Germination of Cultivars of Trifolium subterraneum L. in Relation to Matric Potential1
- James A. Young2,

The germination of 11 cultivars of subclover (Trifolium subterraneum L.) in relation to matric potential was dependent on the texture of the soil substrate. Germination terminated or was virtually zero at minus 6, 8, and 12 bars, respectively, on sand, loam, and clay substrates. Germination on soil beds in the greenhouse was dependent on substrate texture and the amount of seed coverage. On sand beds where the matric potential was high, hydraulic conductivity between the sand grains and the seeds on the soil surface was apparently so low as to impede germination. In all tests in which germination was more than minimal, variability among the cultivars was marked.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
