Darwin, Charles, 1809-1882

"Effects of Cross and Self Fertilisation in the Vegetable Kingdom"


Some long-styled and short-styled plants were now raised from purchased
seeds, and flowers on both forms were legitimately crossed with pollen
from a distinct plant; and other flowers on both forms were
illegitimately fertilised with pollen from the flowers on the same
plant. The seeds were sown on opposite sides of Pots 1 to 4 in Table
6/95; a single plant being left on each side. Several flowers on the
illegitimate long-styled and short-styled plants described in the last
paragraph, were also legitimately and illegitimately fertilised in the
manner just described, and their seeds were sown in Pots 5 to 8 in the
same table. As the two sets of seedlings did not differ in any essential
manner, their measurements are given in a single table. I should add
that the legitimate unions in both cases yielded, as might have been
expected, many more seeds than the illegitimate unions. The seedlings
whilst half-grown presented no difference in height on the two sides of
the several pots. When fully grown they were measured to the tips of
their longest leaves, and the result is given in Table 6/95.
TABLE 6/95. Primula sinensis.
Heights of plants measured in inches.
Column 1: Number (Name) of Pot.
Column 2: Plants from legitimately Crossed seeds.
Column 3: Plants from illegitimately Self-fertilised seeds.
Pot 1 : 8 2/8 : 8.
From short-styled mother.
Pot 2 : 7 4/8 : 8 5/8.
