Journal of Zhejiang University (Agric Life Sci) , 2007, 33(2) :202-206 A stract: In order to explore the functionary echanis of plant growth-pro oting rhizobacteria ( PGPR) CH 1and CH2 to cucu ber growth and quality, the seed ger inating, greenhouse pot planting and physiological and bioche ical ethods was e ployed to study the effects of CH 1and CH2 on growth and physiological etabolis of cucu ber. Results showed that PGPR CH1 and CH2 obviously pro oted ger inating of cucu ber seeds, root and plant growth, as well as the superoxide anion- producing rate, contents of H O and MDA in roots an
