[Effect of ice crust on winter wheat overwintering]
1992
Kozlov, G.I.
Data on experimental material as to the effect of ice crust, differing in thickness and length, on resistance to winter wheat overwintering are adduced. Ice crust 1 cm thick was found to have no essential effect on winter wheat plants under any duration of its effect. Ice crust 5 cm thick results in killing 20-40% of winter wheat plants even when its effect is 30 days. Most negative effect on productivity components has ice crust 30 cm thick for the period 60 days and the crust 5 cm thick even after the period 30 day long.
