Background: Licorice is a major medicinal crop used in most herbal remedies in Korea. Establishing efficient planting techniques for the licorice rhizome (stolon) requires, examining the agronomic characteristics of licorice rhizome (stolon) using different planting standards such as thickness, length, and planting methodology.
Methods and Results: Various cutting lengths (3 ㎝, 5 ㎝, and 7 ㎝) and sizes (4 ㎜ - 6 ㎜ and ≥ 7 ㎜ in thickness) of licorice rhizome (stolon) were propagated. To optimize the planting methods, the licorice rhizome (stolon) cuttings were planted upright (90°), oblique (30°), and level (180°).
The aboveground bud number and growth characteristics were investigated. The 7 ㎝ length rhizome (stolon) with a thickness of 4 ㎜ - 6 ㎜ produced one bud. The thickest cutting (≥ 7 ㎜) all produced two buds except the 3 ㎝ length of rhizome (stolon). The plant heights were superior when grown from the thickest cuttings. However, there was no significant difference in growth between the different cutting lengths of the same thickness.
Conclusions: To optimize planting, the cutting should be ≥ 7 ㎝ in length and ≥ 7 ㎜ (biennial) in thickness and planted at 30° (oblique method).
