The internal levels of indole-3-acetic acid (IAA) and polyamines (PAs) and the metabolism of indole-3-butyric acid (IBA) were studied in relation to the in vitro rooting process of two pear cultivars, the easy-to-root Conference and the difficult-to-root Doyenne d'Hiver. Doyenne d'Hiver required about a 10 times higher concentration of IBA to achieve a rooting percentage similar to that of Conference. One- or two-day exposures to IBA were sufficient to stimulate rooting but with different… CONTINUE READING
