ENHANCED PLANT-REGENERATION IN GRAIN AND SWEET SORGHUM BY ASPARAGINE,PROLINE AND CEFOTAXIME

Cefotaxime (50 and 100 mg/l), a cephalosporin antibiotic and the amino acids asparagine and proline (200 mg/l) enhanced the production of em bryogenic callus, increased the frequency of plant regeneration, and d elayed the loss of regeneration potential in immature embryo-derived c allus cultures of Sorghum bicolor (L.) Moench. Although these compound s did not promote callus induction or growth of callus, they influence d plant regeneration considerably in 10 low responding genotypes of gr ain and high anthocyanin containing sweet sorghums.
