Competition Between Ladino Clover Seedlings and Established Orchardgrass in Nutrient Solution Cultures1

Abstract

Abstract

Ladino clover seedlings were grown alone and in association with established orchardgrass in nutrient solution cultures in the greenhouse. Techniques were devised to control competition for light. Nutrient solutions at each of two concentrations were (1) changed frequently and (2) not changed during the experiment. Where solutions were not changed, pH values were controlled and nutrients replenished.

There was no evidence that actively growing roots of well-established orchardgrass released substances in the nutrient solution that affected the yield of ladino clover seedlings.
