Abstract
ABSTRACTCitrus jambhiri (Rough lemon) is popularly preferred for rootstock for cultivated species of Citrus. Tissue culture is an appreciable technique for mass-multiplication of plant propagules. In this communication direct regeneration of plantlets of Citrus jambhiri Lush. were obtained from cotyledons, roots and leaves. Most of the cotyledon (96%) enlarged on medium supplemented with 50 mg/L of casein hydrolysate. Few of those enlarged cotyledons responded to direct regeneration of shoots. Maximum shoot per responded cotyledon was 32. Conversely, the health of the plantlets were poor with semi-cylindrical leaves. Most of them dried on maintenance medium or on rooting medium ad died. Plantlets regenerated on medium supplemented with IAA in combination with IBA were healthy and they established on maintenance medium and rooted on rooting medium. Direct regeneration was also obtained from leaf on MS medium supplemented with 0.50 mg/L of dicamba. Our finding concluded that tissue culture tools may be used for direct regeneration of plantlets from different explants of C. jambhiri to obtained true-to-type plant propagules.
