버즈풋 트레포일 (Lotus corniculatus L. cv. Empire) 종자로부터 직접 캘러스를 유도하고, 형성된 캘러스로부터 식물체를 재분화하는 조건을 확립하였다. 캘러스 유도시 사용한 SH (Schenk and Hildebrandt), MS (Murashing and Skoog), N6 (Chu) 배지중에서 SH 배지가 캘러스 유도에 유리한 것으로 나타났으며, 캘러스 유도 및 중식시에는 2,4-D 3 m g / ℓ 을 첨가한 조건이 가장 효율이 좋았다. 식물체 재분화 조건은 BOi2Y 배지에서 20일 간격으로 계대배양하며 재분화를 완성한 조건 2가 더 좋았으며, 캘러스로부터 완전한 식물체로 재분화되는데 필요한 시간은 약 60일이었다.
