Streptomyces jingyanesis 5406细胞分裂素混合剂能明显地降低小美旱杨树溃疡病(Dothiorella gregariaSacc)的发病率.用100倍稀释液浸泡24小时处理,发病率为未处理的对照组的12.5%.用不同浓度的混合剂分别处理杨树溃疡病原菌和杨树枝条表明,这种混合剂能对杨树溃疡病菌有一定的抑制生长的作用:而且能明显地促进杨树干部愈杀组织形成的作用。试验还证明,在愈伤组织形成和发展过程中,过氧化物酶(PRO)活性始终处于较低水平.
The Streptomyces jingyanesis 5406 cytokinin mixture significantly reduced the incidence of Dothiorella gregaria Sacc, which was treated with a 100-fold dilution for 24 hours at a rate of 12.5% of the untreated control The different concentrations of the mixture of agents for the treatment of poplar canker and poplar branches show that this mixture can inhibit the growth of Poplar canker to a certain extent, and can obviously promote the formation of more dead shoots in poplar stems. Experiments also demonstrated that peroxidase (PRO) activity was consistently low during callus formation and development.
