TABLE 1.10. Primula Sinensis.
Column 1: Nature of the Union. Column 2: Number of Flowers fertilised. Column 3: Number of good Capsules produced. Column 4: Average Weight of Seeds per Capsule. ... Column 5: Average Number of Seeds per Capsule as ascertained on a subsequent occasion.
Long-styled by pollen of short-styled. Legitimate union : 24 : 16 : 0.58 :: 50.
Long-styled by own-form pollen. Illegitimate union : 20 : 13 : 0.45 :: 35.
Short-styled by pollen of long-styled. Legitimate union:
8 : 8 : 0.76 :: 64.
Short-styled by own-form pollen. Illegitimate union :
7 : 4 : 0.23 :: 25.
A SUMMARY:
The two legitimate unions together : 32 : 24 : 0.64 :: 57.
The two illegitimate unions together : 27 : 17 : 0.40 :: 30.
The fertility, therefore, of the two legitimate unions together to that of the two illegitimate unions, as judged by the proportional number of flowers which yielded capsules, is as 100 to 84. Judging by the average weight of seeds per capsule produced by the two kinds of unions, the ratio is as 100 to 63. On another occasion a large number of flowers of both forms were fertilised in the same manner, but no account of their number was kept. The seeds, however, were carefully counted, and the averages are shown in the right hand column. The ratio for the number of seeds produced by the two legitimate compared with the two illegitimate unions is here 100 to 53, which is probably more accurate than the foregoing one of 100 to 63.
