The relations of color to germination and other characters of red, alsike, and white clover seeds
1940
Smith, D.C.
1. Five lots each of red, alsike, and white clover seed were separated individually into four color classes and data obtained on average seed weight, percentage in the sample, germination on blotters and in soil, and hard seeds. 2. Purple and yellowish purple seeds averaged higher in weight than other colors in red clover. Darker-colored seeds were also heavier in alsike and white clovers. 3. Intermediate seed colors were generally most numerous in all clovers studied. Dark colors were frequent in alsike and less so in red and white clovers. 4. In total germination of red clover on blotters, yellow or yellowish seeds were superior. Total germination favored darker colors in alsike clover and yellow in white clover. 5. Hard seeds were most frequent in purple and purplish groups in red clover, in green and blackish-green in alsike clover, and in red and yellowish-red in white clover. 6. Germination in soil was highest in the darker colors in alsike clover and yellow was superior in white clover. Color differences in soil germination of red clover were very slight. 7. Average number of seeds per pound calculated for the samples studied were red clover, 293,600; alsike clover, 677,000; and white clover, 836,100.
