| Abstract: | In order to explore the distribution of non structural carbohydrates in Pinus sylvestris var.mongolica,pure forest and mixed forest in Northwestern Liaoning Province were selected as the research objects,and the concentrations of soluble sugar,starch and TNC in leaves,branches and roots of Pinus sylvestris var.mongolica in growing season were compared.Results shows that Pinus sylvestris var.mongolica in pure forest have higher soluble sugar and TNC content than Pinus sylvestris var.mongolica in mixed forest.The starch content of Pinus sylvestris var.mongolica is maintained at a relatively high level;the soluble sugar,starch&TNC content in the branches and leaves of each forest are significantly higher than that of the root system(P<0.05).Compared with pure forest,Pinus sylvestris var.mongolica in mixed forest is more conducive to energy conduction,and it is conducive to the accumulation of non-structural carbohydrates in pure forest. |
