THE GROWTH AND NUTRIENT CONTENT OF FESTUCA VIVIPARA (L.) SM. PLANTLETS
SUMMARY The nutrient content of Festuca vivipara (L.) Sm. plantlets from a site in the English Lake District were compared with that of seeds of the closely related species, F. ovina L. The almost linear increase in dry weight of plantlets throughout the growing season was associated with an increas...
