Table I. Growth and morphology parameters in wild-type and tdt mutant plants.
Data presented are means ± se (n = 6) obtained in two independent assays; values in boldface for tdt plants were determined by Student’s t test to be significantly different (P < 0.05) from the wild type. LA, Total leaf area; LDM, leaf dry mass; RA, rosette area; RDM, rosette dry mass; SD, stomata density; SI, stomatal index; SLA, specific leaf area.
