Temperature and time variables for accelerated ageing testing of Leymus chinensis seed

摘要：

Accelerated ageing (AA) is a test widely used to evaluate seed vigor in various species and exposes seeds for short periods to the two environmental variables which cause rapid seed deterioration, high temperature and high relative air humidity (Delouche and Baskin, 1973 ; TeKrony, 1993).Temperature and time regimes for standardized accelerated ageing tests using the inner chamber method have been published for several crop species ( Hampton and TeKrony, 1995 ).Leymus chinensis ( Trin.) Tzvel, a perennial rhizomatous grass, adapts to the cool and semi‐humid climate of the grasslands of China (Gu et al, 2005).Specific AA test parameters for L.chinensis have not been established.
