Abstract

This work was done to study the rooting performance of strawberry cv sweet Charlie under in vitro conditions. Healthy microshoots were collected from in vitro plantlets (1.0-1.5 cm long) grown in hormone free basal MS medium and placed in MS media containing BAP (0-1.0 mg/l) and (IBA 0-1.0 mg/l) for shoot elongation and root proliferation. The results showed that the higher number of newly formed shoots was observed in the medium containing 0.5 mg/l BAP and 0.5 mg/l IBA. The shoot and root lengths of newly formed shoots were high (>4.5 cm) in hormone free medium and also media with 0.5-1.0 mg/l IBA than the other tested media. Further, it was noted that more than ten roots per plantlet were recorded in MS media containing 0-1.0 mg/l IBA and also there was no significant variation (P>0.05) in number of roots between them. MS media supplemented with 0-1 mg/l IBA concentrations could be used for rooting of strawberry microshoots under in vitro conditions.
