The research will explore how to improve the process by which naturally occurring bacteria
fertilise
plants
.
2
The self-
fertilised
plants
had smaller and paler green leaves than the crossed.
3
Flowers on the self-
fertilised
plants
of the second generation were again
self
-
fertilised
.
4
Salvia coccinea-crossed plants, compared with self-fertilisedplants, produced flowers, in number: 57.
5
Papaver vagum-crossedand self-fertilisedplants, left uncovered, produced capsules, in number: 99.
6
Nevertheless the self-
fertilised
plants
in all three pots flowered before the crossed!
7
Some flowers on the self-
fertilised
plants
of the last generation were also
self
-
fertilised
.
8
Under these circumstances the superiority of the self-
fertilised
plants
cannot be fully trusted.
9
Number of seeds produced by an equal number of naturally-
fertilised
plants
:
-
10
The self-
fertilised
plants
were miserable specimens, whilst the crossed ones looked very vigorous.
11
In the second generation the crossed and self-
fertilised
plants
were nearly equal in height.
12
The superiority of the crossed over the self-
fertilised
plants
was proved in various ways.
13
This results from the superiority of plants crossed in this manner over self-
fertilised
plants
.
14
It is therefore probable that they had some real advantage over the self-
fertilised
plants
.
15
So that the self-
fertilised
plants
,
besides their inferiority in other respects, were more tender.
16
They were not related, or only in a distant degree, to the self-
fertilised
plants
.
