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

Table 2

Number of grains per unit area (NG m⁻²) (grain number from tillers and main shoots), individual grain weight (IGW), number of grain per spike (NGS), and number of grains per spikelet (NGSP) for two triticale cultivars (L4 and L7) and one of wheat (W) in five source-sink manipulation treatments. Data correspond to three experimental cycles.
