How should licorice seeds be treated? Introduction to common treatment methods
How should licorice seeds be treated? Is there anyone who can help explain? Licorice seeds generally begin to germinate at 10-15°C, and germinate fastest at 15-20°C. Old seeds have a reduced germination rate. One of the biggest characteristics of licorice is that it exhibits hard-seededness, usually with a hard seed rate of 70-90%, making it very difficult for seedlings to emerge after sowing, so in production, seeds...
How should licorice seeds be treated? Is there anyone who can help explain?Licorice seeds generally begin to germinate at 10-15°C, and germinate fastest at 15-20°C. Old seeds have a reduced germination rate. One of the biggest characteristics of licorice is that it exhibits hard-seededness, usually with a hard seed rate of 70-90%, making it very difficult for seedlings to emerge after sowing. Therefore, when propagating by seed in production, the seeds must be treated before sowing.
Zhongdi Network has compiled several methods for treating licorice seeds, listed above for readers' reference.
Method one: soaking seeds in boiling water.
Method two: soaking seeds in concentrated sulfuric acid.
Method three: grinding with crushed glass.
Method four: milling with a rice mill. Among these, milling with a rice mill gives the best results. Generally, a few days before sowing, mill the seeds 1-2 times with a rice mill until the seed coat is scratched, but the seed coat must not be broken. Note that seed treatment must be carried out a few days before sowing; treating too early affects the germination rate. If the purchased seeds have already been treated and you do not know how long ago they were treated, or if there are insect marks on the surface, it is best not to use them, because the germination rate will be low.
