Abstract

Amsonia ellipotica (Thumb.) Roem. & Schult. has less than 10 native places nationwide and is evaluated as an endangered species (EN) on the Korean Red List, so systematic breeding and cultivation methods are required. This study was carried out to establish an effective method for seedling production in A. elliopotica that can be developed as a genetic resource conservation and new ornamental material. This experiment was performed by varying the seedling production container (72, 105 and 128 cell trays), number of seeds sown in a cell (1, 2, and 4 per cell), soil type [horticultural soil and neutralized peat-moss: perlite mixed in 3:1, 4:1 (v:v)], additional fertilizer concentrations (0, 250, 500 and 1000 ㎎/L) and shading degrees (0, 55 and 75%). As a result of the study, growth increased with the increased in measuring capacity per cell of sowing container. According to number of seeding growth, sowing one seed per cell was the best. Seedling growth increased as the treatment concentrations increased, higher growth was in 1000 ㎎/L. On the other hand, during the shading treatment, growth significantly decreased regardless of shading degrees.
