Sweet cherry resistance to spring frost damage at bloom stage

Original language description

Spring freezes can cause severe economic loss in cherry orchards due to bud, flowers or fruitlets damage in many places in Europe. Spring frost resistance at the bloom stage was evaluated on twenty five sweet cherry cultivars during frost event in the spring 2017. Cherry cultivars were evaluated in two orchards at location Holovousy, Czech Republic. Night temperatures dropped to - 3.1 °C in the first orchard respective - 3.3 °C in the second orchard. Frost resistance was evaluated as % damage of flowers. The most resistant was evaluated cultivar ʻJacintaʼ with 37 % damage followed by cultivar ʻSandra Roseʼ (60 % damage) and ʻEarly Korvikʼ (65 % damage). Six cultivars showed damage between 71 - 80 %, eight cultivars between 81- 90 % and eight cultivars over 90 %. Differences between cultivars showed different level of resistance to spring frost at the full bloom stage.
