섬현삼의 종자발아와 분화재배를 통한 현지외 보전

Abstract

This study was conducted to identify the overall phase of biology through seed germination and pot cultivation of endangered and endemic species, Scrophularia takesimensis which is offering the biological basic data for ex situ conservation. Seed germination rate was the highest at 66% when seed were pre-chilled(30 days) and soaked in distilled water and then sown in bedsoil under 50% shading condition. Also we examined the effects of seedlings size, type of soil and shading condition for pot cultivation. Seedlings size as a ‘samll’(plant height 2.5 cm, number of leaves 4, leaf width 1.2 cm, leaf length 1.7 cm) was the best and efficiency quality in bedsoil under non-shading condition with the growth characteristics of plant height(39 cm), number of leaves(29), leaf width(9.1 cm), leaf length(5.9 cm), root length(14.2 cm) and fresh weight(above ground/below ground; 23/5.3 g) and dry weight(above ground/below ground; 4.6/1.3 g). Futhermore there was 94% or more flowering and fruiting in this condition. In this study, we have established the cultivation and ex situ conservation of S. takesimensis. Therefore propagated plants(over 3,000 individual) could be used for not only various research but also ex situ conservation.
