In total,33 compounds of volatiles emitted from three developmental stage plants were separated and identified,and quantitatively analyzed by the internal standard addition method. All of the samples of volatile were found to be rich in monoterpenes and sesquiterpenes. β-phellandrene and caryophyllene predominated in the volatiles of the leaves of plants at the two-and ten-leaf stages. Furthermore,(E)-2-hexenal were the dominant components in the volatiles emitted from anthesis plants. The results of volatiles analyzed show that the compositions varied depending on the developmental stages. The volatiles emitted from crushed tomato leaves of plants at the anthesis stage had the most strongly inhibitory activity against the spore germination and hyphal growth of Botrytis cinerea and Fusarium oxysporum,followed by ten-and two-leaf plants. However,the activity of volatiles,emitted from the leaves of plants at the two-leaf stage,in inhibiting F. oxysporum was greater than B. cinerea.展开更多
