Abstract: | Availability of amino acids for the growth of rice callus tissuewas examined by supplying various kinds of amino acids to thetissue separately or in combination. When an amino acid wassupplied alone as the sole source of nitrogen, only the followingfive amino acids were found to favour the growth of callus tissue;arginine, alanine, asparagine, glutamine and proline. In combinationwith other acids, both AHCH and CMAA were very effective instimulating the growth of tissue, but EHCH was inhibitory. Whenmethionine or arginine was excluded from the CMAA medium, callusgrowth on the medium was reduced significantly. The effect producedby omitting methionine suggested that some amino acid interactionwas involved in this instance. (Received February 19, 1970; ) |
