摘要：

The anatomy of normal and hyperhydric in vitro shoots and leaves from micropropagated Simmondsia chinensis (Link.) Schn. (jojoba) was compared with that of seedlings (control plants). In vitro normal plantlets displayed good development and survived during the acclimatization stage. In vitro hyperhydric plantlets presented numerous anatomical defects, such as hypertrophy of the mesophyll and of the stem cortex, malformed non-functional stomata, epidermal discontinuity, and xylem hypolignification; they did not survive acclimatization. The study of the anatomical features of in vitro jojoba shoots and leaves allowed determination of the structural condition of the plantlets and prediction of which plantlet would survive the critical acclimatization stage.
