摘要:
Explants of jojoba (Simmondsia chinensis(Link) Schn.) from randomly selected plants were propagatedin vitro. On modified Murashige‐Skoog (MS) medium supplemented with 1 mg/litre BA (N6‐benzyl‐adenine) there was a 4.6‐fold increase in shoot numbers at 30 days. After 15 days on modified MS medium supplemented with 3 mg/litre IBA (indolebutyric acid) c. 25% of the shoots had developed roots. The best exflasking survival rate of the rooted plantlets (90%) was observed when the plantlets were transferred to an organic mixture, Agrosoil™. Subsequent growth rates in Agrosoil™ were higher than in other potting media tested. On the other hand, the response of each clone was highly variable, some exhibiting 75% root formation at 60 days while others displayed little response.
