Use of Desirability Function Method in Optimization of Regeneration and Callus Induction of <i>Alhagi camelorum</i>

Abstract

In this study, the desirability function approach was used to simultaneously optimiz e multiple factors. The vari ables evaluated were combinations of growth regulators, media and organs in affecting the organogenesis of Al hagi . In the first step of this study, various experiments were carried out in order to optimize the callus induction and its growth. The highest rate of callus induction was achieved from the leaf segment on MS medium supple mented with 3 mg·l -1 BAP + 6 mg·l -1 NAA. Moreover, the highest rate of regeneration was recorded on MS me dium supplemented with those 4 mg·l -1 BAP using for leaf segments. The optimized condition of roots induction per shoot was observed in the 1/4 MS medium without activated charcoal and supplemented with 0.25 mg·l -1 IAA. The well rooted plantlets were acclimatized and successfully established into soil where 70% plantlets were survived . The data indicate that media, BAP, and NAA levels may be manipulated to increase or decrease qual ity factors chosen.
