생장조정제 사용에 앞서 작물재배과정에서 꼭 알아둘 점이 있다면 (1) 생장조정제는 재배환경에 민감하게 작용하기 때문에 온도, 습도, 광등을 고려하여 정상생육 환경이 되도록 재배환경을 잘 맞춰줘야 약제발현 효과가 있으며 (2) 토양환경면에서 세포생리 기능이 정상적으로 분화발육 할 수 있을 때 약제 발현성을 높이기 때문에 비배관리면에 특히 유념해야 한다는 것이다.

This study was conducted to stable direct sowing cultivation with seedling growth promotion by plant growth regulator treatment in onion seed(Allium cepa L.) The emergence percentage of soaked seed in BA, GA$_3$, and kinetin solution were higher than control seed, and those were 93.0, 94.3, 93.8%, respectively. The plant height was significant elongation in growth regulators treated seed, and those effects were high GA$_3$, kinetin and BA in the order, and the extend were high as increasing the growth regulator solution concentration in GA$_3$ and BA, and that was reverse in kinetin. The No. of leaf was increased in growth regulators treated seed, and the extend were similar among the growth regulators. The No. of root was increased significantly in growth regulators treated seed, and the extend were high in GA$_3$, BA and kinetin in the order.

콩은 중요한 식량 작물로 단백질, 기름 및 이차대사산물인 이소플라본을 다량으로 함유하고 있다. 이소플라본은 폴리페놀의 일종으로 일부 암을 예방하며 심혈관 질환을 완화하는 데에도 도움을 준다고 알려져 있다. 콩에 인위적으로 식물호르몬인 ABA를 처리할 때 이차대사산물인 kaempferol의 함량이 증가한다고 보고 되었다. 따라서 이 연구는 식물 생장조정제 처리가 콩잎의 이소플라본 함량에 미치는 영향을 알아보기 위해 수행되었다. 연구는 밀양 남부작물부 유리온실에서 수행되었으며, 콩(품종:선풍)은 와그너포트 1/2000에 1주 2본 파종하여 재배하였다. Ethephone(500, 1000, 2000 ppm)과 ABA(100, 200, 400 ppm)를 사용하였으며 각각 R2, R5, R7기에 처리하였다. 처리 후 잎을 5일 간격으로 3회 채취하여 이소플라본 6종과 쿠메스트롤의 함량을 분석하였다. 초고성능 액체 크로마토그래피(Acquity UPLC H-Class system, Waters)를 사용하여 분석하였다. 이소플라본 함량은 R5 단계에서 전반적으로 높게 나타났으며, R2 및 R7 단계에서는 무처리와 유사한 수준을 보였다. ABA를 처리하였을 때 생장조정제 간의 차이가 에테폰보다 더 큰 것으로 나타났다. 쿠메스트롤 함량은 처리시간에 따라 R7, R5, R2 순으로 높은 것으로 확인되었으며, 처리시간이 지날수록 함량이 증가함을 알 수 있었다. 생장조정제 처리에 쿠메스트롤 함량은 ABA보다 에세폰 처리 시 더 높은 경향을 보였다.

This study was conducted to evaluate the effects of trinexapac-ethyl (TE) and prohexadione-calcium (PC) on the growth and turf quality of perennial ryegrass (Lolium perenne L.). Treatments were designed as follows; control (non-treatment), TE (TE 0.01 a.i. g·m^-2·100mL^-1), and PC (PC 0.01 a.i. g·m^-2·100mL^-1). Compared with control, turf color index and chlorophyll content of TE and PC treatments were not significantly different. As applied plant growth regulators (PGRs), shoot length in the TE and PC was decreased by 8.9-12.4% and 6.7-13.6%, respectively, and clipping yield by 44.4-45.8% and 40.6-40.9%. When evaluated with the growth of shoot length after applying PGRs, residual days of TE and PC were 43.6 and 37.9 days after treatment of PGRs (DAT) in the 1st experiment (July 29-August 26), respectively, and 38.3 and 39.5 DATs in the 2nd experiment (September 30-October 28). These results indicated that an application of TE or PC decreased shoot length and clipping yield in the perennial ryegrass, and their residual time was about 40±3 DATs. Perennial ryegrass applied with PGRs like TE and PC was not significant seasonal difference, and might be not phytotoxic.
