Abstract:

A qualitative analytical method for avocado rooting promoters (ARP) has been developed based on gas chromatography (GC) of silylated samples. Leaves of easy and difficult to root clones of Laurus nobilis L. and Magnifera indica L. were extracted and analyzed for ARP components and for ARP-like activity. Avocado rooting promoter compounds II and/or 21 can be detected in leaf extracts of both easy and difficult to root bay laurel. It was found that ARP-like activity was higher in the easy to root than in the difficult to root plants as manifested in the mung bean rooting bioassay. Compounds II and/or 21 were found in the easy to root mango clone but not in the difficult to root one. However, ARP-like activity was similar in the two extracts. © 1991.
