Abstract

With the aim to determine a possible relationship between somatic embryogenesis and some metabolic contents in embryogenic and non-embryogenic calluses of sugarcane (Saccharum sp. var CP-5243), the present study was carried out. Embryogenic callus has more soluble proteins, free proline, proteolytic activity, soluble sugars, and invertase, and lower putrescine/(spermidine + spermine) than non-embryogenic tissue. Non-embryogenic callus has a higher peroxidase and gallic acid level, lower dry matter/fresh matter ratio, and more gross fat compared with embryogenic callus.
