The rooting activity of pinus sylvestris l. extracts as related to the rooting ability of cuttings

, : The rooting activity of pinus sylvestris l. extracts as related to the rooting ability of cuttings. Phyton (Buenos Aires) 50(1-2): 41-48

The activities of partitioned extracts from cuttings of Pinus sylvestris L. with different rooting potential as a function of age and physiological state of the donor plant, were tested in the mungbean bioassay. Extracts from cold stored pine shoots were also examined. The organic neutral fractions of the extracts had influence on rooting potential in the bioassay. Both sub-fractions F-1 and F-2, obtained by column chromatography with PVPP, of the neutral fraction, revealed a special incidence in the rooting response, because their rooting activities were higher in shoots collected at the beginning of the growing season, in shoots from younger plants, and in cold stored shoots.
