영문 초록

As the fundamental studies for the population of Myagropsis myagroides, the effect of plant hormones on the regeneration for the primary, secondary lateral and receptacle segments were investigated. At high concentration(lO-³M and lO-⁴M) of plant hormones inhibits from regenerating and lower concentrations advance the regeneration. The most effective concentrations of hormones on the primary lateral segments are 10-6M of kinetine, IAA, NAA and 10-5M of 2, 4-D in order, meanwhile in the secondary lateral segment 10-6M of NAA, 10-9M of kinetine, l0-7M of IAA, and l0-5M of 2, 4-D in order. The net regeneration rates of primary and secondary lateral segments which are measures by the wet weight are 124.1% and 228.9%, respectively. The influence of apical dominanace on the primary lateral segments decreases, on the other hand, increases in the secondary lateral segments because of the distance from the apex. Especially, the secondary lateral segments treated with below 10-5M plant hormone are matures with receptacle of small branching by the regenerated brnaching.
