The application of flowering plants is the basis of urban forest construction. A newly-found flowering hyperaccumulator is crucial for remediating urban contaminated soil sustainably by cadmium (Cd). This study evaluated growth responses, Cd uptake and bioaccumulation characteristics of seven urban flowering plants. Based on growth responses of these plants, Calendula officinalis L. showed high tolerance to at least 100 mg kg−1 Cd, in terms of significant increase in biomass and with no obvious changes in height. After 60 d exposure to 100 mg kg−1 Cd, the accumulated Cd in shoots of the plant reached 279.51 ± 13.67 μg g−1 DW, which is above the critical value defined for a hyperaccumulator (100 μg g−1 DW for Cd). Meanwhile, the plant could accumulate Cd to as much as 926.68 ± 29.11 μg g−1 DW in root and 1206.19 ± 23.06 μg g−1 DW in plant, and had higher Cd uptake and bioaccumulation values. According to these traits, it is shown that Calendula officinalis L. can become a potential Cd-hyperaccumulator for phytoremediation. By contrast, Dianthus caryophyllus L. is very sensitive to Cd stress in terms of significantly decreased biomass, height and Cd uptake, indicating the plant is considered as a Cd-bioindicator.

Growth Characters

Salt stress is one of the main factors limiting plant growth and yield globally. Seed priming technique with different chemicals including β-aminobutyric acid (BABA) is found to be effective in enhancing plant growth and development under biotic and abiotic stresses. Scarce reports have been found about BABA seed priming in medicinal plants under stress conditions; however, several studies have been conducted on other crops but have not made an in-depth study to investigate biochemical and physiological changes. In current study the shoot growth, relative water content (RWC), chlorophyll content, stomatal conductance, nutrient content (N, P, K, Na and Cl), proline, malondialdehyde (MDA), hydrogen peroxide (H2O2) content, antioxidants enzymes (CAT, SOD and POD), membrane stability index (MSI), total phenolic and flavonoids contents lipid peroxidation and membrane permeability were investigated in Calendula officinalis L. leaves due to BABA seed priming and/or salt stress treatment. Salt stress treatment significantly reduced the growth characters, inflorescence number as well as its fresh and dry weights, N, P and K contents in leaves, RWC, chlorophyll content, stomatal conductance, MSI and total phenolic and flavonoids contents of pot marigold. However, proline content, MDA accumulation, H2O2 content and antioxidant enzyme activity (CAT, SOD and POD) were increased due to salt stress. On the other hand, seed priming with BABA significantly improved the growth characters, inflorescence attributes and the previously mentioned physiological and biochemical parameters investigated relative to the control. Applying seed priming under salt stress conditions significantly mitigated the negative effects of salinity and enhanced the growth and productivity of pot marigold and therefore was suggested to be an effective technique prior to cultivation.

Shoot And Root Growth

The impact of salt stress on the growth and phosphorus utilization efficiency (PUE) of two leguminous species: Retama monosperma and Acacia gummifera was studied. The effectiveness of arbuscular mycorrhizal fungi (AMF) to mitigate salt stress was furthermore assessed. Growth, N and P tissue concentrations, mycorrhizal root colonization frequency and intensity, and P utilization efficiency (PUE) in the absence or presence of AMF were evaluated under no salt (0 mM L−1) and three salt (NaCl) concentrations of (25, 50 and 100 mM L−1) using a natural sterilized soil. A significant difference in mycorrhizal colonization intensity, root-to-shoot ratio, P uptake, PUE, and N uptake was observed between the legume species. Salt stress inhibited the shoot and root growth, and reduced P and N uptake by the legume species. Mycorrhizal inoculation aided to mitigate the effects of salt stress with an average increase of shoot and root growth responses by 35% and 32% in the inoculated than in the non-inoculated A. gummifera treatments. The average shoot and root growth responses were 37% and 45% higher in the inoculated compared to the non-inoculated treatments of R. monosperma. Average mycorrhizal shoot and root P uptake responses were 66% and 68% under A. gummifera, and 40% and 95% under R. monosperma, respectively. Mycorrhizal inoculated treatments consistently maintained lower PUE in the roots. The results provide insights for further investigations on the AMF conferred mechanisms to salt stress tolerance response by A. gummifera and R. monosperma, to enable the development of effective technologies for sustainable afforestation and reforestation programs in the Atlantic coast of Morocco.
