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

新鲜农产品极易腐烂，从生产者到零售商都可能发生严重的浪费。2013年，英国种植了超过3000公顷的新鲜防风草，生产了82500吨防风草，市场价值为3100万英镑（Defra），防风草种子的价值估计约为400万英镑。在欧洲防风草中，种植者面临的一个主要问题是根部被拔起时皮肤被擦伤，导致作物被超市拒收，损失惨重。不幸的是，瘀伤在包装时并不总是很明显，并且可能在24小时后发展。有许多因素可以增加瘀伤的发生。与Elsoms合作，该项目旨在了解导致瘀伤发生率的农艺因素，目前这方面的信息很少，为农学家提供证据基础，为种植者提供支持生产的建议，并减少从农场到零售商的行业浪费。该项目还旨在确定有助于抗擦伤的生物和遗传性状，这将有助于育种者生产抗擦伤的品种，从而有助于提高生产力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.
