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. FIFTH GENERATION OF CROSSED AND SELF-FERTILISED PLANTS. The crossed plants produced spontaneously a vast number more pods (not actually counted) than the self-fertilised, and these contained seeds in the proportion of : 100 to 89. |
