veris. The long-styled plants tend to flower before the
short-styled. When both forms were legitimately fertilised, the capsules from
the short-styled plants contained, on an average, more seeds than those from the
long-styled, in the ratio of 12.2 to 9.3 by weight, that is, as 100 to 78. In
Table 1.10 we have the results of two sets of experiments tried at different
periods.
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.
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.
