“…Literature reports of inter-species comparisons in Sr concentrations of any isotope were compiled with data we generated for 85 Sr using the Residual Maximum Likelihood (REML) procedure of Broadley et al ( , 2001Broadley et al ( , 2003Broadley et al ( , 2004. Nine publications were identified that reported, without the possibility of foliar contamination, a comparison of concentrations of a Sr isotope in green shoots in two or more plant species growing on the same substrate under identical conditions.…”

A Residual Maximum Likelihood (REML) procedure was used to compile Sr concentrations in 103 plant species from experiments with Sr concentrations in 66 plant species from the literature. There were 14 species in common between experiments and the literature. The REML procedure log e -transformed data and removed absolute differences in Sr concentrations arising from soil factors and exposure times to estimate mean relative Sr concentrations for 155 species. One hundred and forty-two species formed a group with a normal frequency distribution in mean relative Sr concentration. A nested hierarchical analysis of variance (ANOVA) based on the most recent molecular phylogeny of the angiosperms showed that plant species do not behave independently for Sr concentration but that there is a significant phylogenetic effect on mean relative Sr concentrations. Concentrations of Sr in non-Eudicots were significantly less than in Eudicots and there were significant effects on Sr concentrations in the dataset down the phylogenetic hierarchy to the family level. Of the orders in the dataset the Cucurbitales, Lamiales, Saxifragales and Ranunculales had particularly high Sr concentrations and the Liliales, Poales, Myrtales and Fabales particularly low Sr concentrations. Mean relative Sr concentrations in 60 plant species correlated with those reported elsewhere for Ca in the same species, and the frequency distribution and some phylogenetic effects on Sr concentration in plants were similar to those reported for Ca. This analysis of mean relative Sr concentrations in 155 plant species across the angiosperm phylogeny might be helpful for modelling 90 Sr in food chains, predicting radiological doses to flora, and selecting species for phytomonitoring and phytoremediation of 90 Sr.

“…The above relationship was also showed by the results of other studies concerning quality wheat (Gaj 2010(Gaj , 2013. The mechanism of interaction between N and K as well as N and P has been well documented in subject literature (Marschner, et al, 1996;Greenwood and Stone 1998;Broadley, et al, 2004). Uptake of nitrate ions, and then their transport in plants in fact depends on supply of K and requires constant delivery of this nutrient.…”

The aim of the study carried out under field conditions was to evaluate the effect of differentiated phosphorus and potassium fertilization level on nutritional status of winter wheat at stem elongation (BBCH 31) and flowering (BBCH 65) development stages as well as on macronutrient contents in yield obtained (grain and straw). The research was conducted in 2007-2010, within an individual agricultural holding, on lessive soil with medium and high richness in potassium and phosphorus, respectively. The contents of nitrogen, phosphorus, potassium, magnesium and calcium in wheat changed depending on the organ assessed and plant development stage. At BBCH 31, regardless fertilization level, the plants observed were malnourished with potassium, phosphorus and calcium and at the control site -also with nitrogen. Furthermore, there were found significant correlation relationships among the contents of nutrient pairs: nitrogen-potassium, nitrogen-phosphorus, nitrogen-magnesium and nitrogen-calcium. The content of nitrogen in wheat grain and straw differed mainly due to weather conditions during the study. Irrespective of the years of observation, differentiated rates of P and K applied had no significant effect on N accumulation in wheat at full ripening stage. In contrast to nitrogen, the level of P and K fertilization significantly differentiated the contents of phosphorus, potassium and magnesium in wheat grain and straw. In case of calcium, the effect of fertilization factor was indicated only as regards the content of this nutrient in grain. początku strzelania w źdźbło (BBCH31) i kwitnienia (BBCH65) oraz zawartość makroskładników w ziarnie i w słomie pszenicy ozimej. Doświadczenie przeprowadzono w latach 2007-2010 w indywidualnym gospodarstwie rolnym, na glebie płowej o średniej zasobności w potas i wysokiej w fosfor. Zawartości azotu, fosforu, potasu, magnezu i wapnia w pszenicy zmieniały się w zależności od organu rośliny oraz fazy rozwojowej. Niezależnie od poziomu nawożenia mineralnego w fazie BBCH 31 rośliny były niedożywione potasem, fosforem, wapniem, a w stanowisku kontrolnym dodatkowo azotem. Ponadto stwierdzono istotne zależności korelacyjne pomiędzy zawartościami analizowanych par składników: azot -potas, azot -fosfor, azot -magnez oraz azot -wapń. Zawartość azotu w ziarnie i w słomie pszenicy ozimej była zróżnicowana głównie warunkami pogodowymi w latach badań. Zróżnicowane dawki P i K niezależnie od roku badań nie miały również istotnego wpływu na akumulację N w fazie dojrzałości pełnej. W odróżnieniu od azotu, poziom nawożenia mineralnego P i K istotnie różnicował zawartość fosforu, potasu i magnezu w ziarnie i słomie pszenicy. W przypadku zawartości wapnia działanie czynnika nawozowego zaznaczyło się tylko w odniesieniu do zawartości składnika w ziarnie.Słowa kluczowe: zawartość makroskładników, stan odżywienia, dawki fosforu i potasu, pszenica ozima Streszczenie szczegółowe Jednym z podstawowych czynników ograniczających potencjał plonowania pszenicy ozimej jest stan odżywienia roślin w faz...

“…In addition to physiological constraints, tissue concentrations of Ca, Mg and K differ markedly between equivalent tissues of plant species growing in the same environment due to evolutionary factors (18,19,(24)(25)(26) . For example, a considerable proportion of the genetic variation in shoot Ca and Mg, and to a lesser extent K, concentrations occurs at the family level or above.…”

Human individuals require at least 20 inorganic elements ('minerals') for normal functioning. However, much of the world's population is probably deficient in one or more essential minerals and at increased risk of physiological disorders. Addressing these 'hidden hungers' is a challenge for the nutrition and agriculture sectors. Mineral deficiencies among populations are typically identified from dietary surveys because (1) minerals are acquired primarily from dietary sources and (2) (bio)assays of mineral status can be unreliable. While dietary surveys are likely to under-report energy intakes, surveys show that 9 % of all UK and US adults consume Ca and Mg, and 14 % of adults consume K, at quantities below the UK lower reference nutrient intake, and are therefore at risk of deficiency. Low dietary Ca, Mg and K intakes can be caused by energy-malnourishment and by cultural and economic factors driving dietary conservatism. For example, cereal grains routinely displace vegetables and fruits in the diet. Cereal grains have low concentrations of several minerals, notably Ca, as a consequence of their physiology. Low grain mineral concentrations are compounded when cereal crops are grown in soils of low mineral phytoavailability and when grain is processed. In this paper, the impact of increased vegetable consumption and horticultural biofortification, i.e. enhancing crop mineral content through breeding and agronomy, on intakes of the major minerals Ca, Mg and K is assessed. Despite low energy intake from horticultural crops generally, increased vegetable consumption and biofortification would significantly improve dietary intakes of Ca, Mg and K.
