High temperature is one of the important environmental factors limiting cultivation of apple (Malus domestica Borkh). The expression of genes related with anthocyanin synthesis and sugar accumulation in response to high temperature was studied in the 'Hongro' apple fruits at different developmental ...

사과란? | 사과(Malus domestica Borkh.)는 전세계적에서 생산되는 온대과수 중 하나로 우리나라에서 생산량은 두 번째이며 재배면적이 가장 넓은 과수로, 사과 품종 재배면적은 ‘후지’(70.1%), ‘홍로’(14. | |
도시화와 산업화로 인한 온도 상승이 사과 과실에 미친 부정적 영향은? | 최근 도시화와 산업화로 인한 온도 상승은 사과 과실의 성장 지연, 당함량 감소, 착색과 형태 불량, 과실의 저장수명 단축 등으로 고품질의 사과 생산과 농가 수익에 부정적인 영향을 끼친다(Hulme 등, 1994). 기후 변화와 지구온난화에 의한 지속적인 고온은 과실 생장에 부정적인 영향을 미치고, 생리장해의 한 종류인 밀증상도 생육기의 저온보다는 고온에서 발생률 및 발생 정도가 심한 것으로 보고되어 있다(Park 등, 2009). | |
사과 과실의 품질을 결정하는 중요한 요소는 무엇인가? | 사과는 내외부의 스트레스로 인해 생산성이 감소하거나 품질의 저하 등의 부정적인 영향을 받는다. 사과에서 과피색과 가용성 고형물 함량은 과실품질을 결정하는 중요한 요소이며, 동일한 장소에서 오랜 기간 생육하므로 기후 또는 미기상 조건의 영향을 크게 받는다(Seo와 Park, 2003). 과실의 품질은 생장시 기에의 광합성활동에 의해 결정되고 온도 조건의 영향을 받는다(Saure, 1990; Song 등, 2003; Tomana와 Yamada, 1988a). |
