Última Detection of Somaclonal Variation in Micropropagated and Acclimatized Plantlets of Oryza sativa MRQ 74 from Stem Explants Planta Daninha SALEH,A.; TAHA,R.M.; MAHMAD,N.; ELIAS,H.; HAMID,H.A.A.. ABSTRACT: In plant tissue culture system, the excessive supply of plant growth hormones may inhibit further growth and development of the regenerants and sometimes it may induce somaclonal variation. In this study, the optimum concentration of plant growth hormones for in vitro regeneration of Oryza sativa L. cv. MRQ 74 was identified and subsequently the occurrence of somaclonal variation of regenerated plantlets was determined through cytological analysis of in vivo and in vitro grown plantlets. MS media supplemented with 0.1 mg L-1 BAP in combination with 0.1 mg L-1 NAA was found to be the optimum concentration for shoots and roots induction of Oryza sativa L. cv. MRQ 74. Plantlets derived from MS media supplemented with 0.5 mg L-1 2,4-D showed higher... Tipo: Info:eu-repo/semantics/article Palavras-chave: Plant growth hormones; Oryza sativa L. cv.

Dwarf Bush Planta Daninha MOHAMED,N.; TAHA,R.M.; RAZAK,U.N.A.A.; ELIAS,H.. ABSTRACT: An efficient protocol for in vitro flowering was successfully established for Impatiens balsamina cv Dwarf Bush, an important medicinal plant, through tissue culture techniques. Shoot, stem and petiole explants obtained from 4 week-old aseptic seedlings cultured on MS medium supplemented with different concentrations of plant growth regulator (PGR) were used for in vitro flower induction. Gibberellic acid (GA3), benzylaminopurine (BAP) and kinetin (Kin) treatment singly applied in MS media (pH 5.8), could all stimulate flowering at 23-26 oC with photoperiod of 16 hours light and 8 hours dark. It was observed that shoot explants were more responsive than stem explants in floral formation. Regeneration was achieved via direct organogenesis. For...
