METHOD FOR ASSESSING FROST RESISTANCE OF WINTER WHEAT PLANTS Russian patent published in 1995 - IPC

Abstract RU 2025941 C1

FIELD: agriculture. SUBSTANCE: frost resistance is assessed by preparing aqueous extract from just-germinated seeds which have been held in distilled water for 24 h at 2 C. Then the content of ions NH+4

in aqueous extract is determined per unit weight of dry matter of the seeds weighed after separation of ions NH+4
and the obtained value is used to assess frost resistance of plants. EFFECT: higher efficiency. 1 tbl
