Conservation for endangered perennial Solanum maximowiczii Koidz following on the dam construction

Abstract

To establish the mitigation methods for the endangered perennial Solanum maximowiczii Koidz, the seed sowing test, the transplanting test, the transplanting test of their sticking shoots and the test for preventing the feeding damages were examined. Our results indicate that the individuals that were grown until their diameter at the ground level reached more that 1.0 cm are suitable for transplanting to the natural sites. Further, those individuals can be flowered and fruited. However, those developed individuals should be transplanted the site where are surrounded with the equipments that can prevent the feeding damages. Thus, the transplanting those developed individuals to the sites within the equipments that can prevent the feeding damages is thought to be the effective way to mitigate the speceis.
