Vegetative growth and frost hardiness of cloudberry ( Rubus chamaemorus) as affected by temperature and photoperiod
The effect of photoperiod and temperature on growth and induction and development of frost hardiness in cloudberry ( Rubus chamaemorus L.) was examined in two experiments. The photoperiods were 8, 12 or 24 h and the temperatures were 18, 15, 12, 9, 4, 3, –3 or –4°C depending on the experiment. The l...
