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

After
a time the pots were plunged into the open ground. The same number of
plants of crossed and self-fertilised parentage were measured up to the
summits of their flower-stems, with the result given in Table 4/35.
Those which did not produce flower-stems were not measured.
TABLE 4/35. Reseda lutea, in pots.
Heights of plants to the summits of the flower-stems measured in inches.
Column 1: Number (Name) of Pot.
Column 2: Crossed Plants.
Column 3: Self-fertilised Plants.
Pot 1 : 21 : 12 7/8.
Pot 1 : 14 2/8 : 16.
Pot 1 : 19 1/8 : 11 7/8.
Pot 1 : 7 : 15 2/8.
Pot 1 : 15 1/8 : 19 1/8.
Pot 2 : 20 4/8 : 12 4/8.
Pot 2 : 17 3/8 : 16 2/8.
Pot 2 : 23 7/8 : 16 2/8.
Pot 2 : 17 1/8 : 13 3/8.

Pot 5 : 22 : 16.
Pot 5 : 8 6/8 : 14 3/8.
Pot 5 : 14 2/8 : 14 2/8.
Total : 412.25 : 350.86.
The average height of the twenty-four crossed plants is here 17.17
inches, and that of the same number of self-fertilised plants 14.61; or
as 100 to 85. Of the crossed plants all but five flowered, whilst
several of the self-fertilised did not do so.
