Plant Growth-Regulating Activity of Pyroligneous Acid : I. Effect of pyroligneous acid on the growth of rice seedlings

[摘要] This paper reports the effect of pyroligneous acid, which is produced by the pyrolysis of wood, on the growth of rice seedlings. 1. The growth of rice seedlings was promoted by the soil treatment with pyroligneous acid (Table 1 and Table 2). 2. The rooting activity of rice seedlings was accelerated by the treatment with pyroligneous acid prior to transplanting (Table 3 and Table 4). 3. The erectness of rice seedlings was increased by the application of pyroligneous acid (Fig. 1 and Fig. 2).
