Seeds of both kinds were sown rather thickly on opposite sides of three
pots. When the seedlings were about 3 inches in height, the crossed
showed a slight advantage over the self-fertilised. When two-thirds
grown, the two tallest plants on each side of each pot were measured;
the crossed averaged 16.37 inches, and the self-fertilised 11.75 in
height; or as 100 to 71. When the plants were fully grown and had done
flowering, the two tallest plants on each side were again measured, with
the results shown in Table 3/27.
TABLE 3/27. Salvia coccinea.
Heights of Plants measured in inches.
Column 1: Number (Name) of Pot.
Column 2: Crossed Plants.
Column 3: Self-fertilised Plants.
Pot 1 : 32 6/8 : 25.
Pot 1 : 20 : 18 6/8.
Pot 2 : 32 3/8 : 20 6/8.
Pot 2 : 24 4/8 : 19 4/8.
Pot 3 : 29 4/8 : 25.
Pot 3 : 28 : 18.
Total : 167.13 : 127.00.
It may be here seen that each of the six tallest crossed plants exceeds
in height its self-fertilised opponent; the former averaged 27.85
inches, whilst the six tallest self-fertilised plants averaged 21.16
inches; or as 100 to 76. In all three pots the first plant which
flowered was a crossed one. All the crossed plants together produced 409
flowers, whilst all the self-fertilised together produced only 232
flowers; or as 100 to 57. So that the crossed plants in this respect
were far more productive than the self-fertilised.
