Braeburn during commercial long term storage, and it’s usually not possible to tell if an apple has the Braeburn browning disorder until a person bites or cuts into it. Apples respond dramatically to both temperature and atmosphere modification. Rapid temperature reduction and the exacting maintenance of low temperature close to the chilling point of the variety can provide good to medium quality product following 3 to 6 mo of storage and in some cases longer. However, modern commercial warehouses couple temperature management with controlled atmosphere (CA) for long-term storage of apples. Braeburn can be stored at 0 °C in air for
Morphism of algebraic varieties Morphism of algebraic varieties In algebraic geometry, a morphism between algebraic varieties is a function between the varieties that is given locally by polynomials. It is also called a regular map. A morphism from an algebraic variety to the affine line is also called a regular function. A regular map whose inverse is also regular is called biregular, and they are isomorphisms in the category of algebraic varieties. Because regular and biregular are very restrictive conditions – there are no non-constant regular functions on projective varieties – the weaker condition of a rational map and birational maps are frequently used
