PLANT-REGENERATION FROM LEAF-DISKS OF PEANUT AND PIGEONPEA - INFLUENCE OF BENZYLADENINE, INDOLEACETIC-ACID AND INDOLEACETIC-ACID AMINO-ACIDCONJUGATES

The influence of indoleacetic acid (IAA) and some IAA-amino acid conju gates in combination with benzyladenine (BA) on in vitro shoot regener ation from leaf discs of peanut and pigeonpea was investigated. The fr equency of shoot regeneration and average number of shoot buds produce d was dependent on the type of auxin present in the medium. Highest fr equency of plant regeneration in peanut was induced by BA in combinati on with IAA or IAA-l-alanine, while in pigeonpea BA in combination wit h IAA or IAA-l-aspartic acid produced best results. Four hundred plant s of peanut and 25 plants of pigeonpea were transplanted to soil.
