Total : 902.63 : 636.13 : 743.13 : 447.38. Some of the remaining seeds of both series, whether or not in a state of germination, were thickly sown on the opposite sides of two very large pots; and the six highest plants on each side of each pot were measured after they had grown to nearly their full height. But their heights were much less than in the former trials, owing to their extremely crowded condition. Even whilst quite young, the crossed seedlings manifestly had much broader and finer leaves than the self-fertilised seedlings. TABLE 6/89. Nicotiana tabacum. Plants of the same parentage as those in Table 6/88, but grown extremely crowded in two large pots. Heights of plants measured in inches. Column 1: Kew-crossed Plants, from pot 2, Table 6/87. Column 2: Plants of the fourth Self-fertilised generation, from pot 2, Table 6/87. |
