Controls of seedling recruitment of annual species in temperate perennial pastures
Temperate pastures are characterized by low growth rates during the winter.The incorporation of annual species in the mixture gives the opportunity to balance the distribution of the forage allowance through the year.However, successfully seedling recruitment every year depends upon the environmental conditions which : (1 ) allows the reproduction of the mother plant at the end of the growing season (Forcella,2000) and (2) breaks the dormancy of the seeds (Benech et al.,2000).The objective of this work was to evaluate the patterns of seedling recruitment of two annual species, brome grass ( Bromus catharticus) and red clover ( Trifolium pratense), under different environmental conditions.
