✦ Synopsis
Investigations on the vascular sap of tropical lianas
Summary
Investigations on the electric conductance of the vascular sap of the tropical liana Bauhinia splendens were carried out in the Amazon-rain forest. The values range between 200 and 1000 #S, the pII-vMues between 5.1 and 6.5. The inverse correlation between conductance and pH is due to the high mobility of the H-ion.
In comparison with the soil water in the vicinity of the Bauhinia-roots the content of electrolyts of the sap is 20--100 times higher.
It was not possibel to measure the oxigen content of the Bauhinia sap with the Wink]er-method but in other-not identified-lianas the vascular sap was in all cases undersaturated in oxigen.
