The McIntosh, McIntosh Red, or colloquially the Mac ( - the same as Macintosh) is an apple cultivar. The fruit has red and green skin, a tart flavour, and tender white flesh, which ripens in late September. In the 20th century it was the most popular cultivar in Eastern Canada and New England, and is considered an all-purpose apple, suitable both for cooking and eating raw. Apple Inc. employee Jef Raskin named the Macintosh line of personal computers after the fruit. John McIntosh discovered the original McIntosh sapling on his Dundela farm in Upper Canada in 1811. He and his wife bred it, and the family started grafting the tree and selling the fruit in 1835. In 1870, it entered commercial production, and became common in northeastern North America after 1900. While still important in production, the fruit's popularity fell in the early 21st century in the face of competition from varieties such as the Gala. According to the US Apple Association website it is one of the fifteen most popular apple cultivars in the United States.〔(Apple varieties ) by US Apple Association〕 ==Description== The McIntosh or McIntosh Red (nicknamed the "Mac"), is the most popular apple cultivar in eastern Canada and the northeastern United States. It also sells well in eastern Europe. A spreading tree that is moderately vigorous, the McIntosh bears annually or in alternate years. The tree is hardy to at least USDA Hardiness zone 4a, or . 50% or more of its flowers die at or below. The McIntosh apple is a small- to medium-sized round fruit with a short stem. It has a red and green skin that is thick, tender, and easy to peel. Its white flesh is sometime tinged with green or pink and is juicy, tender, and firm, soon becoming soft. The flesh is easily bruised. The fruit is considered "all-purpose", suitable both for eating raw and for cooking. It is used primarily for dessert, and requires less time to cook than most cultivars. It is usually blended when used for juice. The fruit grows best in cool areas where nights are cold and autumn days are clear; otherwise, it suffers from poor colour and soft flesh, and tends to fall from the tree before harvest. It stores for two to three months in air, but is prone to scald, flesh softening, chilling sensitivity, and coprinus rot. It can become mealy when stored at temperatures below . The fruit is optimally stored in a controlled atmosphere in which temperatures are between , and air content is 1.5–4.5% oxygen and 1–5% carbon dioxide; under such conditions, the McIntosh will keep for five to eight months. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「McIntosh (apple)」の詳細全文を読む スポンサード リンク
