Effect of adding wood vinegar on cucumber (Cucumis sativus L) seed germination
Abstract
Wood vinegar, a liquid by-product that was obtained from the condensed vapor generated during the biomass pyrolysis, had been reported as plant growth promotor, but the impact on the plant seeds was still not clear. Thus, we investigated the effects of wood vinegar on the germination and seedling growth of cucumber seeds through the germination experiments. The results showed that the different diluted wood vinegar addition showed no significant difference in the germination rates of cucumber seeds compared to those of the CK treatment (P > 0.05). However, the added wood vinegar at the 10000-time dilution significantly increased the root length and dry biomass of cucumber by 20.9 % and 5.92 %, respectively (P < 0.05). Therefore, the wood vinegar at an optimal time of dilution could be used a promising soaking agent for the seeds germination, and further enhance crop yields.
