Abstract

The purpose of this study was to investigate shooting and fruiting characteristics of persimmon 'Hachiya' affected by sub-zero temperature at early budding stage. The number of developed shoots, and the number of shoots with young fruits, and the shooting and fruiting of terminal buds of one-year-old branch (1YOB) were significantly decreased with the sub-zero temperature treatment (SZT). The number of shoots developed in the top of 1YOB decreased 47.2% due to SZT. The number of shoots with fruits was significantly decreased at 50% or higher in non-budding rate of 1-YOB. Especially the number of fruits (Y) at the three terminal buds of 1YOB was significantly affected by SZT and the non-budding rate (X) as Y = -0.145X + 12.950 ($r^2=0.4672^*$). Therefore, in the early budding stage of persimmon, when tree is affected by SZT ($-2^{\circ}C$, 3 hours), shoots growth is reduced and increase of 10% in non-budding rate reduces 1.4 of fruits per the three terminal buds of 1YOB.

본 연구는 감나무 '갑주백목'의 발아 초기에 영하의 온도 처리에 따른 신초 생육 및 착과 특성을 알아보기 위해 수행되었다. 1년생 가지 당 발생된 신초 수, 착과된 신초 수, 그리고 정단부의 신초의 생장 및 착과는 영하온도 처리에 따라 뚜렷이 감소하였다. 그리고 1년생 가지 정단부에서 발생한 신초의 착과 수는 영하온도 처리에 의해 47.2% 감소하였다. 1년생 가지의 착과 신초 수는 그 가지의 눈 고사율 50% 이상 가지에서 유의하게 감소하였다. 특히, 정단부 3개의 눈에서 발생한 착과 수는 영하온도 처리와 이에 따른 눈 고사율 차이의 영향을 뚜렷하게 받았다. 영하온도처리를 받은 1년생 가지의 눈 고사율(X)과 정단부 3개의 눈에서 발생된 과실수(Y) 간 Y=-0.145X+12.950($r^2=0.4672^*$)의 유의한 관계를 나타내었다. 따라서 감나무 발아초기에 영하 온도($-2^{\circ}C$, 3시간)의 영향을 받으면 신초 생장량이 감소되고, 눈 고사율 10% 증가함에 따라 1년생 가지(정단부 3개의 눈) 당 착과 수는 1.4개 감소되는 것으로 생각된다.
