“…Increasing B levels in the NS significantly boosted the B content in edible parts of purslane (Figure 2) with no differences in yield and DW (Table 1). Our results are in agreement with several authors [34][35][36][37][38][39], who reported significant increases of B in different species as a consequence of high concentrations of this element in growing media and/or NS. In fact, B moves from the roots with the transpiration stream and accumulates in growing points of leaves and stems [40].…”

Boron Biofortification of Portulaca oleracea L. through Soilless Cultivation for a New Tailored Crop

Purslane (Portulaca oleracea L.) is a wild edible plant, traditionally consumed in the Mediterranean area and recently proposed as a new ready-to-eat vegetable; it is also called the “vegetable for long life” because of the high contents of several healthy compounds. Although boron (B) is not considered to be essential for humans, a daily intake of about 2 mg to obtain positive effects on aging in adult men and women has been suggested. In this study, two genotypes of purslane (wild collected and commercial variety) are grown by using a hydroponic system with three boron (B) levels in the nutrient solution (NS) (0.3 mg/L—control, 3 mg/L—low level of biofortification, and 6 mg/L—high level of biofortification) in order to increase the B content in the edible parts of the plant. The crop yield, color traits, and content of glucose, fructose, total phenols, chlorophylls, carotenoids, mineral elements (Al, B, Ca, Cr, Fe, K, Mg, Mn, Na, and Zn), nitrate, and oxalate are analyzed. Independent of the genotype, the B content in edible purslane was successfully increased in comparison with the control, obtaining 1.8- to 10.7-fold higher values of B tissue concentrations by using, respectively, 3 and 6 mg/L of B in the NS without affecting crop performances. From a nutritional point of view, the average daily intake of B could be satisfied by consuming about 75 or 48 g of purslane, grown by using 3 and 6 mg/L B level in the NS, respectively. Apart from B and Fe, the content of mineral elements in edible parts of purslane was not strongly influenced by different B levels in the NS but it was affected by genotypes. A lower sugar content was found in wild purslane grown with the highest B level. A higher content of both chlorophylls and carotenoids was found in the control but only for the commercial genotype. No differences in oxalate content were observed among B levels in the NS, while only in the case of wild genotype, we found a lower nitrate content when a B concentration of 3 mg/L was used in the NS. In conclusion, we demonstrated the possibility of using the floating hydroponic system, combined with specific B concentrations in the NS composition, as a method to calibrate the B uptake in edible parts of purslane.

“…In this study, shoot-root fresh and dry weight showed an alteration according to boron dose and soil type during boron stress and decreased compared to control plants. A similar result has been reported in corn (Güneş et al, 2000a), tomato (Güneş et al, 2000b), potato (Ayvaz, 2009), purslane plants (Samet and Çakılı, 2016;2019) for shoot fresh weight, in pepper (Akıncı, 2006;Eraslan et al, 2007), corn (Palta and Gezgin, 2011), canola (Koohkan and Maftoun, 2016; purslane plants (Samet and Çakılı, 2016;2019) and buckwheat plant (Yazıcı and Korkmaz, 2020) for shoot dry weight.…”

Boron toxicity in agricultural lands limits plant breeding as a plant nutrition problem. Some plants are able to tolerate high levels of heavy metals at potentially toxic doses, accumulate them in their bodies and remove them from the soil. In this study, it was aimed to determine the morphological and physiological responses of ornamental cabbage in phytoremediation against boron toxicity. This study was conducted under controlled greenhouse conditions, 4 different boron doses (0, 10, 25, and 50 mg kg -1 B) were applied to 2 different soil structures (acidic (S1) and alkaline (S2) soils). Toxicity symptoms were appeared at 50 mg kg -1 B. At alkaline soil, plant weights and visual properties of plants were found to be low in quality. Results show that as the boron dose increased, shoot-root fresh and dry weight, stomatal conductance, chlorophyll content, relative water content (RWC) were decreased. Boron accumulation in the shoot, root and whole plant was at 50 mg kg -1 B. As a result, it is understood that ornamental cabbage used for decontamination of boron element by phytoremediation method for the first time in this study. We suggest that it has a potential to as hyper-accumulator plant for the remediation of boron-contaminated soil.

“…However, in the present study, the close relation between Zn efficiency and B tolerance could not be explained by the differences in B concentration in shoots. Also Grewal et al (28) in oilseed rape and Günes et al (29) in tomato showed increases in B concentration in shoots under Zn deficiency, but these increases in B concentration in Zn-deficient plants were attributable to a concentration effect due to reduced growth, rather than the 1826 TORUN ET AL. On average of 25 wheat cultivars, Zn fertilization tended to increase B concentration in the shoot.…”
