elongated quickly, but many of the newly formed organs
presented necrotic spots (Fig. 2e). Overall, M12 was the
worst medium in terms of promotion of shoot growth and
elongation.
Non-rooting shoots were kept in their elongation media
beyond the 30-day checkpoint, and individually transferred
to rooting medium once they reached a minimal length of
2 cm. During the 6-month period considered, M13 was the
medium that induced elongation in more shoots
