Background: The objective of the present study was to investigate the effect of storage conditions on the growth of Saururus chinensis (Lour.) Baill. rootstock.
Methods and Results: Rootstocks of S. chinensis were stored in either soil or vermiculite that had been treated with a control treatment, diluted wood vinegar (50 or 100-fold), DF-100 (50-fold), or 1-naphthylacetamide and at 5℃ or 15℃. After 8 weeks, the stored roots were planted in the field, and both plant height and leaf number were observed after transplantation. The greatest number of leaves (5.60 ± 0.80) was produced by roots that had been stored in soil treated with 100 fold dilution of wood vinegar and at 5℃. Meanwhile the maximum plant height (6.92 ± 0.78 ㎝) at 30 d after transplanting was observed for rootstocks that had been stored in soil treated with the 100 fold dilution of wood vinegar and at 15℃, whereas the maximum plant height at 60 d after transplanting (26.46 ± 0.71㎝) was observed for rootstocks that had been stored in soil treated with the 100-fold dilution of wood vinegar and at 5℃. Therefore, the storage of rootstocks in soil treated with the 100-fold dilution of wood vinegar and at temperatures at or below 5℃ was most effective, and it can be used to prevent the decay of roots during the postharvest management of S. chinensis rootstocks.
Conclusions: The results of the present study indicate that, among the parameters examined, the storage of roots in soil that had been treated with the 100-foil dilution of wood vinegar is the most effective method for improving the growth of S. chinensis.
