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


Ipomoea purpurea--seeds per capsule on crossed and self-fertilised
plants from the same parents as in the last case, but growing much
crowded, spontaneously self-fertilised under a net, in number: 93.
Ipomoea purpurea--productiveness of the same plants, as judged by the
number of capsules produced, and average number of seeds per capsule:
45.
Ipomoea purpurea--third generation: seeds per capsule on crossed and
self-fertilised plants, spontaneously self-fertilised under a net, in
number: 94.
Ipomoea purpurea--productiveness of the same plants, as judged by the
number of capsules produced, and the average number of seeds per
capsule: 35.
Ipomoea purpurea--fifth generation: seeds per capsule on crossed and
self-fertilised plants, left uncovered in the hothouse, and
spontaneously fertilised: 89.
Ipomoea purpurea--ninth generation: number of capsules on crossed plants
to those on self-fertilised plants, spontaneously self-fertilised under
a net: 26.
Mimulus luteus--an equal number of capsules on plants descended from
self-fertilised plants of the 8th generation crossed by a fresh stock,
and on plants of the 9th self-fertilised generation, both sets having
been left uncovered and spontaneously fertilised, contained seeds, by
weight: 30.
Mimulus luteus--productiveness of the same plants, as judged by the
number of capsules produced, and the average weight of seeds per
capsule: 3.
