Abstract
|
|
|
|
Kinetin (4.7×10^5M) and 6-benzylaminopurine (2.22×10^5M) were found to increase ca. 1.5-fold putrescine content in corn grown in meidum containing kinetin and 6-benzylaminopurine (6-BAP) for 3 days whereas kinetin was found to decrease ca. 30% spermidine and spermine, respectively. KCI (3×10^3M) was found to decrease more than 50% putrescine content. After germination, ornithine decarboxylase activity was observed to increase constantly whereas arginine decarboxylase activity remained constant, suggesting involvement in putrescine biosynthesis. 6-benzylaminopurine was shown to increase more activities of arginine and ornithine decarboxylase than kinetin when they were added to medium.
