In Vitro Mass Propagation and Economic Effects of Bioreactor Culture in Ever-bearing Strawberry 'Goha'

초록

This study was conducted to compare various culture methods and evaluate economic feasibility of each method for mass propagation of new ever-bearing strawberry 'Goha'. Four different methods such as semi-solid culture, solid culture, liquid suspension culture and bioreactor culture were compared. The solid culture and bioreactor culture showed the shortest and longest root length, such as 3.6 cm and 8.3 cm, respectively. Fresh weights of plants cultured in bioreactor were 2,261 mg, which were heavier than those of cultures. Dry weights of plants cultured in bioreactor were the heavier compared to those in other cultures. The number of axillary bud developed in bioreactor was seven, but axillary bud was not developed in other cultures. Production cost through bioreactor culture was calculated to be 303 won per plant which was 542 won less than that of solid culture. As a result, we found that the bioreactor culture was the most cost effective culture method for in vitro mass propagation in new ever-bearing strawberry 'Goha'.
