4-C DNA values of 36 tropical hardwood species belonging to 13 families show a range from 2.08 to 20.07 pg, a 9.64-fold difference. DNA per chromosome values show a 10-fold difference. The minimum range of variation (1.2-fold) is shown by Annonaceae and Sapindaceae while the maximum range (6.23-fold) is shown by Euphorbiaceae, and Fabaceae and Rutaceae show 1.7 and 1.9-fold differences, respectively. On an average, Euphorbiaceae and Rutaceae have been found to possess the largest and the smallest genome sizes respectively.

Keywords: DNA amounts; variability; woody angiosperms
Subjects: Annonaceae; Casuarinaceae; chromosome; DNA amount, genome size; Euphorbiaceae; Fabaceae; genome size, variability; Malvaceae; Myrtaceae; Sterculiaceae
