Abstract:
An experiment was carried out to examine the Effect of plant growth regulators on rooting behaviour of in vitro strawberry cv. Winter Star. It was observed that in direct regenerated microshoots with application of IBA (1.5 mg/ l) in 1/2 MS media takes minimum days (8.08) for root initiation followed by RM₂ (8.92) and RM5 (9.74) with maximum rooting percentage (94.35 %) was observed in RM₃ (1/2 MS + 1.5 mg/ l IBA) followed by RM₂ (89.65 %) and RM5,(84.50 %). Maximum number of roots/ explant (8.49) followed by RM₂ (7.83) and RM₅ (6.75), and length of roots (5.37 cm) was also recorded in 1/2 MS + IBA (1.5 mg/l) followed by 1/2 MS + IBA (1 mg/l) media.
