A changing winter climate has a major impact on blackcurrants

Gillian A. Fraser
The blackcurrant is an economically important crop in the UK.
Awareness to its excellent source of antioxidants, phenolics,
flavanoids, anthocyanins, Vitamin A and Vitamin C is growing. Over the
past years, however, blackcurrant growers have been reporting that bud
burst is occurring later than expected and buds are bursting less
evenly. Crop quality for some cultivars has been reduced due to the
increased ratio of unripe to ripe berries as a result of uneven flower
emergence. Such observations may be as a result of the crop receiving
insufficient winter chilling. To address this, The University of
Reading and GlaxoSmithKline (Blackcurrant Growers Research Development
Fund) came together in partnership in 2001, by supporting a 3year PhD
project (Gillian A. Fraser) at The University of Reading (Figure 1).
The project examines the effects of winter chilling on blackcurrant (Ribes
nigrum L.). It aims to develop chill unit models to quantify the
optimum chilling temperature and duration for three commercial
blackcurrant cultivars. Further, it investigates the effect of
management techniques on the following year’s bud burst behavior.
As a temperate zone crop the blackcurrant requires a period of low
temperature to break winter dormancy and ensure rapid and even bud
burst the following spring. If the plants do not receive sufficient
chilling, delayed and uneven bud break (Figure 2) has a detrimental
effect on flower emergence and the resultant crop yield and quality
are significantly reduced.
Climate change may be a serious threat to the UK blackcurrant
industry. The United Kingdom Climate Impacts Programme 2002 (UKCIP02)
has predicted that, by 2080, the average UK temperature will have
increased by between 1C and 5C, depending on the scenario. This work
will aid in overcoming a lack of winter chilling. Our chill unit
models will enable growers to monitor the chilling their cultivars
have received and to manage the crop accordingly, i.e. by application
of dormancy braking substances to force even bud burst.
