METHOD FOR DETERMINING TERMINATION OF PERENNIAL FORAGE GRASS WINTERING

摘要

FIELD: agriculture. SUBSTANCE: method involves selecting perennial and productive forms under field conditions in autumn-winter period, when temperature is changed from -3 C to -5 C; transplanting plants into hothouse and growing while providing continuous illumination; selecting plants with terminated wintering stage by growth cone meristem resumption with transfer to flowering phase and plant with unterminated wintering stage by retained vegetative phase. EFFECT: simplified determination of terminated wintering stage and increased efficiency. 1 tbl, 2 ex
