“…A similar result was reported by Moraghan (1993), who found that application of Zn at 8 mg kg -1 soil advanced the appearance of mature bolls by 15 d and increased the yield of flaxseed by 33% in a greenhouse study with a calcareous soil. In contrast to the response of flax, P fertilizers improved seedling growth and increased shoot biomass at heading in durum wheat as compared with the no-P control (P = 0.0009) ( Table 2).…”

. 2007. Growth and nutrient response of flax and durum wheat to phosphorus and zinc fertilizers. Can. J. Plant Sci. 87: 461-470. Flax (Linum usitatissimum L.) and durum wheat (Triticum turgidum L.) are important agricultural crops that enter the human food chain. Effective nutrient management considering nutrient interactions is important in order to increase crop yield and improve crop nutrient concentration. The objective of this study was to investigate the effect of P and Zn fertilizers on the yield and nutritional value of flax and durum wheat. A pot culture experiment conducted in a growth chamber using a calcareous clay-loam soil showed that P fertilizers can restrict flax growth by reducing Zn absorption but can increase the seed yield of both crops by enhanced dry matter translocation to the seed/grain. Among the P sources, commercial monoammonium phosphate (CMAP) and commercial triple superphosphate (CTSP) had similar effects on growth and yield, but different impacts on the nutrient concentrations of both crops, indicating the importance of selecting P source to improve crop quality. Zinc addition with reagent grade P decreased the concentrations of P, K, Ca, Mg and Cu in flax but not in durum wheat. We conclude that proper combination of P and Zn fertilizers is necessary to optimize crop yields, but that P had a proportionally greater effect in promoting yield in durum wheat than in flax. In contrast, Zn had a greater impact on mineral composition in flax than in durum wheat, which can affect the nutritional quality of the crop as a component of the human diet. La culture en pot sur un loam argileux dans un phytotron révèle que les engrais P ralentissent la croissance à cause de l'effet antagoniste du Zn mais augmentent le rendement grainier dans les deux cas grâce à une meilleure translocation de la matière sèche vers la semence ou le grain. Parmi les sources de P, le phosphate d'ammonium diacide et le superphosphate triple vendus dans le commerce ont une incidence analogue sur la croissance et le rendement, mais leur impact sur la concentration d'éléments nutritifs diffère chez les deux plantes, signe qu'il est important de bien choisir la source de P pour améliorer la qualité de la culture. L'addition de Zn à du P de qualité réactif diminue la concentration de P, K, Ca, Mg et Cu dans le lin mais pas dans le blé dur. Les auteurs en concluent qu'une combinaison adéquate des engrais P et Zn est essentielle à l'optimisation du rendement, mais que le P est proportionnellement plus efficace sur le rendement du blé dur que sur celui du lin. En revanche, le Zn agit davantage sur la composition minérale du lin que sur celle du blé, ce qui peut avoir des répercussions sur la qualité nutritive de la culture quand elle est destinée à l'alimentation humaine.

“…On the contrary significant increase was observed for both these minerals during germination of flaxseed varieties. Iron concentration among flaxseed varieties might differ due to interaction of minerals like zinc, cadmium and probably also be due to chlorosis (Moraghan, 1993). Increase in iron and manganese content during germination was also reported by Narina et al (2012) in the flaxseed sprouts.…”

“…Zinc varied significantly among both the raw and germinated flaxseed varieties. Zinc concentration variation among the varieties of flaxseed might be due to initial fertility status of soil and level of fertilizer used (Moraghan, 1993). Zinc showed significant increase in the germinated flaxseed varieties as compared to raw varieties.…”

Four flaxseed varieties viz., JL-27, JL-23, JLS-6, and JLS-9 were germinated for 48 hours. Moisture, fat, protein, and fibre, minerals and antinutritional factors were analyzed in germinated flaxseeds and were compared with the raw. Macro and micro minerals were also assessed for both raw and germinated flaxseeds. Results showed significant variations between raw and germinated flaxseeds. Germinated flaxseeds were more nutritious as compared to raw flaxseeds. Raw flaxseeds were rich in macro minerals whereas germination significantly improved the micro mineral profile of flaxseeds. Germinated JLS-9 seeds revealed maximum significant increase for iron, zinc and manganese. Germination process significantly reduced the cyanogenic glycosides and phytic acid. Maximum reduction for cyanogenic glycosides (82.37%) was noted in JLS-9, whereas phytic acid decline was maximum (52.27%) in JL-23.

Cadmium is a heavy metal present in soils from natural and anthropogenic sources. Plant uptake of Cd at levels present in the soil solution is dependent on a system that is largely metabolically mediated and competitive with the uptake system for Zn and possibly other metals. Much of the Cd taken up by plants is retained in the root, but a portion is translocated to the aerial portions of the plant and into the seed. The amount of Cd accumulated and translocated in plants varies with species and with cultivars within species. Soil, environmental and management factors impact on the amount of Cd accumulated in plants. Potential methods of reducing the accumulation of Cd in crops include reduction of Cd input to the soil system, site selection, management practices which decrease the concentration of Cd in the soil solution and its uptake and translocation by plants, and development and production of plant cultivars with the genetic tendency for low Cd uptake.
