TABLE X.—Results of Application of Heat to the axes of Mimosa pudica
—concluded.
| No. of Experi- ment. |
Result. |
| 67 | Application as above, about 0.25 inches from leaf next below and 3 inches from leaf next above. —The axis a strong, woody one; slow, progressive, centrifugal action in all distal leaves; long pause; action in the leaf next below; no further action. |
| 68 | Application as above. —Discolouration and slight exudation; action in all eight dis- tal leaves; action in first leaf below when centrifugal action had almost reached the extremity of the axis; no further action. |
A total of 68 experiments. In all of them centrifugal, propagation occurred,
and in 50 centrifugal propagation only was present. In the 18 cases where
phenomena of centripetal propagation was present, it was very limited in
amount, in no cases advancing beyond the two nearest leaves. Of the total
68 experiments, 41 were carried out in the period from August to December, and
27 from December to March, and each of these groups furnished 9 cases of
centripetal propagation. The phenomenon of centripetal propagation would
from this seem to occur more frequently during dry than moist periods.
TABLE XI.—Results of section of Tips of Axes in Mimosa pudica.
| No. of Experi- ment |
Result. |
| The tips of axes gently cut off by means of a sharp scalpel or pair of scissors. |
|
| 1 | Action in first four leaves beneath the tip no action in the next three leaves action in the five following leaves. |
| 2 | Exudation of a large drop of fluid; long pause; action in leaf next below. |
| 3 | Exudation; long pause, action in two leaves next below. |
| 4 | Action gradually propagated centripetally along the axis as far as it was trace- able. |
