GENUS
李属(学名:Prunus),又名櫻桃屬、桃屬、梅屬、櫻屬、杏屬,是薔薇科的一个属。包括李、樱桃、桃、杏和扁桃。传统上被放在蔷薇科作为一个亚科,李亚科(或桃亞科),但是有时也归类于另外一科,李科(或桃科、櫻科)之內。樱桃属内植物有数百种类分布在地球的北温带地区。 植株為乔木或灌木。花通常呈白或粉红色,包含五瓣花瓣和五个萼片。花為單生花、繖形花序或總狀花序。果實為核果,內有一個由石細胞組成的硬核。葉為單葉,通常為披針形,葉緣有鋸齒。 曬乾的李稱為嘉慶子[1]。 目录 1 分类 2 用途 3 物种 3.1 东半球 3.2 北美 4 参见 5 外部链接 6 參考 分类 历史的处理将樱桃属分成几个不同的属,但这种分离现在不广为承认,而只是同一属下的亚属。北美的ITIS(综合分类信息系统)只承认一个属。右表列出本属内的各物种。 李属 桃亚属(Amygdalus):包括桃、扁桃等,花三朵同生,贴梗,春季出叶前开花,果实侧面有一道沟,果核表面有沟槽,模式种是扁桃(Prunus dulcis)。 李亚属(Prunus):包括李子和杏等,花单生,春季出叶前开花,果实侧面有一道沟,果核光滑。模式种是欧洲李(Prunus domestica)。 酸樱桃亚属(Cerasus):包括樱桃等:花单生,春季出叶前开花,花为伞状花序,花梗长,果实光滑,沟不明顯,果核光滑。模式种是酸樱桃(Prunus cerasus)。 樱桃亚属(Lithocerasus):包括普通樱桃和櫻花:花三朵同生,春季出叶后开花,花为伞状花序,花梗长,果实光滑,沟不明顯,果核光滑。模式种是矮樱桃(Prunus pumila)。 稠李亚属(Padus):包括稠李,花单生,晚春出叶后开花,花为伞状花序,花梗短,果实光滑,沟不明顯,果核光滑。模式种是欧洲稠李(Prunus padus)。 桂樱亚属(Laurocerasus):包括桂樱,花单生,春季出叶前开花,总状花序,果果实光滑,沟不明顯,果核光滑。大部分种是长青树, 模式种是桂樱(Prunus laurocerasus)(其他亚属都是落叶的)。 用途 樱桃属包括扁桃、杏、樱桃、桃和李,这五种都有为商品化果实生产而发展的栽培品种。扁桃的可食部分是种子;扁桃果实是核果而不是真坚果。也有一些物种、杂交品种和栽培品种被严格地培植做为装饰性植物,通常是因为它们的开花量丰富,有时候也为树叶和树皮。这些装饰类品种包含被统称作“观赏类樱桃”的那些。 因为它们作为食品和装饰物,有着相当可观的价值,许多樱桃属物种已经被传播引进到不是其本土物种的一些地区。许多原始品种被栽种作为装饰或果品,已经在世界各处种植,而且一些品种已经在它们的本土之外的地域变得自然化了。 樱桃属物种还是包括青尺蛾(Light Emerald)及蠹蛾(Buff-tip)在内的一些鳞翅类物种 (Lepidoptera)的食

Many members of the genus are widely cultivated for their sweet, fleshy fruit and for decorative purposes of their flowers. Prunus fruit are drupes, or stone fruits. The fleshy mesocarp surrounding the endocarp is edible while the endocarp itself forms a hard, inedible shell called the pyrena ("stone" or "pit"). This shell encloses the seed (or "kernel"), which is edible in some species (such as sweet almonds), but poisonous in many others (such as apricot kernels). Besides being eaten off the hand, most Prunus fruit are also commonly used in processing, such as jam production, canning, drying, and the seeds for roasting.
