| Abstract: | Leachate extracts from senescent Gingko biloba leaf compost, separated by paper chromatography, and analyzed for biological activity using the soybean callus bioassay indicated that cytokinin-like compounds which co-eluted with zeatin and/or dihydrozeatin are released from decomposing leaves. Both leachate and leaf compost extracts obtained in the 5th month of composting were fractionated using HPLC. A cytokinin-like compound, which co-eluted with iso-pentenyladenosine was detected. |
