| Abstract | ||
| The study was carried out in Al-Rasheedia station-Department of Agricultural Research-Ninava during the winter season 2001-2002. An experiment was done in the field with silty loam soil in order to investigate the effect of different ethephon rates (0, 240, 480, 720, 960) gr./ha a.i on two kinds of Fennel (Foeniculum vulgare) plants which germinated from large and small fruits under rainfed irrigation. The results showed a significant decrease in value of Relative Growth Rate (R.G.R), Plant Growth Rate (P.G.R), BioMass Duration (B.M.D) by increasing the rate of ethephon <480 gr./ha, but on the other side, the values of R.G.R, C.G.R and BMD were increased at the minimum rates of ethephon 240 gr. All plants grown from large fruit indicated higher values in (R.G.R, P.G.R and B.M.D) at plants which grown from small fruits. | ||
