The beneficial effect of rhizopseudomonad strains on the growth of the barley cultivar Iban as a function of the storage time under laboratory conditions was evaluated. The beneficial rhizopseudomonad strains were preserved on slants of Modified King Medium B (MKB) at 28 °C and transferred every 2 weeks. After 6 months of storage most strains lost their beneficial effect on plant growth. Cold shock treatment enabled some strains to recover their beneficial effect on plant growth. Evidence is presented that there is a relationship between recovery of the stimulatory effect of certain rhizopseudomonad strains on plant growth and recovery of the capacity to colonize roots and to express antifungal activity.
