Darwin, Charles, 1809-1882

"Effects of Cross and Self Fertilisation in the Vegetable Kingdom"


Pot 2 : 20 3/8 : 15 2/8 :: 22 1/8 : 18 :: 21 : 17 3/8 : -3 5/8.
Pot 3 : 18 2/8 : 16 4/8 :: 21 5/8 : 16 4/8 :: 20 3/8 : 16 4/8 : -3 7/8.
Pot 3 : 21 5/8 : 18 :: 20 3/8 : 16 2/8 :: 19 1/8 : 16 2/8 : -2 7/8.
Pot 3 : 23 2/8 : 16 2/8 :: 18 2/8 : 15 2/8 :: 18 2/8 : 15 4/8 : -2 6/8.
Pot 3 : - : - :: - : - :: 12 : 15 2/8 : +3 2/8.
Pot 3 : 21 : 18 :: 23 : 18 :: 12 : 12 6/8 : +0 6/8.
Pot 4 : 22 1/8 : 12 6/8 :: 22 1/8 : 18.
Pot 4 : 23 : 15 4/8 :: 21 : 15 4/8.
Pot 4 : 12 : 18 :: 12 : 12 6/8.
"The observations as I received them are shown in Table 1/1, Columns 2
and 3, where they certainly have no prima facie appearance of
regularity. But as soon as we arrange them the in order of their
magnitudes, as in columns 4 and 5, the case is materially altered. We
now see, with few exceptions, that the largest plant on the crossed side
in each pot exceeds the largest plant on the self-fertilised side, that
the second exceeds the second, the third the third, and so on. Out of
the fifteen cases in the table, there are only two exceptions to this
rule. We may therefore confidently affirm that a crossed series will
always be found to exceed a self-fertilised series, within the range of
the conditions under which the present experiment has been made."
TABLE 1/2.
Column 1: Number (Name) of Pot.
Column 2: Crossed.
