| Abstract | ||
| An experiment was conducted in lathhouse at the College of Agriculture, Kerbala University during the growing season of 2011-2012 to study the effect of different concectrations of Boron and Iron on shoot and root system of olive seedlings. Three replicates were used for each treatment. Boron was used at three levels (0,30,60) mg/L and three levels of Iron (0,50,100) mg/L, The seedlings were sprayed at two intervals,15/10 and 30/10/2011, and they were irrigated one day before spraying dates. The experiment was conducted according to the Completely Randomized Design (C.R.D) and analysis of variance (ANOVA) was based on L.S.D 0.05 .All measurements were taken at the mid of may,And the results showed as follow . 1- The concentration of Boron at 60 mg /L signigicantly surpassed all other concentrations regarding all studied characters ( height of seedling , stem diameter , chlorophyll content in leaves , Boron concentration in leaves , iron concentration in leaves ,root length , fresh weigh of root system and dry weight of root system) . Which gave ( 57.44 cm,5.45mm,68.98 SPAD ,53.61 mg/L ,45.95 mg/L ,41.56 cm,32.14 g and 14.46g), respectively . 2- Iron treatment at 100 mg / L concentration significantly surpassed all other concentration regarding all studied growth characters too, Which gave (53.44 cm, 5.17mm,67.05 SPAD , 49.67 mg/L, 38.75 mg/L, 37.11 cm , 26.72g and 10.98 g), respectively . 3-The interaction between Boron and Iron had no significant effects on stem diameter ,Boron concentration in leaves ,Iron concentration in leaves ,root length and dry weight of root system,however , the significant effect of this interaction was on height of seedling , chlorophyll content in leaves and fresh weight of root system.The interaction of 60 mg/L of Boron and 100 mg /L of Iron gave (64.33 cm, 74.33 SPAD and 37.70g ), respectively | ||
