Pawpaw (Asimina triloba) is a unique tree fruit native to the Eastern and Mid-Western US and the Carolinian Forests of Southern Ontario. It is highly aromatic, has a sweet, almost tropical-like mango-banana flavour, and is the largest native fruit in North America. Although it is a hardy (to USDA Zone 5) indigenous Canadian fruit, it is almost unknown to Canadian consumers, and indeed anywhere else. The principal reason for this lack of acceptance in the commercial market is that certain genetic and domestication traits make it unattractive. In descending order, these limitations are: 1) a short shelf life, in that Canadian and US pawpaws become over-mature within 4 - 5 days unless refrigerated, 2) an abundance of big black inedible seeds, that limit its attractiveness and makes for messy eating and handling, 3) a low yield which usually requires

Pawpaw（Asimina triloba）是一种独特的果树，原产于美国东部和中西部以及安大略南部的哥伦比亚森林。它非常芳香，有一种甜的，几乎像热带芒果香蕉的味道，是北美最大的本土水果。虽然它是一种哈代（美国农业部第5区）加拿大本土水果，但加拿大消费者几乎不知道它，甚至在其他任何地方也不知道。在商业市场上缺乏接受的主要原因是某些遗传和驯化特征使其缺乏吸引力。按降序排列，这些限制是：1）保质期短，因为加拿大和美国的木瓜在4 - 5天内就会过度成熟，除非冷藏，2）大量的大的黑色不可食用的种子，这限制了它的吸引力，并使食用和处理变得混乱，3）产量低，通常需要
