Distribution of radioactive products of photosynthesis in Scots pine (Pinus sihestris L.) seedlings during the first vegetation season

Abstract


Dynamics of translocation and distribution of radioactive photosynthetic products in one year old pine (P. silvestris L.) seedlings was investigated at different growth stages. It was found that the utilization of photosynthetic products in particular organs depends greatly on the growth stage. Loses of photosynthetic products as a result of respiration were the smallest at the stage of intensive needle growth and the greatest at the stage of approaching dormancy.
