Abstract
By reducing irrigation, the wider stem, water content, and chlorophyll fluorescence of the Malabar chestnut (Pachira macrocarpa) exhibited a downward trend in the number of days. Spectral measurements yielded the same trend. In a single reflectance spectrum, 1450 nm and 1650 nm demonstrate the highest correlation in water content. Comparing the stem water content of Malabar chestnut production in different seasons yielded an average water content of 81.8% in the summer and 66.44% in the autumn. © 2012 American Scientific Publishers.
