Abstract: Effects of three antibiotics on inhibition of Agrobacterium Rhizogenes LBA4404 and 15834, bud formation and growth of tea plant were studied. The results showed that cefotaxime sodium and timentin can completely inhibit the growth of Agrobacterium LBA9402 and 15834, however, carbenicillin only inhibit LBA9402 bacterium but not 15834 bacterium. Bud regeneration and growth are significantly inhibited by cefotaxime sodium and carbenicillin treatment. There is no significant difference between Timentin (≤400βmg·L-1) treatment and control without antibiotics on bud regeneration and growth of tea culture seedlings. Timentin is a good alternative antibiotic to eliminate Agrobacterium tumefaciens in tea plant genetic transformation system.
