N=29). It can be the consequence of trees adapting to the changed water regime. That is why LWCI index is larger close to ditches and less in the middle of strip between the ditches. NDVI is qualitatively connected with the volume of spruce, fir and Siberian cedar and with the density of natural reforestation. That indicates to perspective of use of this vegetation index for estimation of fore ...

The dynamics data (1995-2010 years) of composition and productivity of complex-mixed stands are offered. The data were obtained due to regular control at the three permanent sample sites, located in the central zone of the floodplain of the Bolshaya Kokshaga. Dependance between current trees increment and their original size were estimated. Tendencies for trees mortality were revealed.It was d ...

Ultraviolet exposure (wavelength of 315…380 nm ) on seeds is based on the ability to stimu-late photochemical processes in an irradiated biological object, activating phenolic metabolism in the cells. Positive effect of this method on plants and seeds before sowing has long been known. Nowadays with the advent of new technologies it has a great practical perspective. At the same time, it is ne ...

One of the main ways to increase efficiency of harvesting machines is to provide the tractors designed to run in specific operating conditions. The main factors affecting the performance in specific environmental and production conditions are manoeuvrability of tractor and work capacity of skid trails. In the course of development of harvest sites with low bearing capacity, necessity of stump- ...
