In vitro regeneration and callus induction of Oryza sativa L. Var. MRIA 1 / Nor Yasmin Mohamad Fauzi
A study was conducted to determine the effects of different plant regulators (PGR) towards in vitro regeneration and callus induction of new Malaysian rice variety of Oryza sativa L. var. MRIA 1. Intemode explants of 4-week old of aseptic seedlings were selected for in vitro regeneration and a total...
