e1“A chemically defined medium did not reveal the GA3 response, that is a remarkable growth promoting phenomenon in callus tissues by the interaction of 2, 4-dichrolophenoxyacetic acid (2, 4-D) and GA3 in the YE containing medium”

Other claims from this paper (11)
- Association In a chemically defined medium the kinetin effect on shoot formation in Aichi asahi callus disappeared.
- Intervention effect Increasing GA3 concentrations did not produce a GA3 response on Tan ginbozu callus growth in a chemically defined medium.
- Intervention effect Kinetin alone did not produce a GA3 response on Tan ginbozu callus growth in a chemically defined medium.
- Intervention effect Single amino acids did not produce a GA3 response in a chemically defined medium.
- Intervention effect L-lysine and L-threonine slightly induced a GA3 response in a chemically defined medium.
- Intervention effect Adding YE and CH to a chemically defined medium induced a GA3 response in Tan ginbozu callus.
- Intervention effect A mixture of amino acids made the GA3 response appear conspicuously in a chemically defined medium.
- Association Kinetin had a promoting effect on shoot formation in Aichi asahi callus cultured in CH medium.
- Association GA3 had an inhibitive effect on shoot formation of Aichi asahi callus cultured in CH medium.
- Mechanism A mixture of many amino acids is required for the GA3 response and for kinetin activity on organ formation in rice callus.
- Mechanism Callus growth and shoot formation are assumed to be closely connected with amino acid metabolism.
