The Department of Biology Holds a Seminar for a Doctoral Student on the Effect of Adding Auxin (IAA) and Nano-chelated Zinc on Wheat Plant Tolerance to Salt Stress
As part of the series of scientific activities organized by the Department of Biology, a seminar was held for doctoral student (Ghofran Habib Omran) entitled “The Effect of Adding Auxin (IAA) and Nanozinc Chelate on Wheat Plant Tolerance to Salt Stress.” The seminar was supervised by (Prof. Dr. Qais Hussein Al-Samak) and (Asst. Prof. Dr. Ban Musa Hassan). This seminar aimed to study the effect of adding auxin (IAA) and nano-chelated zinc on wheat (Triticum aestivum L.) to salt stress resulting from irrigation with saline water. The scarcity of water resources in Iraq, in addition to the use of poor-quality water for irrigation, are major challenges that negatively impact agricultural production, especially the strategic wheat crop. The research results also showed that zinc, an essential microelement, plays a significant role in protein metabolism and plant growth. Nanofertilizers are emerging as an effective alternative to conventional fertilizers, as they allow for control over the rate of nutrient release and the quantities added, thus reducing side effects on the plant and consumer. The experiment was conducted at the College of Agriculture at the University of Karbala using Ibaa 99 wheat grains. Auxin (IAA) solution was prepared at a concentration of 20 mg/L and sprayed on the leaves in two stages. A nanozinc solution was also prepared at concentrations of 1 g/L and 2 g/L. The plants were irrigated with saline water at levels of 2, 4, and 8 dS, using standard methods to estimate the leaf content of zinc, nitrogen, phosphorus, potassium, and protein in the grains.
