词汇 bramley-s seedling
词源
Bramley’s seedling. Bramley’s seedling is a delicious English apple, notable not only because it was discovered by a butcher named Bramley of Southwell, Nottinghamshire in his garden, but because it is a “sport,” or mutation. Most mutations, or changes in genes, occur in seedlings, but the Bramley was the result of a bud mutation, a variation in which only part of a plant is affected. Thus the first Bramley as well as the first Gold- en Delicious apple, and the first New Dawn Rose, among others, developed on one branch of a plant bearing an entirely different race. The Boston fern, which originated in a shipment of ferns sent from Philadelphia to Boston in 1894, is another well-known mutation, but the most famous bud sport is the nectarine.
