Abstract

We aimed to investigate the effects of Calendula officinalis and Echinacea purpurea extracts in terms of growth parameters, antibacterial activity and phenolic profile in tomato infected by Clavibacter michiganensis subsp. michiganensis (CmmT7). A significant difference was observed in E. purpura extract, indicating the highest effects on plant height (27.25 cm), fresh plant weight (28.45 cm), root length (24.42 cm), and root weight (6.74 g) (p<0.05). Moreover, Calendula officinalis and Echinacea purpurea extracts showed significant inhibitory activity against CmmT7 (p<0.05). Among phenolic compounds, the only chlorogenic acid amounts were varied in the tomato seedlings leaves with C. officinalis extract (K3) + CmmT7, E. purpurea extract (E3) + CmmT7 and CmmT7 (p<0.01). Moreover, chlorogenic acid amount was approximately 9 times higher than in CmmT7-treated leaves when compared to control. The results showed that application of the extracts of these plants had a significant influence on bacterial canker and growth parameters.

金盏菊和紫锥菊提取物对番茄细菌性溃疡病病原菌密歇根锁杆菌的抑菌活性研究。michiganensis

研究金盏花和紫锥菊提取物对受密歇根克拉维杆菌感染的番茄生长参数、抗菌活性和酚类成分的影响。michiganensis (CmmT7)。紫癜提取物对植物株高(27.25 cm)、鲜重(28.45 cm)、根长(24.42 cm)和根重(6.74 g)的影响最大(p<0.05)。金盏菊和紫锥菊提取物对CmmT7有显著的抑制作用(p<0.05)。在酚类化合物中，只有绿原酸含量在山茱萸提取物(K3) + CmmT7、紫皮提取物(E3) + CmmT7和CmmT7的番茄幼苗叶片中存在差异(p<0.01)。此外，绿原酸含量比对照高出约9倍。结果表明，应用这些植物的提取物对细菌溃疡病和生长参数有显著影响。
