Abstract
This studies were conducted to investigate the effects of hexaconazole on growth of watermelon(Citrullus lanatus Schrad) and ethylene evolution from gourd(Lagenaria siceraria Standl). While foliar application of hexaconazole exhibited inhibition effect, little or no inhibition was found in the plants treated with soil drench application. The plant height and number of internode in watermelon were significantly inhibited at 7 days after treatment(DAT), but no significant difference was found at 42 DAT. No significant difference was found in site of female flower setting when treated with hexaconazole. The length of branch was significantly inhibited at the 2nd or the 3rd internode. It was suggested that the inhibition of stem elongation was related with application timing of the chemical. Hexaconazole increased ethylene evolution more effectively at earlier stage of gourd, but after 5 DAT ethylene evolution was decreased.
Hexaconazole의 처리가 수박의 생육 및 박의 ethylene 발생에 미치는 영향을 검토한 결과를 하면 다음과 같다. 약제처리 방법에 따른 수박 생장의 억제효과는 경엽처리가 현저하게 효과적인데 반하여 토양관주 처리에서는 효과가 없거나 미미하였다. Hexaconazole 경엽처리시 수박생장은 약제처리 7일후에는 농도가 높으면 높을수록 신장, 마디수가 억제된 반면 약제처리 42일후에는 무처리와 차이가 없었다. Hexaconazole 처리시 수박의 암꽃 착화위치는 착과부위인 제 2번 암꽃까지의 길이생장 및 마디수에는 아무런 영향이 없었고, 측지길이에 미치는 영향은 제 2, 제 3마디에서 현저하게 억제되었는데 이는 처리시기와 밀접한 관련이 있을 것으로 판단된다. Hexaconazole 처리시 박의 ethylene 발생량은 처리농도가 높을수록 ethylene 발생량이 증가하는 경향을 보였으며 약제처리 5일까지는 계속 증가하다가 이후 감소하였다.
