Germination tests with pollen of stocks



  1. 1.

    Comparative tests have been made of the germination of pollen of stocks on nutritive agar. The mean percentage of germination was 5.5 per cent. for pollen of a double-throwing cream race, and 8.4 per cent. for that of a pure single cream race. The difference is statistically of only doubtful significance. The phenomenon previously considered as nearly 100 per cent. germination in sugar solution is not true germination.

  2. 2.

    Tests have also been made of germination on the stigma. The mean percentage was 16.7 per cent. for the double-throwing cream race and 31.1 per cent. for the pure single cream, the difference being significant. The possible interpretation of these results for the genetics of stocks is considered.
