The Results of Yield Tests
The following yield tests were performed in Kanagawa Agricultural
Technology Center. As shown in Figure 4, the flowering seasons of wild-type
and
R3-1
were presented. In the case of the wild-type the plant showed growth
upward. However, in
R3-1
, plant showed growth that was not upward, but
rather tangled. This pattern of stem growth may reflect the difference in
sensitivity to gravity between wild-type and
R3-1
.
The comparison of plant weights dried by blowing air was 2.0-fold higher
in
R3-1
compared to that in the wild-type, as shown in Table 1.
The total plants of wild-type and the mutant,
R3-1
with roots were dried in
the sunny glass green-house as shown in Figure 5. The plant heights after
extension of stems were around 200 cm in both plants. The branching was
more frequent in
R3-1
than those in wild-type. The data of Table 2 including
Narikoma 30 days and Azumino 30 days as references indicated the date of
flower opening in the wild-type was February 13.
Figure 3. The leaves of wild-type and the
R3-1
and
R3-2
mutants under strong sunlight
were subjected to measure relative concentrations of chlorophyll by SPAD photometer
(SPAD-502, Konica Minolta). Five measurements were performed for the 1
st
, 2
nd
, and
3
rd
leaves and the averages with SE were presented.
