Summary Trees need to store reserves to allow their survival during winter and for bud flush and leaf growth in the following spring. In many tree species, these reserve functions are mainly covered by starch, which is degraded to soluble carbohydrates during the dormant season for maintenance respiration and in spring during bud flush. We conducted girdling experiments on poplar (Populus deltoides × nigra cv. Dorskamp) in order to elucidate how interrupted transport of carbohydrates to the roots during autumn affects plant survival during winter and bud flush in spring. We measured the content of starch, sucrose, glucose, fructose, raffinose and stachyose in st...
