07 grains of seed. Therefore the
weight of seed from an equal number of crossed and spontaneously
self-fertilised flowers (instead of artificially fertilised as in the
previous case) was as 100 to 58.
The seeds after germinating on sand were planted in pairs on the
opposite sides of four pots, with all the remaining seeds sown crowded
in the opposite sides of a fifth pot; in this latter pot only the
tallest plant on each side was measured. Until the seedlings had grown
about 5 inches in height no difference could be perceived in the two
lots. Both lots flowered at nearly the same time. When they had almost
done flowering, the tallest flower-stem on each plant was measured, as
shown in Table 4/45.
