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


Column 1: Number (Name) of Pot.
Column 2: Crossed Plants.
Column 3: Self-fertilised Plants.
Pot 1 : 40 4/8 : 33.
Pot 1 : 35 : 24.
Pot 1 : 25 : 23.
Pot 2 : 33 4/8 : 30 4/8.
Total : 134.0 : 110.5.
The average height of the four crossed plants is 33.5, and that of the
four self-fertilised plants 27.62 inches, or as 100 to 82. The crossed
plants altogether produced 105 and the self-fertilised plants 63
capsules; or as 100 to 60. In both pots a self-fertilised plant flowered
before any one of the crossed plants.
16. LOASACEAE.--Bartonia aurea.
Some flowers were crossed and self-fertilised in the usual manner during
two seasons; but as I reared on the first occasion only two pairs, the
results are given together. On both occasions the crossed capsules
contained slightly more seeds than the self-fertilised. During the first
year, when the plants were about 7 inches in height, the self-fertilised
were the tallest, and in the second year the crossed were the tallest.
When the two lots were in full flower they were measured, as in Table
5/63.
