In Vitro Seed Germination and Seedling Growth of Staurochilus Ramosum (Lindl.) Seidenf

Abstract

A comparative study on in vitro seed germination and seedling development of Staurochilus ramosum (Lindl.) Seidenf. was carried out in vitro. Four basal media namely KC, MS, PM and VW media were used as half strength, full strength and full strength supplemented with 0.5mg/l BAP and 0.5mg/l NAA and solidified with agar. Response like protocorm like bodies (PLBs) initiation, seed germination and seedlings development on different basal media were varied distinctly. Full strength PM medium supplemented with 0.5mg/l BAP and 0.5mg/l NAA showed better response within 6 weeks of culture. The overall result indicates that PM medium was more effective than KC, MS and VW media for initiation of germination, PLBs formation and plantlets development.
