REGENERATIVE PROPERTIES OF GRAPE CUTTINGS UNDER THE INFLUENCE OF TREATMENT WITH IAA
06.00.00 Agricultural sciences
DescriptionThe article presents the research results of eight grapes rhizogenesis of different genetic origin of the cuttings after treatment with 0.01% solution of IAA for 24 h. It was found, that the activity of regenerative processes in grape cuttings depends on the varietal characteristics, storage conditions and the activation of IAA. It leads to disruption of existing natural correlations, including suppressing the longitudinal polarity. Root-growing ability of cuttings is a genetically determined feature: the effect of IAA did not cause the stability of the positive reaction; it is determined by genotype and depends on the quality and physiological condition of the cuttings

JUSTIFICATION OF SPAR ROADS JUNCTION ANGLES TO THE FOREST ROADS
DescriptionThe zone of attraction of hauling branches in an allocation scheme based on the roads in "herringbone" forest resources is divided into 'near' and 'distant' parts with respect to location of contiguity point to forest road. In the "distant" part at certain parameters of cutting area, it is advisable to lay spar roads to a branch at an angle equal to the optimal angle of junction of branch to line, which reduces the cost of removal of wood on the branch. In the "near" part, as well as in forked and combined schemes of road allocation in forest resources , spar roads should be run under the best angles determined by established analytical relationship to reduce the cost of removal of wood
