Abstract:
A laboratory experiment was conducted to know the effect of water extracts of the vegetation and rootlet of the
Flaveria trinervia on the four levels of concentrations (0,10,20,30%), on germination and growth of seeds of
wheat (Cultivar Hadramout 3). Ten seeds were put in each petri dish, and 5 mL of the extract was added four times
each process. After two weeks, measurements were taken on the studied characteristics(ratio and speed of
germination, length of the plumule and the rootlet, the soft and dry weight of the plumule and the rootlet). The
current study concluded that: the vegetation extract of Flaveria trinervia significantly affected the speed of
germination, the length of the rootlet and the soft weight. While rootlet extract of Flaveria trinervia significantly
affected the rate of germination. Additionally, concentration 20%, significantly affected the percentage of
germination and dry weight of the rootlet, as well, the effect of concentration 30%, significantly on the speed of
germination and the length and the soft weight of the rootlet. It also found that low concentrations (10%) of the
weed Flaveria trinervia extract led to the stimulation of the length of the plumule and the rootlet and the increase
of soft weight of the plumule and the rootlet. There were no significant differences in the effect of the interaction
between Flaveria trinervia extracts and concentrations' levels.
