Auxin type, gel concentration, rooting, and survival of Cheiranthera volubilis in vitro

Auxin promoted rooting in 70% to 95% of in vitro shoot cultures of Cheiranthera volubilis compared with 25% on auxin-free medium. The type of auxin in the medium affected root morphology, with, in turn, affected plantlet survival on transfer to soil. IBA in the medium caused thickened roots or callusing, with poor survival of rooted plantlets (10% to 40%). NAA or NOA alone stimulated thread-like root growth and increased survival (60%) (...)
