Hakuto that the rooting cofactor, which showed a strong synergistic effect with IAA on the root formation of mung bean cuttings, was present in the basal stem tissues and reached maximum level of content 4-7 days before the rooting followed by a decrease. Thus, the physiological meaning of the rooting cofactor is considered to be one of the factors regulating the rooting process. The extracts from fresh leaf tissues of chinese cherry (Prunus pauciflora Bunge), an easy-to-root species, had a high content of the rooting cofactor, which promoted the root formation on callus derived from wild peach shoot in vitro, and on the softwood cuttings of peach cv. Okubo with exogenous IBA. From these facts, the application of chinese cherry's rooting cofactor to cuttings may be an available technique on propagation of peach. On the other hands, high percentage of rooting was obtained with an oblique basal end surface of cutting and on Kanumatsuchi as bed soil, therefore these conditions appears to be essential ones on propagation by stem cuttings.}, pages = {11--20}, title = {モモのさし木繁殖に関する基礎的研究 V : 発根促進処理についての二, 三の知見(農学部門)}, volume = {34}, year = {1982}, yomi = {ゲンマ, ヒロシ and コジマ, キョウコ and スズエ, シゲノブ and ソバジマ, ヨシツグ} }
