<![CDATA[ABSTRACT--Cacao is the one important crop in Indonesia. Water stress is perhaps the major factor limiting crop growth. Plant responses to water stress include morphological of biochemical changes. This reserch was aimed studying strtructure and density of non glanduler  trichomes, and leaf area on cacao leaves on drought experiment. The drought studies used throughfall displacment experiment (TDE). The result show that cacao leaves have non glanduler trichomes type stellat. Non Glanduler trichomes were distributed throughtout the vein of leaves with distribution in abaxial parts of the leaves. TDE give non significant effect to trichomes density and Ieaf area. The highest trichomes happened on March 2008 6.9861/cm2. Leaf area on shade Ieaves (273,56 cm2) more higher than sun leaves (235,50 cm2). Keyword : Trichomes non glanduler, cacao leaves, leaf area]]>
