Eschscholtzia californica--productiveness of the same plants, as judged
by the number of capsules produced, and the average number of seeds per
capsule: 40.
Reseda odorata--crossed and self-fertilised plants, left uncovered and
cross-fertilised by bees; produced capsules in number (about): 100.
Viola tricolor--crossed and self-fertilised plants, left uncovered and
cross-fertilised by bees, produced capsules in number: 10.
Delphinium consolida--crossed and self-fertilised plants, left uncovered
in the greenhouse, produced capsules in number: 56.
Viscaria oculata--crossed and self-fertilised plants, left uncovered in
the greenhouse, produced capsules in number: 77.
Dianthus caryophyllus--plants spontaneously self-fertilised under a net;
capsules on intercrossed and self-fertilised plants of the 3rd
generation contained seeds in number: 125.
Dianthus caryophyllus--plants left uncovered and cross-fertilised by
insects: offspring from plants self-fertilised for three generations and
then crossed by an intercrossed plant of the same stock, compared with
plants of the 4th self-fertilised generation, produced seeds by weight:
73.
Dianthus caryophyllus--plants left uncovered and cross-fertilised by
insects: offspring from plants self-fertilised for three generations and
then crossed by a fresh stock, compared with plants of the 4th
self-fertilised generation, produced seeds by weight: 33.
