Although goldenrod (Solidago canadensis) is considered an invasive plant in many countries, it is a global cut-flower species. In addition, demand for goldenrod has increased significantly in recent years. Thus, the present study aimed to evaluate the response of Solidago canadensis cv. Tara to brassinosteroids (BRs) at levels of 0.10−3, 10−6, and 10−8 M, and chitosan at 0, 100, 150, and 200 mg/L as a foliar application to increase the quality and quantity of production, and its polyphenolic compounds. Moreover, antibacterial activity and genetic polymorphism for both untreated and the optimally treated goldenrod were investigated. The results showed that the highest mean of growth characteristics was found when plants were treated with BRs at 10−8 M, whereas the longer vase life was obtained using 200 mg/L chitosan. Furthermore, higher pigment values, N, P, K, and total phenolic content, antioxidant capacity, chlorogenic acid, and rutin content were detected on plants treated with 200 mg/L chitosan. In addition, foliar application with 200 mg/L chitosan caused higher antibacterial activity among the control and BRs. The optimal treatment of BR at 10−8 M (89%) showed a low genetic similarity, based on sequence-related amplified polymorphism (SRAP) analysis, comparable with the control and 200 mg/L chitosan. BR at 10−8 M and 200 mg/L chitosan showed a significant enhancement of growth parameters. As a result, it can be concluded that goldenrod, as a herb extract, shows significant promise as a natural preservative in pharmaceutical, food, and cosmetic products.

A pot experiment was conducted during two successive seasons 2017 and 2018 at experimental farm of Faculty of Agriculture, Cairo University, Giza, Egypt. The aim of this study is to determine the ability of Pennisetum setaceum cv. rubrum plant to grow in cadmium (Cd) contaminated soil (100 mg/kg). Also, investigate the effect of citric acid application (1 and 2 mmol/kg) on phyto-extraction of cadmium-contaminated soil. The results clarified that the presence of cadmium (100 mg/kg) in the soil caused low reduction in the herb growth compared to unpolluted soil. The reduction rates in both seasons were 20.33 and 26.47% for herb fresh weight, 5.08 and 14.79% for herb dry weight, 8.86 and 0.0% for number of inflorescences/plant, respectively. The treatment of citric acid 1 mmol/kg increased the Cd content 149.3, 137.5% in the herb, and 221.25, and 170.81% within plant root in both seasons, respectively compared to the control. Also, such treatment raised phenols content in the herb to 102.3 and 93.0% compared to control plants in both seasons, respectively. The results showed that translocation factor (TF) was bigger than one which means that the plants had accumulated the cadmium in their tissues; however the plant tolerated Cd-contaminated soil accompanied with high content in both phenols and catalase enzyme activity. It could be concluded that P. setaceum cv. rubrum is a promising plant for phytoremediation.
