

Abstract: Plant resistance inducers are cost-effective and environmentally pleasing strategies of plant protection to mitigate biotic and abiotic agents threatening food safety and energy security. We, accordingly, present jasmonic acid and k-phosphite as low-cost strategies to enhance productive yield and technological quality of sugarcane crop. Exogenously treatment of the sugarcane variety SP81-3250 consisted of carrying out foliar application of jasmonic acid at 1, 1.5 and 2 ml L-1 and K-phosphite at 2, 4 and 6 ml L-1 before crop flowering. Interestingly, both systemic phytorregulator and foliar fertilizer at the lowest doses significantly improved contents of total soluble solids and sucrose, as well as productive yield of fermentable sugars. Jasmonic acid could promote growth and development by triggering either non-enzymatic or enzymatic mechanisms in the host self-defense system to support of external stresses, including herbivory by sugarcane-borer. K-phosphite could improve crop performance by not only releasing water-soluble inorganic ions like phosphorus and potash, but also by signaling synthesis of phytoalexins. Purity of cane juice and productivity of stalks sharply decreased, as the doses of the plant-resistance inducers increased. Jasmonic acid and k-phosphite at unbalanced endogenous levels could inhibit physiological ripening and specific enzymatical activity of alkaline invertases and sucrose-phosphate synthase, thereby influencing bioavailability of sucrose. The lower the sucrose content, the poorer the technological quality of sugarcane crop. The conclusion is, therefore, jasmonic acid and K-phosphite at lower doses prove to be effective induced resistance techniques to produce richer feedstock, with potential to produce ethanol fuel and refined sugar in sugar-energy plants.
