“…Some soil samples were used for physicochemical analysis (Table 1) while the remaining samples were filled in standard plastic pots (30cm in diameter) containing equal weights of soil (8kg/pot).To simulate soil pollution, the soil was amended with lead nitrate Pb(NO )2 to produce Pb levels of 50, 100, 200 and 400 mg/l as well as water (control). The soil was watered to field capacity and incubated in green house for 10 days to allow the soil chemical reactions to equilibrate [40]. The organic fertilizer, Acadian, was obtained from Agritech, Dartmout, Nova Scotia, Canada.…”

Lead is one of the hazardous heavy metal pollutants of the environment that originates from various sources. Soil contamination by lead reduces the quality of both soil and cultivated plants which often limits the production of some food products and animal feed. Thus, this study was undertaken to evaluate the effect of a bio-organic fertilizer, namely Acadian, a red algal extract, at recommended dose (RD) in alleviating the deteriorative effect of Pb at 0, 50, 100, 200 and 400 mg/l on tomato (Lycopersicum esculentum) plants. Accordingly, Pb-treated plants showed marked reductions in growth measurements as root and shoot length, fresh and dry weights of shoots,roots and fruits as well as number of leaves and fruits; in photosynthetic rates, stomatal conductance, net intercellular CO? rates (?CO?) and in the contents of each of chlorophyll a, b and total chlorophyll.In addition, with the increase in level of Pb treatment in situ, total sugars, total nitrogen, catalase activity and major nutrient elements (P, K, Ca and Mg) were proportionally declined in both shoots and roots as well as proline of roots. At the other side, Pb treatment raised the levels of each of carotenoids, total soluble sugars, amino nitrogen, total soluble nitrogen, peroxidase, superoxide dismutase, phenols, lipid peroxidation, sodium, lead and iron in both roots and shoots of tomato plants as well as proline of shoots and transpiration rates. When tomato plants were supplemented with the recommended dose of Acadian solely or combined with Pb at all rates, significant increases in all measured growth parameters (shoot and root length, fresh and dry weights of shoots, roots and fruits, number of leaves and fruits), photosynthetic rates, stomatal conductance, ?CO?, the contents of each of chlorophyll a, b, total chlorophyll as well as the contents of total sugars, total soluble sugars, total nitrogen, total soluble nitrogen, amino-N, P, K, Ca and Mg in tomato shoots and roots were obtained. Conversely, Acadian fertilization negatively reduced the carotenoid values, the activity of antioxidant enzymes(catalase, peroxidase and superoxide dismutase), the amounts of phenol, Pb, Na, Fe and the level of lipid peroxidation in both shoots and roots of tomato plants, whereas, it positively affected transpiration rates. On the otherside, when Acadian where added to lead at different rates there were either synergistic increases in the activities of these antioxidant enzymes and the level of phenol and lipid peroxidation or decreases in the carotenoid, Na, Fe and Pb contents as well as transpiration rates. Thus, it is manifested that Acadian can be used to improve the safety, quality and productivity of lead polluted plants.

“…Metal contamination can affect the secondary metabolism of medicinal plants, seriously affecting their quality, safety and efficacy [ 121 , 122 ] and SJW makes no exception. According to various reports [ 123 , 124 , 125 , 126 ] Hypericum perforatum is a fairly good accumulator of heavy metals, Cu 2+ in particular, and this behavior should be examined, both from the safety side and from the possible consequences on secondary metabolism.…”

The increasing diffusion of herbal products is posing new questions: why are products so often different in their composition and efficacy? Which approach is more suitable to increase the biochemical productivity of medicinal plants with large-scale, low-cost solutions? Can the phytochemical profile of a medicinal plant be modulated in order to increase the accumulation of its most valuable constituents? Will polyphenol-rich medicinal crops ever be traded as commodities? Providing a proactive answer to such questions is an extremely hard task, due to the large number of variables involved: intraspecific chemodiversity, plant breeding, ontogenetic stage, post-harvest handling, biotic and abiotic factors, to name but a few. An ideal path in this direction should include the definition of optimum pre-harvesting and post-harvesting conditions and the availability of specific Good Agricultural Practices centered on secondary metabolism enhancement. The first steps to be taken are undoubtedly the evaluation and the organization of scattered data regarding the diverse factors involved in the optimization of medicinal plant cultivation, in order to provide an interdisciplinary overview of main possibilities, weaknesses and drawbacks. This review is intended to be a synopsis of the knowledge on this regard focused on Hypericum perforatum L. (Hypericaceae/Guttiferae) secondary metabolites of phenolic origin, with the aim to provide a reference and suggest an evolution towards the maximization of St. John's Wort bioactive constituents. Factors considered emerged not only from in-field agronomic results, but also from physiological, genetical, biotic, abiotic and phytochemical data that could be scaled up to the application level. To increase quality for final beneficiaries, growers’ profits and ultimately transform phenolic-rich medicinal crops into commodities, the emerging trend suggests an integrated and synergic approach. Agronomy and genetics will need to develop their breeding strategies taking account of the suggestions of phytochemistry, biochemistry, pharmacognosy and pharmacology, without losing sight of the economic balance of the production.

“…Similarly, He et al (2008) found that cadmium stress significantly inhibits germination index and shoot and root growth of rice. Pasquale et al (1995) studied the influence of cadmium on the growth and biological activity of the medicinal plant Coriandrum sativum L. They found that growing plants under cadmium stress significantly reduced shoot and root lengths, resulting in leaf yellowing and in a major alteration in the essential oil quality and quantity. It has been shown that cadmium stress causes many problems in plants including growth and photosynthesis inhibition, alteration in nutrients and formation of free radicals (Sahu et al, 2007).…”

The aim of this study was to assess the effect of Cd 2+ on germination, growth, proline content, lipid peroxidation, and DNA fingerprinting of in vitro grown Cichorium pumilum. Results showed that seed germination was highly inhibited by cadmium (down to 47% at 1600 µM CdCl 2 ). In addition, root and shoot growth showed significant decreases in response to CdCl 2 level. Analysis of proline content and lipid peroxidation showed that with increasing CdCl 2 levels in the growing medium, the amount of proline accumulation and lipid peroxidation increased gradually. Total chlorophyll content was found to increase only at higher tested levels of Cd 2+ (800 and 1600 µM). The results also show that Cd 2+ inhibits callus growth at different levels starting from 50 µM CdCl 2 compared with the control in the callus growth experiment. Callus growth ceased completely at 200 µM CdCl 2 and above. Random amplified polymorphic DNA (RAPD) analysis showed DNA alterations in Cd 2+ -treated C. pumilum microshoots compared with the control. The results of this experiment showed that Cd 2+ stress affects several physiological, biochemical, and molecular processes in C. pumilum.
