Abstract

This study was established on which germanium (Ge), known as one of the functional nutrients, treatment is the most effective method for increasing Ge uptake and contributing flowering development in the pruned branches in the winter. Ge treatment included foliar application, soil fertigation, trunk injection, and the three-combined application. Ge concentration in the pruned branches was greater on the three-combined treated trees, and Ge treated branches had greater Ge concentrations than the control. Pruned branches grown in the solution culture had greater bud weight and bud scale number on the Ge treated trees than the control. Ge treatments increased flowering per branch and flower number per bud as well as improved resistance of the freezing temperature damage. Overall, there were no consistent results of all the variables by the Ge application methods.

본 연구는 기능성 성분으로 알려져 있는 게르마늄을 '신고' 배나무에 처리 방법을 달리 했을 때 어떤 처리방법이 동계전정 된 가지에 게르마늄 흡수를 증가시키며 화아형성에 기여하는지에 대해서 조사하였다. 게르마늄 처리는 엽면살포, 토양 내 관주, 수간주입, 그리고 세가지 복합처리를 포함하였다. 전정 된 가지 내 게르마늄 함량은 복합처리구에서 가장 높았으며 게르마늄 처리 모두 대조구 보다 높은 함량을 보였다. 수삽된 전정가지 당 눈의 중량과 발생 된 인편의 수는 게르마늄 처리구에서 대조구보다 높은 경향을 나타냈다. 게르마늄 처리구는 개화율과 화총 당 꽃수를 증가시켰으며 저온 피해에 대해 대조구보다 유의적으로 낮은 양상을 보였다. 전체적으로 게르마늄 처리방법에 따른 수체에 나타나는 효과는 일관성이 없었다.
