Effect of planting material on growth and seed rhizome yield of ginger(Zingiber officinale Roscoe)

摘要

Meristem derived ginger plants cultivar Khing Yai were micropropagated in vitro. Small rhizomes were produced from these plantlets under different photoperiods(8, 10, 12, 14, and natural daylength (12.01-11.19 hrs.)). The performance of small rhizomes produced from micropropagated plantlets as compared with conventionally planting big rhizomes and direct transplanting of micropropagated plantlets was evaluated from growth, rhizome yield and rhizome branching.
