Bta A603 +1) – 1) 20.67 ± 1.542) ab 3) –1)
Bta Ab12 + – 11.36 ± 2.20 b –

Btk E911 + – 14.69 ± 3.16 b –
Btk ABTS351 + – 27.40 ± 1.63 a –
1) “+”: positive reaction; “–”: negative reaction.
2) The concentration (mean ± SD) of IAA in each culture medium was determined by comparing with a standard
curve.
3) Values which are followed by the same letter are not significantly different at a level of 5% according to Tukey’s
studentized range test.

1) “–”: negative reaction.
2) Urease reaction: ++ moderate, +++ strong, ++++ very strong.
3) Concentrations of chitinase (mean ± SD) were determined using the filter paper disc agar diffusion method.
