Effects of DA-6 on Phosphorus and Potassium Uptakes of Tomato Seedlings under Cadmium Stress

Abstract

In order to study the effect of foliar DA-6 on the phosphorus and potassium content of tomato seedlings under cadmium stress, the pot experiment was used to cultivate ‘Zhongza 9’ tomato in 50 μmol/L CdCl2•2.5H2O nutrient solution. The effects of DA-6 at different concentrations (0, 10, 20, 30 and 40 mg/L) on the phosphorus and potassium uptakes of tomato seedlings under cadmium stress were studied. The results showed that when the DA-6 concentration was 20 mg/L, the phosphorus content in the root and stem of tomato seedlings increased significantly, which were 41.5% and 12.8% higher than the control. In all treatments, when the DA-6 concentration was 10 mg/L, the potassium content of tomato seedling roots, stems and shoots increased significantly, which were 25.4%, 10.0%, and 5.8% higher than the control. In summary, the low-concentration DA-6 treatment had a certain effect on increasing the phosphorus and potassium content of tomato, and there were differences in the optimal concentration of phosphorus and potassium content.

Effects of diethyl aminoethyl hexanoate (DA‐6) on the growth and cadmium accumulation of tomato seedlings

“…The research of shan indicated that DA‐6 increase phosphorus and potassium content in tomato seedlings under Cadmium stress. Different from her research, this experiment studied the effects of DA‐6 on the growth and cadmium accumulation of tomato seedlings 21 …”

“…Different from her research, this experiment studied the effects of DA-6 on the growth and cadmium accumulation of tomato seedlings. 21 Tomato (Lycopersicum esculentum) is an annual or perennial plant in the genus Solanum of the Solanaceae family and produces juicy berries. 22 The ripe, juicy berries of the tomato plant have a unique flavor and contain a variety of nutrients with anti-cancer and anti-aging effects, and are of medicinal value.…”
