This project addresses the effects of climate change in the UK on blackcurrant production, where the trend towards warmer winters has adversely affected dormancy break and subsequent crop yields and quality, substantially reducing profitability. The use of existing dormancy-breaking treatments, developed for stone fruit crops, will be assessed for their efficacy in blackcurrant, their use optimised, and their mode of action evaluated at a physiological/biochemical level. From this, a new improved product for blackcurrant and 'best practice' guidelines for growers can be developed. Additionally, models predicting responses to the chilling environment for different varieties will be established, and this information will be used to direct the use of dormancy-breaking treatments to improve yield and quality. The project outcomes will directly influence future blackcurrant production in the UK, and will also be applicable to other perennial fruit crops, many of which have high chill requirements and are most productive after cold winters.

该项目解决了英国气候变化对黑醋栗生产的影响，暖冬的趋势对休眠的打破以及随后的作物产量和质量产生了不利影响，大大降低了盈利能力。将评估为核果作物开发的现有休眠打破处理方法在黑加仑中的功效，优化其使用，并在生理/生化水平上评估其作用模式。由此，可以开发一种新的黑醋栗改良产品和种植者的“最佳实践”指南。此外，还将建立不同品种对低温环境反应的预测模型，这些信息将用于指导打破休眠处理的使用，以提高产量和品质。该项目的成果将直接影响英国未来的黑醋栗产量，也将适用于其他多年生水果作物，其中许多作物对寒冷的要求很高，在寒冷的冬天之后产量最高。
