Lassen sich Winterweizensorten hinsichtlich ihres Beschattungsvermögens statistisch gesichert in Landessortenversuchen voneinander unterscheiden?

Summary

DeThe effect of winter wheat varieties on shading capability was examined in cultivar trials. From 2010 to 2012 field trails with 16 to 22 different varieties of winter wheat were carried out on 13 to 14 different sites in Germany. The light transmission was measured at 2 (2010) or 3 (2011, 2012) development stages of winter wheat 2 cm above soil surface in the stands. It was shown that there have been substantial differences in light transmission between winter wheat varieties in organic farming especially during early growing (tillering of wheat).
