(in Russian, podpora), a slender pole, 3 to 6 m long, having tines or splits at the upper end and made of hardwood (oak, beech, hornbean, ash). Props are placed under the branches of fruit trees at harvest time to prevent the branches from breaking and bending and to prevent the shedding of fruits during winds. The vertical installment of props and the umbrella-like attachment of branches to props are common.
