Effect of increased autumn temperature and CO2 concentration on frost hardening and winter survival in Lolium perenne

摘要：

Introduction Before 2100,the average autumn temperature in Norway is expected to increase by 1.4to 5.9 °C ( RegClim,2005).At the same time,the CO2 concentration will increase.The aim of the present study was to investigate how a temperature increase during autumn will affect frost hardening,winter survival and spring growth of perennial ryegrass ( Lolium perenne L.) on a coastal location in Norway,at the present and a future CO2 level.
