Bavappa and others 224-230http://hdl.handle.net/123456789/3574Leaf growth rate was compared in seedlings of six accessions of cacao {Theobroma cacao L.) differing in their drought tolerant characteristics subjected to water stress. The leaf elongation rate was severely inhibited under drought but failed to indicate any positive relationship with their drought tolerance. Under stress, relative water content of leaf decreased, accompanied by an accumulation of free proline and reduction in nitrate reductase activity. This was more pronounced in drought-susceptible accessions. Epicuticular wax content was generally higher in drought tolerant accessions and did not change appreciably due to stress, white in susceptible accessions the wax content increased considerably. The specific leaf dry weight did not show significant changes.enArticle
