。Table 2 Cultivation test of radish (Test Example 2) (4) Discussion According to Table 2, germination is improved by coating the seeds with a mixture of chitin powder and chitosan powder 2 low-viscosity chitosan powder. It can be seen that the degree of germination is superior in the following order: chitosan powder, chitin powder, low viscosity chitosan powder, and control.
