The twelve tallest crossed plants in the two pots belonging to the two
series average here 31.53, and the twelve tallest self-fertilised plants
17.21 inches in height; or as 100 to 54. The plants on both sides, when
fully grown, some time after they had been measured, were cut down close
to the ground and weighed. The twelve crossed plants weighed 21.25
ounces; and the twelve self-fertilised plants only 7.83 ounces; or in
weight as 100 to 37.
The rest of the crossed and self-fertilised seeds from the two
parent-plants (the same as in the last experiment) was sown on the 1st
of July in four long parallel and separate rows in good soil in the open
ground; so that the seedlings were not subjected to any mutual
competition. The summer was wet and unfavourable for their growth.
