First Experiment 
In the first experiment seed of a bagged individual plant (7G) of 
the Connecticut Broadleaf strain designated as No. 2 was used. The 
seed was sowed in flats Nov. 13, 1912, and on Jan. 4, 1913, the plants 
were transplanted to two-inch pots. On Jan. 28 they were transplanted 
from these pots to a bed of rich clay-loam in the greenhouse at Ar- 
lington, Virginia. From the time the plants were transferred to two- 
inch pots a record was kept of all the leaves produced by marking the 
following leaves: 
4th leaf above the cotyledons marked in January. 
6th " " on February 13. 
8th " " " " March i. 
As soon as the young plants had become established in the bed, 
the moisture relations of one half of the bed were maintained at an 
optimum for the growth of the plants, while the other half of the bed 
was kept relatively dry. The moisture content of the moist soil 
ranged from 18 to 20 percent throughout the experiment, while that 
of the dry soil was kept at 10 to 12 percent. 
The plants in the moist soil were as large and as vigorous in all 
respects as plants growing under the most favorable field conditions. 
The plants in the dry soil became very much stunted, reaching only 
half the height attained by the plants in the moist soil and blossomed 
about 10 days later than these. 
Complete data as to the number of leaves, number of nodes, and 
the character of the inflorescence of the plants grown in the moist 
and dry soil are given in Table I. 
From a comparison of the data for the two sets of plants, the 
following relations are brought out. From column (7), it is seen that 
the average number of nodes from the cotyledons up to but not in- 
cluding the terminal whorl of branches is the same for the normal and 
stunted plants, namely 32.4 and 32.9, respectively. The average 
number of nodes produced by the plants, inclusive of the terminal 
whorl, is also unchanged, namely 36.6 for the normal and 36.1 for the 
stunted plants. An analysis of the various elements of the inflorescence 
as shown in columns (4), (5) and (6) indicates somewhat different 
relations for the two sets of plants. From column (6) it is evident 
that the normal plants produced the largest number of flower branches, 
an average of 8.2, as compared with an average of 5.9 for the stunted 
plants. This reduction in the number of flower branches has taken
