restricted (+ tin) tillering wheat near -isolines

A functional-structural plant model of wheat architecture was parameterisedto simulatea pairoflines varying for a tillerinhibition ( tin) gene.Effects of planting configuration were exploredthroughred : far -red (R:FR)signalling onproduction,finalspike numbers, and light interception .Both increasedplant density(125 to200 plants/m 2 )and row spacing(20 to 30 cm)reduced the simulated tillerandspike numbers per plant in bothlines. This reduction was greater in the free -tillering( �tin)than inthe reduced-tillering (+tin)line.At wider row spacing of 30 cm , simulated radiation interception was less in the +tinline than in
