This study was conducted both in field and greenhouse
conditions at Atatürk University, College of Agriculture,
Erzurum, Turkey, during 2004 and 2006. The objective of this
study was to determine the effect of some bacteria isolates
on root formation, root length and dry matter content of
roots of mint (Mentha piperita L.). Mint and Agrebacterium
rubi (strain A16), Burkholderia gladii (strain BA7),
Peseudomonas putidea (strain BA8), Bacillus subtilus (strain
OSU142) Bacillus megatorium (strain M3) were used as rooting
agent, respectively. The highest rooting percentage was
obtained by application of A16 (88.70; 89.85%), M3 (86.12;
91.15%) and BA8 (87.27; 87.77%). Overall, the lowest was
observed in controls (79.31 and 76.96). Root length was
greater when cuttings were treated with BA7, A16 and M3
compared to the other treatments. Mint cuttings inoculated
with M3 had more dry matter content than control and the
other treatments in both experiments. Rooting performance,
root length and dry matter content of root, cuttings of mint
treated with bacterial solutions showed better performance
than control cuttings in both experiments. In addition, when
evaluated bacteria strains were compared, M3 was found more
effective than the others on the examined properties.
