Abstract

Mechanical stimulation induce the morphological changes in plants. In this study, we investigated the growth changes of tomato seedlings applicated to mechanical stimulation. The brushing treatment was used for mechanical stimulation. The brushing treatment interval was 2 hr using transfer device attached acrylic film from 10 days after sowing. Growth parameter of tomato seedlings were measured 3-day intervals to investigate the growth changes during brushing treatment. The plant height and leaf area were decreased in brushing treatment than the control, and the fresh and dry weights of shoot didn't have significant difference in the control and brushing treatment. The total root length and root surface area were increased in brushing treatment compared than the control, and root volume has no significant difference in the control and brushing treatment. In conclusion, these results suggest that the application of brushing treatment on tomato seedling make shorten plant height and well-development root morphological characteristics.

기계적 자극은 식물체의 형태적 변화를 유도하는 것으로 알려져 있다. 본 연구에서는 기계적 자극을 적용한 토마토의 육묘기 동안의 생육 변화를 확인하기 위해 수행되었다. 브러싱 처리가 기계적 자극으로 이용되었으며, 아크릴이 부착된 이송장치를 이용하여 2시간 간격으로 파종 후 10일 이후부터 처리를 진행하였다. 브러싱 처리 동안 생육 변화를 확인하기 위해 3일 간격으로 생육을 조사하였다. 초장과 엽면적은 브러싱 처리에서 대조구에 비해 감소하는 결과를 보였으며 지상부의 생체중과 건물중은 대조구와 유사한 값을 보였다. 총 근장과 지하부 표면적은 브러싱 처리에서 대조구에 비해 증가하였으며, 지하부 부피는 대조구와 브러싱 처리가 유사한 값을 보였다. 결론적으로 토마토 공정묘에 브러싱 처리는 지상부의 생육 감소를 유도하였으며 지하부의 형태적 발달을 증가시키는 것으로 판단된다.
