Abstract

Embolism are recognized as naturally event which constraints affecting plants regularly exposed to water stress. The objective of the research is to analyze embolism of cocoa and G.sepium root on dessication stress with throughfall displacement experiment (TDE) system that done from December 2006-February 2007. The observation conducted after 5-7 months and 13 month roofing. To determine embolism was calculated with Sperry et al., (1988) method. The results showed that dessication stress with TDE system during 13 month not cause embolism difference on cocoa and also G. sepium root that exposed or not in dessication stress. But the embolism change more infuenced by season. At soil deepnes 20 cm embolism on cocoa root was 18 - 45% and G. sepium was 9 - 71%.
