Effects of sulphate level in the nutrient solution on plant growth and sulphur content in tomato plants
نویسنده
چکیده
The effect of various concentrations of sulphates in the nutrient solutions (I – 200, II – 400, and III – 600 mg SO4 2dm) on sulphur content in plants as well as plant height and leaf area of tomato plants grown with nutrient film technique (NFT) were investigated. Total-S and S-SO4 levels were determined in the leaf blades of the upper, medium and lower plant parts, during 3 phases of tomato growth and also in the roots. The increase of sulphate concentration in the nutrient solution resulted in the increase of total-S and S-SO4 levels in all analysed plant parts, regardless of the growth phase. There were no significant effects of different SO4 2levels in the nutrient solution on tomato growth and leaf area.

Salinity plays an important role in the reduction of tomato growth, especially in arid and semi-arid regions. Nitrogen (N) may increase tomato tolerance to salt stress by increasing plant growth. In order to investigate the interaction effect of salinity and nitrogen on tomato growth, fruit quality, and micronutrient concentration in tomato plants, a hydroponic experiment was conducted in a com...
