Plants of everbearing strawberry (Fragaria x ananassa Duch. ‘Quinault’) were grown in solution culture with 0.01, 0.05, 0.25, and 1.25 ppm boron. Fruit developed abnormally on deficient plants, but there was no reduction in fruit weight. Where boron was insufficient, flower number per leaf, fruit set, or fruit enlargement limited yield but where boron was intermediate, leaf numbers limited yield. No single component limited yield at the highest level of boron.
