Investigation into the agronomic and biological factors affecting postharvest bruising in Pastinaca sativa (Parsnip)

新鲜农产品极易腐烂，从生产商到零售商都可能发生重大浪费。2013年，英国种植了超过3,000公顷的新鲜防风，生产了82,500吨防风，市场价值为3100万GB(Defra)，估计防风种子的价值约为400万GB。在防风中，种植者面临的一个主要问题是，当根部被提起时，皮肤会瘀伤，导致超市以巨大损失拒绝接受作物。不幸的是，淤青在包装点并不总是明显的，并可能在24小时后发展。有许多因素可以增加瘀伤的发生。该项目与Elsoms合作，旨在了解导致擦伤发生率的农学因素，目前信息很少，为农学家提供证据基础，为种植者提供支持生产的建议，并减少从农场门口到零售商的行业浪费。该项目还旨在识别有助于增强抗擦伤能力的生物和遗传特征，这将有助于育种者生产抗擦伤品种，帮助提高生产率并减少供应链上的浪费。

Fresh produce is highly perishable and significant wastage can occur from producer through to retailer. In 2013 over 3,000 hectares of fresh parsnip were grown in the UK producing 82,500 tonnes of parsnip, with a market value of £31M (Defra), with the value of parsnip seed estimated to be approximately £4M. In parsnips a major problem for growers is bruising of the skin when the root is lifted, leading to crops being rejected by the supermarkets at a significant loss. Unfortunately bruising is not always evident at the point of packing and can develop up to 24 hours later. There are a number of factors which can increase the occurrence of bruising. Working with Elsoms this project aims to understand the agronomic factors that contribute to bruising incidence, where currently there is little information, providing agronomists with the evidence base to provide growers with recommendations that support production, and reduce industry wastage from farm gate to retailer. This project also aims to identify the biological and genetic traits that help confer resistance to bruising, this will help breeders produce bruising resistant varieties that help to increase productivity and reduce wastage along the supply chain.
