METHOD FOR PRODUCING GRAFTED PLANTING MATERIAL OF LILAC Russian patent published in 2003 - IPC

FIELD: horticulture. SUBSTANCE: method involves grafting of cultured sort with following planting of grafted plants in container comprising substrate by deepening roots of rootstock into substrate for 2/3 of roots total vertical length while leaving 1/3 of root length in the vicinity of root neck on substrate surface; exposing grafted plants together with container to pulsed magnetic field with amplitude value of magnetic induction of 0.05 T for 5 min. Grafted plants are planted in container filled with substrate preliminarily magnetized by exposing it to permanent magnet field of 600 Oe intensity for 72 hours. EFFECT: increased yield of grafted planting material with improved biometric parameters. 3 cl, 1 tbl
