抄録
The growth-promoting activity of the exudates from of various plant species was compared with that of their ashes in the Amaranthus hypocotyl elongation test. Changes in the activity by the burning of exudates were markedly different among plant species (Fig. 1). Based on the effect of burning, tested plants were classified into three type;<br>(a) The ashes showed a loss or decrease of the activity (Cyperus iria, Amaranthus viridis, Amaranthus lividus, Chenopodium album, Amaranthus caudatus, Veronica persica, Latuca sativa, Petroselinum crispum, Cryptotaenia japonica, Daucus carota, Echinochloa crus-galli, Allium tuberosum, Spinacia oleracea, Oryza sativa).<br>(b) The ashes showed a much greater activity than the exudates (Cucurbita moschata).<br>(c) The promoting activity of the exudates was not affected by the burning (Lepidium sativum, Brassica oleracea, Archtium lappa, Asparagus officinalis, Fagopyrum esculentum, Helianthus annuus, Avena sativa, Abelmoschus esculentus, Pisum sativum).<br>The relationship between the growth-promoting activity of the exudates or the ashes and seed weight was examined in various plant species. The activity of the ashes showed a positive correlation with the seed weight (r=0.83), unlike that of the exudates (r=0.66) (Fig. 2).<br>These results suggest that inorganic substances as well as organic substances such as lepidimoide act as growth-promoting factors in the exudates from plant seeds. The organic substances may be physiologically released from seeds, whereas inorganic substances may be released physically.
