사과 '쓰가루' 품종의 과실 품질에 영향을 미치는 기후요인

Abstract

An analytical study was conducted in 2002 to observe the relationship betwen meteorological elementsand the fruit quality of Tsugaru apples at 8 orchards. The higher average air temperature in Augustmade a higher content of soluble solids, but showed a lower anthocyanin content. As the average airtemperature from April through August increased, flesh firmnes decreased; and as the maximum airobserved that the cytohistological characteristics of Tsugaru apples were correlated with the average airtemperature during the growing season. As average air temperature during the growing season increased,the epidermal layer of the fruit skin became thinner, starch density in the flesh decreased, intercellularspace was larger, and tissue structure became looser.
