Abstract

Stone fruits are well known for their high nutritional value. Therefore, in horticulture, the micropropagation of suitable rootstocks is vital for their cultivation. The aim of the present study was to improve the micropropagation protocol of Myrobalan 29C (Prunus cerasifera Ehrh.) rootstock using shoot-tip culture. Murashige and Skoog (MS) basal medium containing 2 mg L-1 6-benzylaminopurine (BAP) and 0.05 mg L-1 gibberellic acid (GA3) resulted in the highest number (14.3) of multiple shoots. However, a greater shoot length (2.0 cm) was attained when GA3 was excluded from the MS medium and the concentration of BAP was reduced to 1 mg L-1. Root induction was best in ½MS medium containing 0.5 mg L-1 indole-3-butyric acid (IBA), 0.5 mg L-1 α-naphthaleneacetic acid, and 10 mL L-1 (≈13 mg L-1 Fe) ethylenediamine di-2-hydroxyphenyl acetate ferric with 7.0 roots per explant. On the other hand, the longest root (12.5 cm) was obtained from increased concentration to 1 mg L-1 of IBA. The establishment of a well-defined micropropagation protocol will lead to further biotechnological improvement of this crop.
