TABLE 6/99. Phalaris canariensis (growing in the open ground).
Heights of plants measured in inches.
Column 1: Crossed Plants, twelve tallest.
Column 2: Self-fertilised Plants, twelve tallest.
34 1/8 : 35 2/8.
35 7/8 : 31 1/8.
36 : 33.
35 5/8 : 32.
35 5/8 : 31 5/8.
36 1/8 : 36.
36 6/8 : 33.
38 6/8 : 32.
36 2/8 : 35 1/8.
35 5/8 : 33 5/8.
34 1/8 : 34 2/8.
34 5/8 : 35.
Total : 429.5 : 402.0.
The twelve crossed plants here average 35.78, and the twelve
self-fertilised 33.5 inches in height; or as 100 to 93. In this case the
crossed plants flowered rather before the self-fertilised, and thus
differed from those growing in the pots.]
CHAPTER VII.
SUMMARY OF THE HEIGHTS AND WEIGHTS OF THE CROSSED AND SELF-FERTILISED
PLANTS.
Number of species and plants measured.
Tables given.
Preliminary remarks on the offspring of plants crossed by a fresh stock.
Thirteen cases specially considered.
The effects of crossing a self-fertilised plant either by another
self-fertilised plant or by an intercrossed plant of the old stock.
Summary of the results.
Preliminary remarks on the crossed and self-fertilised plants of the
same stock.
The twenty-six exceptional cases considered, in which the crossed plants
did not exceed greatly in height the self-fertilised.
