Table. 1 Soil pH, strontium nitrate (Sr(NO3)2)- and diethylene triamine pentaacetic acid (DTPA)-extractable Zn concentrations and total Zn concentrations of rhizosphere soils collected from the native habitat of D. subsp. pilosum and D. subsp. sumatranum. The number of samples is 4 for each subspecies; pH and concentrations are given as ranges and means
