CHANGES IN LEAVES AND STEM DIAMETER OF COCOA TREE (Theobroma cacao L.) IN DROUGHT STRESS

TL;DRAbstract

In general, research on plant drought response of cocoa has been done mainly on seedlings. However, information about the response of cocoa tree to drought stress is still very small. The purpose of this resesrch to study the change in leaves number per branch, leaf mass per area ratio (LMA) and stem diameter of the 6 years old cacao tree before and during drought stress period. Drought stress treatment with through fall displacement experiment (TDE) system which is a treatment with through fall displacement experiment (TDE) system which is a method of usng the roof panels plastic are placed under the canopy of trees where the roof can be opened and closed. Experimental design used in this study was completely randomized design with factorial treatment between drought stress treatment (no stress/control; drought stress (roofing) and time (month of sampling). Three designated as a control plot (plot of non-roofing), and three plots defined as a plot roofing. Measurement of variables mad
