Development of methods for preparing lignified cuttings of tall blueberry for rooting

Abstract

When propagating tall blueberries by lignified cuttings, the optimal type of substrate and the method of preparing cuttings for rooting have been established. It has been experimentally proven that lignified cuttings before planting for rooting are effectively furrowed (wounding in the lower part of the cuttings along the shoot axis), treated with Ukorzeniacz Baqua growth powder (0.2%) and rooted in a substrate consisting of high peat. At the same time, the rooting rate of the Bluecrop variety was 69% versus 47% in the control rooted on high-moor peat and against 37% in the control rooted on a mixture of high-moor peat with perlite. And in the Northland variety-79% versus 59% in the control rooted on high-moor peat and against 52% in the control rooted on a mixture of high-moor peat with perlite (1:1).
