摘要：
The formation of a red complex between boron and the quinalizarin reagent was investigated and used as the basis for a simple and sensitive spectrophotometric method for boron in date cultivars. At 620 nm, the absorbance was linear (r = 0.999) over the 0.25-2.5 mug/mL concentration range. The molar absorptivity was found to be 2.23 X 10(3)mol-1cm-1 and the relative standard deviation for 10 replicates (1.0 mug/mL) was 0.97%.
