| Abstract | ||
| An experiment was conducted in lath house at the College of Agriculture , Kerbala University during the growing season of 2011 to study the effect of different concentration of Boron and Iron on shoot system of Apricot seedling . Three replicates were used for each treatment. Boron was used at three levels 0 , 10 , 20 mg/L and three levels of Iron 0 , 10 , 20 mg/L . The seedling were sprayed at two intervals , 15/4 and 30/4/2011 , and they were also sprayed with urea (1g/L) one day before spraying dates. An experiment was conducted according to the Completely Randomized Design (C.R.D.) . and analysis of variance (ANOVA) was based on the least significant difference (P = 0.05) . All measurements were taken at the end of June . Results showed that :- 1- The concentration of 20 mg/L of Boron treatment singnificantly surpassed all other concentrations regarding most studied characters . ( height of seedling ,stem diameter , chlorophyll content in leaves , and dry weight of shoot system ) . at this concentration reached 11.67 cm / seedling , 1.89mm , 32.55 SPAD and 1.99g / seedling respectively . while, there was no significant effect of Boron on the fresh weight of shoot system . 2- Iron treatment at 20mg/L concentration significantly surpassed all other concentrations regarding all studied growth characters . Height of seedling , stem diameter , chlorophyll content in leaves , fresh and dry weights of shoot system, at this concentration reached 11.78cm/ seedling , 1.68mm , 32.78SPAD , 3.52g/ seedling and 1.82g/ seedling , respectively . 3- The interaction between Boron and Iron had no significant effects on the most characters of growth including stem diameter , chlorophyll content , fresh and dry weights of shoot system . However , the only significant effect of this interaction was on Height of seedling where its highest mean was 15.67cm/seedling at the concentration of 20mg/L of Boron and 20mg/L of Iron . | ||
