Effects of Exogenous Calcium and Magnesium on Physio-Hormonal Attributes of Trigonella Foenum-Graecum l. Under Polyethylene Glycol (Peg) Induce Drought Stress
No full textDrought stress is one of the abiotic stresses that adversely affect the plant growth parameters and physio-hormonal attributes. In the current work, we study the adverse effects of induced PEG drought stress in Trigonella foenum-graecum L. in the presence of calcium and magnesium concentration. The experiment was conducted in the botanical garden of Abdul Wali Khan University Mardan in a completely random design. There are eight treatments and one control having each of the trees replicated. The nutrients of calcium and magnesium ratio (4, 2, and 0.18) were added to the plant after 30 days adding the polyethylene glycol of concentration of (0.6 Mpa and 0.2 MPa) for 8 days. The results show that drought stress induced by PEG had a significant effect on the growth and physio-hormonal indices of the plant. It was found that calcium and magnesium both reduce the adverse effects of polyethylene glycol. All treatments helped ascorbic acid, salicylic acid, and auxins to give plant possible growth and development in due time reducing the effects of PEG. Similarly, in enzymatic activities, the maximum lipid peroxidase contents at p >0.05 are found in calcium and magnesium ratio 0.18 and polyethylene glycol 0.2 Mpa. The maximum ascorbic acid peroxidase was found at p>0.05 in Ca/Mg ratio 4. It is concluded from the study that the calcium and magnesium ratio mitigated the adverse effects of polyethylene glycol on Trigonella foenum-graecum L. growth by promoting hormones and enzymatic activities under PEG-induced drought stress

Effects of Polyethylene Glycol (PEG) Simulated Drought Stress on Physio-Agronomic Characteristics in Myhco Variety of Sorghum Bicolor L
No full textThe present study was aimed at determining the differential interactive effects of Ca/Mg quotient and PEG-simulated drought in Sorghum bicolor at the vegetative stage. Sorghum bicolor collected variety Myhco from Persabaq Nowshera were sown in earthen pots (lower inside diameter, 18cm upper inner diameter, 20 cm height and 2 cm thickness) filled with 2 kg of air-dried soil and silt (2:1) pH, moisture content and field capacity in triplicates in the green house of the Department of Botany, University of Peshawar in 2019. The designed experiment contains seven treatments each having three replicates, among these treatments first three are control, the second three are treated Ca/Mg quotient 4+PEG0.6 Ca/Mg quotient 4+PEG0.2, Ca/Mg quotient 2+PEG0.6, Ca/Mg quotient 2+PEG0.2, Ca/Mg quotient 0.18+PEG0.6 Ca/Mg quotient 0.18+PEG0.2, while the last three treatments are treated Ca/Mg quotient 0.18+PEG0.2. Conclusions We conclude that there is a reduction in the agronomy, i.e., leaf area, leaf fresh and dry weight, and a similar reduction also occurred with all other vegetative parts. There is a clear difference between control and PEG drought, and a greater reduction is observed in 0.6 MPa drought. The biochemical characters were also affected in the same manner; a clear reduction was observed in chlorophyll, sugar, and protein, and occurred while the Ca/Mg quotient had no significant effect on Sorghum bicolor L.in Varity myco
