In addition to these plants, three crossed plants were planted separately in three large pots, and three self-fertilised plants in three other large pots, so that they were not exposed to any competition; and now the self-fertilised plants exceeded the crossed in height by a little, for the three crossed averaged 55.91, and the three self-fertilised 59.16 inches; or as 100 to 106. CROSSED AND SELF-FERTILISED PLANTS OF THE THIRD GENERATION. TABLE 6/86. Nicotiana tabacum (third generation). Seedlings from the self-fertilised plant A in pot 3, Table 6/85, of the last or second generation. Heights of plants measured in inches. Column 1: Number (Name) of Pot. Column 2: From Self-fertilised Plant, crossed by a Crossed Plant. Column 3: From Self-fertilised Plant again self-fertilised, forming the third Self-fertilised generation. Pot 1 : 100 2/8 : 98. Pot 1 : 91 : 79. Pot 2 : 110 2/8 : 59 1/8. Pot 2 : 100 4/8 : 66 6/8. Pot 3 : 104 : 79 6/8. |
