초록
본 연구는 야간조명 하에서 수목이 효율적으로 생장하는 방법을 모색하고자 LED 색온도에 따른 광합성 전자전달 효율을 검증하였다. 가로수와 조경수로 도시환경에 많이 식생하는 겹벚나무를 대상으로 White 색온도를 비춘 수목과 Warmwhite 색온도를 비춘 수목, 그리고 무처리 수목을 대상으로 건전도를 비교하였으며, 연구방법으로는 엽록소 형광반응 (OJIP)을 활용해 LED광원 색온도 조건에 따른 광 스트레스 광생리지표 분석을 통해 광화학반응 해석과 건전성 평가를 하였다. 엽록소 형광반응 (OJIP)을 분석한 결과는 모든 처리구에서 처리 후 115일인 생육후기로 갈수록 낮아졌으며, White 광처리구와 Warmwhite 광처리구에서 J-I구간의 전이 과정 중 생육후기의 형광량이 증가하여 광계I전자전달효율은 감소된 것을 알 수 있었다. 따라서 전자전달효율인 RE1O/CS 및 RE1o/RC 모두 감소되었다. 이 중 White 광처리구는 Warmwhite 대비 형광량의 증가폭이 컸으며, PITOTALABS는 처리 전 무처리에 비해 가장 높은 수치였지만, 115 DAT에는 가장 낮은 수치로 감소된 것을 알 수 있었다. 본 연구를 통해 White 광을 비춘 수목은 전자전달효율 및 건전도가 낮은 것으로 판단되었으며 상대적으로 Warmwhite 광처리구의 스트레스가 더 낮은 것으로 나타났다.
Abstract
In this study, the efficiency of photosynthetic electron transfer according to LED color temperature was verified in order to find a way to efficiently grow trees under night illumination. The experiment was carried out with White treatment, Warmwhite treatment, and non-treatment with donarium cherry. The study uses to a method for analyzing and evaluating the color temperature of an LED light source by photochemical analysis. We found that all treatments 115 DAT of maximum fluorescence amount (P) had the lowest. In the treatment using white light and the Warmwhite light, the T amount of florescence of the late stage during the transition of the J-I level was increased, and the photosystem I electron transfer efficiency was decreased. Therefore, the electron transport efficiency of RE1O/CS and RE1o/RC were reduced. Especially, compared to Warmwhite, the light intensity increased greatly in the white-light treatment, The PITOTALABS of 7 DAT was the highest value, but it was decreased to the lowest value on 115 DAT. This study has shown that the white treatment was low in electron transfer efficiency and soundness. Warmwhite-light treatments showed lower stress.
