Intervention effect Higher seeding rates showed self-thinning.
Association Sampling date was the key factor for leaf number.
Association Green leaf number rose as growing degree days accumulated.
Association At low density, main-stem leaf number increased after GS30 until flag leaf emergence.
Association Green leaf number in high-density tillers and low-density winter or early spring tillers leveled off and then declined between GS30 and maturity.
Intervention effect At high seeding rate, only the main stem and occasional tiller reached maturity.
