음나무 (Kalopanax septemlobus) 체세포배를 이용한 인공종자 조제 및 발아 = Germination of Artificial Seeds by Encapsulation of Somatic Embryos of Kalopanax septemlobus with Alginic Acid

다국어 초록 (Multilingual Abstract)

Artificial seeds were produced by encapsulation of somatic embryos of Kalopanax septemlobus and investigated the effects of alginic acid concentration, size of somatic embryos, additives in capsules and nursery seedbeds for germination. The most suitable concentration of alginic acid was 3% for germination of encapsulated seeds. Germination was suppressed at higher concentration more than 3% alginic acid. For germination of artificial seeds, 1/2 MS medium with 0.02% activated charcoal was effective. There was no significant differences on the germination among the different size of somatic embryos. Additives in hydrated capsule was very important for germination and post-germinative growth of artificial seeds. Germination was severly inhibited in hydrated capsule containing only distilled water. Both sucrose and MS medium addition in hydrate capsule was effective for germination of artificial seeds. When artificial seeds were transferred to soilbed, germination rate was high in perlite containing 3% sucrose but very low in perlite with only water. These results indicate that nursery additives in both hydrate capsules and soilbeds was important for germination of artificial seeds in Kalopanax septemlobus.
