Abstract
딸기의 잿빛곰팡이병과 흰가루병을 방제하기 위해 개화기에 살균제 처리가 요구된다. 최근에 딸기에 등록된 살균제들이 딸기 화분 발아에 미치는 영향은 거의 알려지지 않았다. 따라서 본 연구에서는 in vitro 상에서 딸기 3품종의 화분에 대한 24종의 살균제와 6종의 친환경자재에 대해 발아에 미치는 영향을 조사하였다. 딸기의 화분은 18% sucrose agar 배지에서 $25^{\circ}C$로 처리되었을 때 쉽게 발아되었으며, '설향', '매향', '금향'의 평균 화분 발아율은 각각 15.3, 18.4, 30.7%을 보였다. Pyraclostrobin, azoxystrobin, kresoxim-methyl, dichlofluanid, iminoctadine tris, sulfur는 무처리구 대비 93.8% 이상의 화분 발아 억제가를 나타내었다. 반면, simeconazole과 procymidone 살균제의 화분 발아율은 영향이 가장 적었다. 이 in vitro 검정 결과는 딸기 재배농가의 개화기 살균제 선정에 대한 정보를 제공할 수 있을 것이다. Fungicide applications are required to prevent the strawberry from Botrytis fruit rot and powdery mildew that infect open strawberry flowers, however, their effects of fungicides on pollen germination of strawberry have been rarely documented, particularly those from recently developed active fungicidal ingredients. In this study we have evaluated the effects of 24 commercial fungicidal formulations and 6 organic materials on pollen germination in 3 strawberry cultivars using in vitro assays. Pollens from strawberry had higher germination rates on agar with sucrose of 18% and $25^{\circ}C$ than other tested conditions. Pollen germination rates of cvs. Seolhyang, Maehyang, and Kumhyang at 18% sucrose and $25^{\circ}C$ were 15.3, 18.4 and 30.7%, respectively. Pyraclostrobin, azoxystrobin, kresoxim-methyl, dichlofluanid, iminoctadine tris, and sulfur showed the strongest inhibitory efficacy with the germination rates of more than 93.8% compared to the no-fungicide control. Germination was not significantly affected by simeconazole and procymidone. This in vitro germination study may provide information useful for selecting fungicides in flowering stage to strawberry farmers.
