Changes in Number and Weight of Wheat and Triticale Grains to Manipulation in Source-Sink Relationship

Table 1

Grain yield (GY), above-ground dry matter at physiological maturity (AGDM), and harvest index (HI); genotypes (G), years (Y), and five source-sink manipulation treatments (T) (defoliation (Df), shading (S), degraining (D), thinning (Th), and control (C)). Data correspond to average of each year.
