Description
Strains of Trifalium brachycalycinumm (B) and Trifolium subterraneum • (S) were evaluated for burr burial ability and capacity to set seed when ' burial was artificially prevented. In one experiment S buried a higher • number of burrs and more deeply in the soil relative to B. There was evidel)ce that unburied burrs were undeveloped in S while a higl\ proportion of them developed in. B. In a second experiment prevention of burial drastically reduced seed yield in both species but the reduction was higher in S. Effects on yield components were. also differen.1 in the 2 species, Seeds/burr declined only in B while number of burrs declined only in S, Seed weight was markedly reduced in both species with a greater effect in S. Significant interactions lines x. treatments. for both seed yield . and yield components suggests the possibility of selecting strains able to produce adequate seed when burial is prevented.
