对亚热带高海拔半干暖多日照生境代表点四川茂县（Ｉ型区），较亚热带低海拔湿热少日照生境代表点四川雕安（Ⅱ型区）的新红星和金冠苹果着红色度高的生态生理效应的研究表明，Ⅰ型区较Ⅱ型区具有较高的海拔度，较多的紫外光和日照时数，较大的日均气温较差，较低的日均气温、≥１５℃积温、日均最高气温、≥２８℃日均气温频率和日均空气相对湿度；致使果实着色期Ⅰ型区较 Ⅱ型区两品种、同一生境下新红星较金冠的果皮花青昔（Ａｎｔ）积累多，从而红色度高。
The representatives of the subtropical high-altitude semi-dry and warm multi-sunlight habitat Maoxian County, Sichuan Province (I type area), the representative of the subtropical low-altitude humid and hot daylight habitat in Sichuan Diao’an (Ⅱ area) Physiological effects showed that Type Ⅰ area had higher altitude, more UV light and sunshine duration than Type Ⅱ area, with larger average daily temperature, lower average daily temperature and ≥15 ℃ accumulated temperature , The highest daily average temperature, the average daily temperature of ≥28 ℃ and the relative humidity of daily average air; resulting in the accumulation of Ant in the typeⅠand type Ⅱ of the fruit in the same habitat compared with that of the Golden Crown in the same habitat More, so red degree is high.
