다래(Actinidia arguta) 및 교잡종 다래(A. arguta × A. deliciosa)의 수관층위에 따른 광합성, 엽 그리고 과실의 특성 변화 = Changes of Photosynthesis, Leaf and Fruit Characteristics of Actinidia arguta and Hybrid Kiwi (A. arguta × A. deliciosa) According to Crown Layer

다국어 초록 (Multilingual Abstract)

This study was carried out to investigate the change of photosynthesis, leaf and fruit according to crown layers in Actinidia arguta and hybrid kiwi. Photosynthesis rate (PPFD 1,000 μmol·m-2s-1) were 5.82, 7.11, 9.54 μmol CO2(m-2s-1) at lower, middle, and upper position, respectively in 3 layer cultivation type. The length and area of leaves collected from lower position have lager value than upper position. The fruit quality of A. arguta and hybrid kiwifruit increased with increasing crown height. A linear correlation (R2=0.72, 0.89 and 0.98) was shown between fruit weight (Boeun 4, Injea 16 and HM3) and the height of crown layer(layer 1, 2, and 3). From the results, we can suppose that the tree of the upper position of crown layer in the cultivation of A. arguta and hybrid kiwifruit produce high quality fruit due to its high photosynthesis ability.
