Abstract
Abstract The rooting activity of water extracts of cuttings of chestnut ( Castanea sativa Mill.) and willow ( Salix viminalis L.) was studied throughout the year by the bean rooting test. The chestnut extract nullified the rooting activity of 10 −5 M IAA, but on the whole it did not modify the rooting pattern of the bean cuttings. The willow extract increased rooting and showed a rhythm in the content of endogenous growth substances. IAA was found at the time when the extract showed the strongest rooting activity. The extract from willow contained two synergistic root‐promoting fractions with the R f 's of 0.0–0.2 and 0.6–0.8 in isopropanol: ammonia: water. The latter one promoted rooting without added IAA. In this fraction a high amount of catechol was detected. No clear correlation was found between the ability to induce roots and the total phenol content in the two species.
