Relationships among Laboratory Germination, Greenhouse, and Field Emergence of Four Castor Seed Lots1

  1. R. E. Stafford and
  2. R. B. Metzer2



High-, intermediate-, and low-germinating castor seed lots were evaluated for their performance in rolled germination paper, Kinipak, sterile sand, and field soil. High-germinating seed gave similar results on the four substrates. Low- and intermediate-germinating seed lots gave maximum germination in sterile sand and field soil. High positive correlations were found among all germination substrates. Laboratory germination in tetramethylthiuram disulfide (thiram)-treated rolled germination paper at standard temperatures and germination on Kimpak at a constant 27 C were good indicators of seedling emergence in the field.
