The fertility was determined in the same manner as in Table 9/F, that is, by the average number of seeds per capsule; and the same remarks as before, with respect to the different proportion of flowers which set capsules when they are cross-fertilised and self-fertilised, are here likewise applicable.
TABLE 9/G.--RELATIVE FERTILITY OF FLOWERS ON CROSSED AND SELF-FERTILISED PLANTS OF THE FIRST OR SOME SUCCEEDING GENERATION; THE FORMER BEING AGAIN FERTILISED WITH POLLEN FROM A DISTINCT PLANT, AND THE LATTER AGAIN WITH THEIR OWN POLLEN. FERTILITY JUDGED OF BY THE AVERAGE NUMBER OF SEEDS PER CAPSULE. FERTILITY OF CROSSED FLOWERS TAKEN AS 100.
Column 1: Name of plant and feature observed.
Column 2: x, in the expression, 100 to x.
Ipomoea purpurea--crossed and self-fertilised flowers on the crossed and self-fertilised plants of the first generation yielded seeds as: 93.
Ipomoea purpurea--crossed and self-fertilised flowers on the crossed and self-fertilised plants of the 3rd generation yielded seeds as: 94.
Ipomoea purpurea--crossed and self-fertilised flowers on the crossed and self-fertilised plants of the 4th generation yielded seeds as: 94.
Ipomoea purpurea--crossed and self-fertilised flowers on the crossed and self-fertilised plants of the 5th generation yielded seeds as: 107.
Mimulus luteus--crossed and self-fertilised flowers on the crossed and self-fertilised plants of the 3rd generation yielded seeds as (by weight): 65.
Mimulus luteus--same plants of the 3rd generation treated in the same manner on the following year yielded seeds as (by weight): 34.
Mimulus luteus--crossed and self-fertilised flowers on the crossed and self-fertilised plants of the 4th generation yielded seeds as (by weight): 40.
Viola tricolor--crossed and self-fertilised flowers on the crossed and self-fertilised plants of the 1st generation yielded seeds as: 69.
Dianthus caryophyllus--crossed and self-fertilised flowers on the crossed and self-fertilised plants of the 1st generation yielded seeds as: 65.
Dianthus caryophyllus--flowers on self-fertilised plants of the 3rd generation crossed by intercrossed plants, and other flowers again self-fertilised yielded seeds as: 97.
Dianthus caryophyllus--flowers on self-fertilised plants of the 3rd generation crossed by a fresh stock, and other flowers again self-fertilised yielded seeds as: 127.
Lathytus odoratus--crossed and self-fertilised flowers on the crossed and self-fertilised plants of the 1st generation yielded seeds as: 65.
Lobelia ramosa--crossed and self-fertilised flowers on the crossed and self-fertilised plants of the 1st generation yielded seeds as (by weight): 60.
Petunia violacea--crossed and self-fertilised flowers on the crossed and self-fertilised plants of the 1st generation yielded seeds as (by weight): 68.
Petunia violacea--crossed and self-fertilised flowers on the crossed and self-fertilised plants of the 4th generation yielded seeds as (by weight): 72.
Petunia violacea--flowers on self-fertilised plants of the 4th generation crossed by a fresh stock, and other flowers again self-fertilised yielded seeds as (by weight): 48.
Nicotiana tabacum--crossed and self-fertilised flowers on the crossed and self-fertilised plants of the 1st generation yielded seeds as (by weight): 97.
Nicotiana tabacum--flowers on self-fertilised plants of the 2nd generation crossed by intercrossed plants, and other flowers again self-fertilised yielded seeds as (by estimation): 110.
Nicotiana tabacum--flowers on self-fertilised plants of the 3rd generation crossed by a fresh stock, and other flowers again self-fertilised yielded seeds as (by estimation): 110.
Anagallis collina--flowers on red variety crossed by a blue variety, and other flowers on the red variety self-fertilised yielded seeds as: 48.
Canna warscewiczi--crossed and self-fertilised flowers on the crossed and self-fertilised plants of three generations taken together yielded seeds as: 85.
As both these tables relate to the fertility of flowers fertilised by pollen from another plant and by their own pollen, they may be considered together.
