Column 3: Self-fertilised Plants.
Pot 1 : 14 4/8 : 27 6/8. Pot 1 : 78 4/8 : 8 6/8. Pot 1 : 9 : 56. Pot 2 : 60 4/8 : 16 6/8. Pot 2 : 44 6/8 : 7. Pot 2 : 10 : 50 4/8. Pot 3 : 57 1/8 : 87 (A). Pot 3 : 1 2/8 : 81 2/8 (B). Pot 4 : 6 6/8 : 19. Pot 4 : 31 : 43 2/8. Pot 4 : 69 4/8 : 4. Pot 5 : 99 4/8 : 9 4/8. Pot 5 : 29 2/8 : 3. Total : 511.63 : 413.75. The thirteen crossed plants here average 39.35, and the thirteen self-fertilised plants 31.82 inches in height; or as 100 to 81. But it would be a very much fairer plan to exclude all the starved plants of only 10 inches and under in height; and in this case the nine remaining crossed plants average 53.84, and the seven remaining self-fertilised plants 51.78 inches in height, or as 100 to 96; and this difference is so small that the crossed and self-fertilised plants may be considered as of equal heights. |
