Abstract

The effects of foliar spray and soil drench application of triazole chemicals (diniconazole, myclobutanil, difenoconazole, tebuconazole, bitertanol, hexaconazole) on growth and flowering control in zinnia were investigated. For foliar spray application of tebuconazole, diniconazole and bitertanol on 'Dream Land Rose', plant height was decreased but tebuconazole gave the best result for dwarfing. Diameter, fresh and dry weights of flower were markably decreased at high concentration of tebuconazole. However, days to flowering was not affected by chemicals tested. For 'Dream Land Scarlet', plant height was decreased with all chemical treatments. Tebuconazole severely decreased plant height, in particulas. Diniconazole hastened flowering. For soil drench of 'Dream Land Rose', plant height was decreased by diniconazole and mycrobutanil, but diniconazole was more effective for plant height decrease. Flowering was hastened by diniconazole in both 'Dream Land Rose' and 'Dream Land Scarlet'. Plant height of 'Dream Land Scarlet' was decreased by all chemicals tested. Flowering was not occurred at $300mg{\cdot}L^{-1}$ myclobutanil with severe suppression of stem growth.

본 실험은 triazole계 화합물을 백일홍 'Dream Land Rose'와 'Dream Land Scarlet'에 경엽살포 또는 토양관주처리를 하여 생육 및 개화에 미치는 영향을 조사하기 위하여 수행하였다. 경엽살포처리에서 'Dream Land Rose'의 초장은 tebuconazole, diniconazole, bitertanol에서 크게 감소하였으며 특히, tebuconazole이 가장 큰 왜화효과를 보였고 지상부 생체중도 가장 적었다. 꽃의 직경, 생체중, 건물중도 tebuconazole 고농도에서 현저하게 감소하였다. 한편, 개화소요일수는 약제처리에 의한 영향을 받지 않았다. 'Dream Land Scarlet'의 초장도 모든 처리에서 감소하였고, 특히 tebuconazole에서 현저한 감소를 보였다. 개화소요일수는 diniconazole에서 단축되었다. 토양관주처리에서 'Dream Land Rose'의 초장은 diniconazole과 myclobutanil에서 감소하였으나 diniconazole이 더 효과적이었다. 개화소요일수는 diniconazole에서 단축되었다. 'Dream Land Scarlet'의 초장은 모든 처리에서 감소하였으며, mycrobutanil $300mg{\cdot}L^{-1}$에서 극심한 억제현상을 보여서 개화가 이루어지지 못하였다. 개화소요일수는 diniconazole에서 증가하는 경향을 보였다.
