STUDIES ON THE EFFECT OF AGE OF IN VITRO GROWN SEEDLINGS ON REGENERATIVE RESPONSE OF EXPLANTS IN TOMATO (Solanum lycopersicum)

摘要

Studies on the effectiveness of age of in vitro grown seedlings on regenerative response of explants derived from them were conducted in tomato (Solanum lycopersicum L.) cv. PKM-1. The results revealed that cotyledons and hypocotyls of 10 days old seedlings were found to be superior compared to explants collected from 8, 12, 14 days old seedlings when MS medium is supplemented with BAP 1.5 mg/L + Kinetin 1.0 mg/L. These findings could be well exploited for further development of quick regenerative and transformation protocols for the tomato cv.PKM-
