For belowground biomass, the family effect was close to significance at the 0.05 level ( p = .078).
For belowground biomass, the family effect was close to significance at the 0.05 level ( p = .078).
The magnitude of quantitative genetic variation for all traits differed across treatments: Genetic variance of biomass was 0 in the warmest treatment, while highly significant diversity was found in average conditions, resulting in broad‐sense heritability of 0.31.
