Connection of frost tolerance and alkaloid accumulation potential in poppy (Papaver somniferum L.)
Journal of Applied Botany and Food Quality, 2012 In the Central-European region, a growing interest for winter poppy varieties both for industrial and culinary purposes can be observed. In connection with breeding, we studied if winter hardiness and alkaloid accumulation capacity are linked in some way.
