説明
The present paper deals with the effects of Spergula arvensis L. buried into soil and its aqueous extracts on the emergence and growth of crops. Also allelopathic substsnces from Spergula arvensis L. were identified by paper, thin layer and high performance liquid chromatography. The results obtained are summarized as follows:<br>1. Seed emergence and growth of vegetables (Brassica rape L., Lycopersicum esculentum L. and Raphanus sativus L.) were remarkably inhibited by leaves and stems of Spergula arvensis L. buried into the soil of pots and by sprays of the solution extracted with water (Table 1).<br>2. The aqueous extracts inhibited the elongation of the second leaf sheath in rice plants and it was shown that the degree of inhibition became severe with increasing concentrations of the extracts (Table 2).<br>3. When the acidic fraction from methanol extracts was developed by paper chromatography with iso-propanol: ammonia: water (10:1:1) and bioassayed using rice plants, three zones with inhibitory properties were located at Rf 0.0-0.2, 0.3-0.8 and 0.9-1.0 on the chromatogram (Fig. 2).<br>4. The active zones (Rf 0.0-0.2) showing the strongest inhibitory effect among the three ones were eluted with methanol and the inhibitory substances were identified by paper, thin layer and high performance liquid chromatography. The structure of two inhibitory substances appeared to correspond to that of caffeic and ferulic acids (Fig. 3, 4, 5, 6).<br>5. Authentic substances, caffeic and ferulic acids inhibited the elongation of the second leaf sheath in rice plants. The degree of inhibition increased with the concentration of the substances (Fig. 7).
