Óleos essenciais como potenciais elicitores botânicos no tratamento de sementes de soja

Abstract

Soy is one of the main Internal gross Product of the country, your productivity is directly linked to the national economy for this care since the beginning of your cycle is paramount. The search for pest and disease control by alternative methods that are less harmful to the environment and the living beings as a whole, significantly increases year after year.This work aimed to evaluate the ability of elicitora essential oils of jasmine, cherry, patchouli and citronella in germination and seedling development and how resistance inducer after seed treatment in soybeans. The work was conducted on the Campus of the Federal University of technology-Paraná of Dois Vizinhos. First essential oils were applied through seed treatment in soybean seeds, in concentrations of 1%, 2% and 4%. Assessed what percentage of germination and development after the seed treatment. The experiments were subjected to normality test and occurring need will be modified. After, analysis of variance (F test) and averages compared by Tukey test with 5% probability, using the statistical program Sisvar®. Evaluations of germination can be noted that essential oil of jasmine and cherry doesn't differ from the results between their concentrations. Patchouli essential oil in 1% and 2% concentrations do not differ from the witnesses. Citronella essential oil inhibits germination in all concentrations used. As the assessment of development of radicle, essential oilsof jasmine and cherry no different statistically between the concentrations. Patchouli essential oil inhibits development of radicle as increased oil concentration occurs in the treatment. It is concluded that essential oils of jasmine and cherry will have the same end result independent of the concentration used. Essential oil of patchouli does not differ statistically concentrations for germination, but development of the radicle concentration indicated is 1%.
