Abstract:
Inflorescence and shoot injury to eleven blueberry cultivars growing in central and eastern Iowa was evaluated following unseasonably low temperatures on November 11,1986. In central Iowa, where a low of -20°C was recorded, floret survival varied among cultivars. More than 95% of florets of Jersey,' 'Northblue,' and 'Northsky' survived while less than 65% survived for 'Collins.' No differences in shoot injury were observed among cultivars.
