Cut flower vase life is extended when plants are produced with microbial biostimulants
Biostimulants can improve the quality of flowering plants
The addition of beneficial microorganisms during the production of zinnia plants did not alter plant growth or scheduling as we had originally predicted, however there was a very large positive influence on the postharvest performance of the cut flowers. Treatment with beneficial microorganisms increased the vase life of zinnia cut flowers. One treatment, OSU2, resulted in cut flowers that lasted 10 days longer than the flowers from the untreated plants. Further studies are needed to determine how these differences are influenced by the addition of cut flower preservatives and to evaluate different cut flower species.
