Summary

This study was conducted during 2011 and 2012 to evaluate the effect of 1-aminocyclopropane-1-carboxylate (ACC)
deaminase-containing, N2-fixing and P-solubilizing bacteria on the yield and morpho-physiological parameters of
strawberry. A total of 8 applications at the trial set, with four water regimes were randomly distributed into the
pots. The diminishing water supply caused a gradual decrease in the plant growth, chlorophyll content and berry
yield, accompanied by increasing activities of drought stress markers such as total phenolics content (TPC), trolox
equivalent antioxidant capacity (TEAC), malondialdehyde (MDA) content, hydrogen peroxide (H2O2), glutathione
reductase (GR), glutathione S-transferase (GST), catalase (CAT), peroxidase (POD), superoxide dismutase (SOD)
and ascorbate peroxidase (APX) in the leaves of strawberry. The multi-trait bacteria also increased plant growth and
yield as well as TPC, TEAC, antioxidant enzymes (GR, GST, CAT, POD, SOD and APX) activity, phytohormone
(GA, SA and IAA) and the contents of N, P, K, Ca, Fe, Mn, Zn and Cu, but decreased MDA and H2O2 contents
which may contribute in part to activation of physiological and biochemical processes involved in the alleviation
of the effect of drought stress.
