본 연구는 전정방법이 ‘홍이슬’ 포도나무(Vitis vinifera L.)의 생장, 과실품질, 그리고 생산량에 대하여 어떠한 영향을 미치는 지를 규명하기 위하여 2012년과 2013년에 수행되었다. 단초전정, 중초전정, 단초+장초전정, 그리고 단초전정+장초유인의 네 가지 전정방법이 시험처리에 이용되었다.
1. 단초전정 +장초유인은 신초발생수를 가장 크게 증가시켰고, 빈가지수를 감소시키면서 착과수를 증가시킨 반면에 단초전정은 신초수를 감소시키면서 신초장과 빈가지 수를 증가시켰다.
2. 단초전정 +장초유인은 과실수량을 크게 증가시켰고, 과방과 과립의 특성은 처리 간에 유의성 있는 차이가 나타나지 않았다.
3. 단초전정 +장초유인은 과실의 당도와, 당산비, 과피의 적색을 나타내는 a*값을 크게 증가시켰다.
4. 단초전정은 과실의 안토시아닌 함량을 크게 감소시켰다.
The study was investigated how the pruning methods affected growth, and fruit quality and production of ‘Hongisul’ grape (Vitis vinifera L.) trees in years 2012 and 2013. Four pruning treatments included; short pruning, half-short pruning, short + long pruning, and short pruning+long bending. Short pruning+long bending treatment mostly increased number of current year’s shoot, with reduction of number of non-bearing shoots and increase of fruiting while short pruning reduced number of shoot, increased length of shoot and number of non-bearing shoots. Fruit yield was the highest on short pruning + long bending. Fruit characteristics of cluster and berry were not significantly affected by pruning methods. Fruit SSC and SSC/acidity ratio were increased by short pruning + long bending. Fruit surface color of a*, representing for redness, was improved by short pruning + long bending. Anthocyanin contents on fruit peel were the lowest by short pruning. Fruit gross production was the highest on short pruning + long bending, with the lowest observed for short + long pruning.
