Radiation use efficiency of alfalfa‐tall fescue mixtures in a temperate humid area

摘要：

Alfalfa ( Medicago sativ a L.) and tall fescue ( Festuca arundinacea Screb.) have ecotypes with different responses to temperature.Hypothetically,combination of germplasm with different patterns of seasonal growth might exhibit advantages in radiation use efficiency ( RUEfa).In the Humid Pampa region, grass is the main species in these mixtures in winter.However, seasonal transition is crucial to study mechanisms of dry matter accumulation in mixtures with cultivars of different temperature responses.In this work, RUEfa of two alfalfa‐tall fescue mixtures are presented.
