Abstract

Sunflower (Helianthus annuus L.) is one the most important oilseed crops in the world and also in Iran. PHOSPHORUS application on tolerance of SUNFLOWER to SALINITY was investigated. Experiments were carried out in environment. A 3×3 factorial experiment in completely randomized design with 3 replications was used. The first factor consisted of 3 levels NaCl (0, 50, 100 mM) and the second factores consisted of 3 levels PHOSPHORUS (0, 1 and 5 mM P). One germinated seed of SUNFLOWER transferred to culture jars and treatments were applied at 2-leaf stage of the plants. After three weeks, the plants were harvested. The GROWTH PARAMETERS including shoot fresh and dry weights, leaf number were determined. Leaf area was determined with leaf area meter (Delta T MK2 model). One gram fresh leaf was hemogenized in 80% aceton and filtered. B-carotene and XANTHOPHYLL were extracted with diethyl ether and petrolium ether. SOLUBLE AND NON SOLUBLE SUGARS were determined by the Phenol-acid sulfuric method. PROTEIN measurment was done with the foline reagent. All of the extraction were read with spectrophotometer (Shimadzo UV-120-02) at appropriate spectrums. The results indicates that GROWTH PARAMETERS, CHLOROPHYLL a and B- carotene of SUNFLOWER cv. Record were increased at moderate SALINITY level (50 mM NaCl) in comparison with control. SALINITY effect on CHLOROPHYLL b and XANTHOPHYLL was not significant. Increasing salt concentration, increased soluble sugar and PROTEIN, but had no significant effect on non soluble sugar. At 100 mM NaCl, application of PHOSPHORUS (specially at 1 mM) increased the GROWTH PARAMETERS, SOLUBLE AND NON SOLUBLE SUGARS and PROTEIN. PHOSPHORUS had little effect on the CHLOROPHYLL and carotenoids. According to the results of this study, SUNFLOWER cv. Record is a moderately salt tolerant crop and it is likely to show better performance under moderate SALINITY status than non-saline conditions and PHOSPHORUS application can moderate the adverse effects of SALINITY on SUNFLOWER.
