Other claims from this paper (9)
- Association Barley produced about 40% more aboveground biomass than wheat by the two-leaf stage.
- Association Barley had two times greater leaf area than wheat by the two-leaf stage.
- Association Barley had a 17% faster average leaf appearance rate than wheat.
- Association Barley had a 35% faster average tiller appearance rate than wheat.
- Observation Relative growth rates for biomass and leaf area were similar in barley and wheat.
- Association Net assimilation rate was 25% greater in wheat than in barley.
- Observation Leaf area ratio was 23% higher in barley.
- Mechanism Variation in specific leaf area was largely responsible for the variation in NAR and LAR.
- Mechanism Factors between germination and the appearance of the second main stem leaf are likely responsible for the greater early vigor of barley.
