  • When sowing green peas in the autumn, proper seedling stands and growth quantity should be secured before winter begins. Also, for proper acclimatization, injuries caused by low temperatures, frost or high temperatures in the P.E. film during mulching, should be avoided during the regeneration period; that being early spring. The days required for growth in each stage in Yeosu are shorter than those in Naju because Yeosu has high temperatures during the growth period. Furthermore, in Yoesu, it was observed that there were more effective branches as well as effective and attached node positions on the branches. The first pods on the main stems and effective branches were observed to be higher than those in Naju. The number of pods per plant and the number of seeds per pod in Yoesu was greater than for those in Naju and the pod length was longer as well. Considering the missing plant rate, growth, and green pod yield, the optimum sowing date for the green pea was mid-November in both location. The stable acclimatizing date for the green pea was early March when the highest yield can be acquired due to a lot of effective branches and pods per plant and with the lowest missing plant rate and rate of injury in acclimatization.

  • This study was conducted to establish the optimal condition for plant regeneration and acclimatization from somatic embryos of Panax ginseng. Cotyledon segments of Panax ginseng produced primary and secondary somatic embryos when cultured on MS and WPM media supplemented with 7% sucrose. To induce plantlet conversion, cotyledonary somatic embryos were cultured on WPM solid medium with $GA_3$ at various concentrations (1~30 mg/L) for 4 weeks. Plantlets were transferred to 1/2 WPM solid medium with $GA_3$ at various concentrations (0~5 mg/L) and 0.5% activated charcoal for shoot and root elongations. Elongated plantlets further developed into well-developed leaf and root system on 1/3 SH medium with 0.5% activated charcoal under ventilation condition for 5 months. The highest survival rate to soil was 75% when plantlets were regenerated on 1/3 SH medium without sucrose under ventilation condition.

  • This study was carried out to investigate the optimum composition and concentration of medium for the acclimation of the shoots derived from bioreactor culture of Scrophularia buergeriana. Rooting and growth of the shoots cultured in bioreactor for 4 weeks were better on liquid full strength MS medium while one-tenth of MS medium was good for rooting and growth of the shoots cultured in bioreactor for 6 weeks. Leaf expansion was more effective in the shoots cultured for 6 weeks on solid MS medium than in those cultured for 4 weeks. No leaf expanded in liquid medium. Vitrification rate was higher in full strength solid MS medium than in half strength MS medium. It is concluded that acclimation of the shoots is more effective on the half strength solid MS medium containing 1.2% agar.

  • In order to develop effective acclimatization methods for Aralia elata plantlets regenerated from somatic embryos, various acclimatizing conditions were compared regarding both survival rate and growth of the plantlets. The plantlets were transplanted into plastic boxes containing artificial soil in the presence of either several levels of MS liquid media, distilled water, 2% sucrose or 0.1% hyponex solution. They were then cultured by spraying of distilled water twice a week and maintained in the normal tissue culture room. Perlite was proved to be better than vermiculite on survival rate and growth of the plantlets. As the size of perlite (larger than 0.2 cm in diameter) increased, both the survival rate and growth of the plantlets improved. Among the various MS liquid media and different aqueous solutions tested, distilled water appeared to result in the best survival rate and growth. MS media were also effective in increasing survival rate and supporting growth when diluted to 1/4 and/or 1/8. The acclimatized plantlets could be transplanted directly onto the nursery bed and grown normally. The above results suggest that plantlets regenerated from somatic embryos of Aralia elata be effectively acclimatized using a plastic box containing perlite with distilled water treatment.

  • Nerine was originated from South Africa and around 30 kinds of species are distributed in worldwide. In present study we have characterized the condition of storage and growing conditions on the bulb propagation of Nerine by the tissue culture. Result indicated that the percentage of decrement, decay and sprouting of bulblets in the tissue culture was high at the higher temperature compare to lower temperature. The optimum conditions for storage and time were 12 weeks at $15^{\circ}C$ which were having 86.4% sprouting rate. The sprouting rate at different temperature and acclimation time, using bulblets in the tissue culture, were optimum at early June when temperature is relatively higher($22^{\circ}C$) that facilitate to breaking the dormancy. Growth characteristics and capacity of photosynthesis of Nerine were better at red and blue mixed lightness.

  • This experiment was conducted to clarify the effects of physiological properties in culture media on the proliferation and the acclimation of bulblets of several kinds of lilies cultured in vitro. Proliferation rate of bulblets from bulblet of Oriental hybrid ‘Marco Polo’, ‘Casa Blanca’ and Asiatic hybrid ‘Jolanda’ was higher in solid MS media compared with bulblets from scale Acclimation rate of regenerated bulblets was high in solid media which was pre-cultured in vitro, compared with liquid media. Sprouting rate of bulblets from bulblet was higher than bulblets from scale.

  • This experiment was carried out to know the effect of media and agar concentrations, aeration and growth regulators on rooting and acclimatization of the shoots harvested from bioreactor culture in Rehmannia glutinosa. Half MS media with 1.2% agar improved rooting and acclimatization of shoots. Shoots were effectively acclimatized and rooted well in case of aeration by using membrane filtered vessels. Shoots acclimatized in vessel with membrane Inter were healthier and had higher ex vitro survival rate than those without membrane Inter on plug tray. Addition of paclobutrazol 0.3-0.4 mg/L, to acclimatization media enhanced shoots growth and root development.
