PGR (mg/l)	Nature of response
0	No response, explants died
1.0 BAP	Shoot bud induction, No callus
1.0 TDZ	Shoot bud induction along with callus formation at the base of the explant
1.0 2-ip	Bud break in some explants, yellowing of explant, necrosis
1.0 ZEA	Induction of shoot buds in some explants, wrinkled appearance
1.0 IAA	Callus formation in some explants at the base, shoot bud like protuberances at the surface of some explants
1.0 NAA	Initiation of callus formation, unhealthy appearance
