Fifty-six spontaneously self-fertilised capsules on the above five
crossed plants, and twenty-five spontaneously self-fertilised capsules
on the above five self-fertilised plants, yielded seeds in the
proportion of : 100 to 99.
Combining the total number of capsules produced by these plants, and the
average number of seeds in each, the above crossed and self-fertilised
plants yielded seeds in the proportion of : 100 to 64.
Other plants of this first generation grown under unfavourable
conditions and spontaneously self-fertilised, yielded seeds in the
proportion of : 100 to 45.
THIRD GENERATION OF CROSSED AND SELF-FERTILISED PLANTS.
Crossed capsules compared with self-fertilised capsules contained seeds
in the ratio of : 100 to 94.
An equal number of crossed and self-fertilised plants, both
spontaneously self-fertilised, produced capsules in the ratio of : 100
to 38.
And these capsules contained seeds in the ratio of : 100 to 94.
Combining these data, the productiveness of the crossed to the
self-fertilised plants, both spontaneously self-fertilised, was as : 100
to 35.
FOURTH GENERATION OF CROSSED AND SELF-FERTILISED PLANTS.
Capsules from flowers on the crossed plants fertilised by pollen from
another plant, and capsules from flowers on the self-fertilised plants
fertilised with their own pollen, contained seeds in the proportion of :
100 to 94.
