pot experiment was carried out to investigate the effects of ethylenediaminetetraacetic acid (edta) on some morphological characteristics of thlaspi caerulescens l., and also on the accumulation of lead (pb) and zinc (zn) in roots and shoots of t. caerulescens l.. experiments were then set up in three treated pots with doses of 3, 6 and 9 mmol kg-1 of edta and control pots (c: uncontaminated so...

in order to investigate the morphological reactions of cutting of damask rose to iba (indole butyric acid) in different times, an experiment was done in a factorial experiment based on rcd and three times with three replications and 10 observations per each replication. in this experiment, the simple effects of iba, time and their interaction effects were measured against morphological properti...

the geometric morphometrics method was applied to study the morphological differences in 95 specimens of kura barbel (barbus lacerta, heckel 1834) collected from three riverine ecosystems of the sefidrud basin, viz. taleghan, totkabon and kloraz rivers.  for this purpose, the left sides of the specimens were photographed. then, 14 landmark-points were defined and digitized on 2d pictures using ...
