spruce undergrowth

Dynamics of pigment fund formation and spruce growth in birch blueberry forest in tree stand ontogeny

The study of growth peculiarities and accumulation dynamics of photosynthetic pigments in spruce undergrowth in birch blueberry forests of different age is made. Methodology is described as well as brief characteristics of experimental objects are given.

Spruce undergrowth biomass structure in birch forests of various ages

In birch forests of bilberry type in vegetation conditions the influence of age statement of leaf-canopy on biometrical parameters of spruce undergrowth under the Syamzhenskiy district of the Vologda region is studied. It is established that with the birch age increase the conditions for growth and development of conifer undergrowth deteriorate, as a result it changes the biomass structure, morphometrical parameters and age of under canopy needles.
