“…Hacıseferoğulları et al [24] and Akinwande and Olatunde [26] have also reported significant amounts of K in garlic bulbs, while Mg, Na and Ca were also detected in considerable amounts. In addition, fertilizer application rates and soil properties may have a significant effect on the mineral composition of garlic bulbs, as previously supported by Diriba-Shiferaw et al [15] Põldma et al [27] have also reported that although Se fertilization is recommended for larger bulbs and better antioxidant activity of garlic, high Se application rates can result in the replacement of S by Se in plant metabolism and consequently the decrease in the content of essential macronutrients such as P, K and Ca.…”

“…Vargas et al [29] have reported similar results for Argentinian garlics, where they observed significant differences in the pyruvic acid content not only between different cultivars from the same area but also between the same cultivar grown in different areas. According to Põldma et al [27] sulfur fertilizer rates may have a significant effect on pyruvic acid content and consequently on bulb pungency.…”

Nutritional Value, Chemical Characterization and Bulb Morphology of Greek Garlic Landraces

et al. 2018

Garlic (Allium sativum L.) is an important vegetable crop throughout the world. In Greece there are many areas which have specialized in garlic cultivation through the last decades, considered the main production areas. However, despite the significance of garlic as a food product and the high annual income of this crop, there is a decreasing trend in total cultivated area in Greece, and the local landraces are gradually neglected in favor of new imported genotypes. In the present study, garlic genotypes (local landraces/varieties, imported genotypes, commercial cultivars) from the main production regions of Greece were assessed for their chemical composition and quality (total soluble solids, dry matter content, nutritional value, mineral composition, organic acids, fatty acids content and free sugars content), and bulb morphology. The results of the present study showed significant diversity in quality features and bulb morphology, not only between the genotypes from different growing regions, but also between those of the same region. This result is interesting since it could be implemented for further improvement and valorization of this important vegetable crop through extensive breeding programs within the framework of sustainability and genetic, material conservation.

“…Poldma et al (2011) showed a significant negative correlation between Se and S concentration in Se treated garlic. Similarly, Poldma et al (2013) reported significant reducing S content in onion bulbs as affected by different Se treatments. The contradiction between different studies can be related to either foliar spray of Se that impede uptake competition between Se and S, or associated with applied appropriate doses of Se in some studies, which prevented S assimilation disorder.…”

“…S can be replaced by Se in different organic compounds, especially in sulfuric amino acids, including methionine and cysteine (Terry et al, 2000). Poldma et al (2011) showed a significant negative correlation between Se and S concentration in Se treated garlic. Similarly, Poldma et al (2013) reported significant reducing S content in onion bulbs as affected by different Se treatments.…”

Broccoli is placed in primary selenium (Se) accumulator group plants, which is considered as an important source of Se for providing human daily need. This experiment used an outdoor hydroponic system to evaluate the effects of Se foliar application at the rates of 0, 10, 50, and 100 μg Se/ml concentrations fortnightly. Among yield parameters, the head weight of broccoli was significantly affected. Se treated broccoli plants produced heavier head than the control; however, head weight among three Se concentrations (Se 10 , Se 50 , Se 100 ) was not significantly different. Although most of the chlorophyll fluorescence parameters were not significant, Se treated broccolis maximal fluorescence yield (Fm) was higher than the control. Significant increase in chlorophyll content (chlorophyll a, chlorophyll b and total chlorophyll) was observed as a result of Se treatments. Different Se concentrations did not have positive or negative effects on nitrogen, phosphorus and potassium uptake. Se treatment at 100 μg Se/ml concentration however, contributed to the highest content of sulfur in broccoli head. Se content of broccoli head increased with the increase in sprayed Se concentrations. The highest concentration of Se (1.41 mg Se/kg dry matter) in broccoli head was recorded in Se 100 , which showed significant difference compared with Se 0 and Se 10 .

“…In the literature, there are many scientific reports of ICP-MS analysis for the determination of mineral concentration in food matrices including garlic [5,6,7,8,9,10,11]. Furthermore, nowadays there is great attention paid to the discrimination of protected foodstuffs [12,13,14].…”

We performed a statistical analysis of the concentration of mineral elements, by means of inductively coupled plasma mass spectrometry (ICP-MS), in different varieties of garlic from Spain, Tunisia, and Italy. Nubia Red Garlic (Sicily) is one of the most known Italian varieties that belongs to traditional Italian food products (P.A.T.) of the Ministry of Agriculture, Food, and Forestry. The obtained results suggest that the concentrations of the considered elements may serve as geographical indicators for the discrimination of the origin of the different samples. In particular, we found a relatively high content of Selenium in the garlic variety known as Nubia red garlic, and, indeed, it could be used as an anticarcinogenic agent.
