Abstract
This study was conducted to determine the effects of embryo age, growth regulators, low temperature treatment on regeneration, plant growth, and heading in immature embryo culture of Barley. Shoot and root development was more in older than in younger excised embryos, and more in a medium without kinetin than in one with kinetin. The rate of survival was higher on medium without growth regulators and lower on medium with kinetin 5 mg/L because of retarded plant growth. Embryo age and media did not completely replace low temperature treatment. Twenty- and 14 day-old embryos responded by flowering after 4 weeks of vernalization. Embryo culture at 14- and 20 days after anthesis coupled with 4-week cold treatment shortens generation time of barley. When 20 day immature embryos of barley (cv. Olbori) was treated low temperature treatment for 4 weeks, the rate of heading was better than the other treatment.
본실험은 대맥의 미숙배 배양을 통한 육종기간을 단축하기 위하여 미숙배 배양시 식물체 유도, 생육 및 출수에 영향을 미치는 생장조절물질, 배의 성숙정도 및 저온처리효과를 구명하고자 실시하였으며 그 결과는 다음과 같다. 1. 미숙배 배양으로부터 줄기의 유도에는 생장조절물질이 첨가된 기본배지도 효과적이었으며, Kinetin 0.5mg/1와
