“…For optimum crop yield, plants require adequate P from very early growth stages Grant et al, 2001). The success or failure of the early growth stage of developing seedlings is directly related to successful remobilization of stored grain P reserves that were accumulated throughout the ripening period (Guardiola & Sutcliffe, 1971;Le Deunff, 1975;Lawrence et al, 1990;Leonova et al, 2010;Nadeem et al, 2011Nadeem et al, , 2012a. As the hydrolysis of grain P during germination is a major source of inorganic P to support the growing seedlings during early growth stages (Nadeem et al, 2011;2012b) therefore the present study was conducted to investigate the role of P nutrition to the parent plant on the dry weight and P reserves accumulation in maize grains for better selection of seeds.…”

“…Phosphorus accumulates rapidly in grains during ripening along with other substances such as lipids and starch. In seeds, phytate is the main stored form of P (Raboy et al, 1989;Ravindran et al, 1994;Lott et al, 1995;Park et al, 2006;Nadeem et al, 2011) along with inorganic and cellular P (Raboy et al, 2001). External P supply has significant effects on P and dry matter accumulation in grains phosphorus contents are significantly higher in grains treated with HP availability as compared to IP or LP.…”

“…It plays a critical role in plant metabolism, cellular energy transfer, respiration and photosynthesis (Glass et al, 1980;Ozanne, 1980;Deleens et al, 1984;He & Burris, 1992;Usuda & Shimogawara, 1993;Bewley, 1997;Bathellier et al, 2007). In seeds, P is stored primarily in the form of phytate (Lott et al, 1995;Park et al, 2006;Nadeem et al, 2011). Phytate is considered as having anti-nutrient characteristics when consumed by non ruminant animals (Raboy et al, 1989).…”

Nutritional status of grains may vary due to external nutrient supply and their position within parent maize cob. Phosphorus (P) is the least mobile nutrient in the soil and therefore newly growing seedlings are largely dependent on the stored grain P contents which are accumulated during the crop maturity period. Objective of this study was to access the effects of different P applications and grain positions on P and dry matter contents in grains. Phosphorus application and grain position has significant (p<0.05) effects on P contents in grains whereas dry weight and P content are highly correlated. Grain weight and P contents decreased linearly from base to apical position possibly due to flow of nutrients from base towards apical position within cob. Significantly higher grain dry weight (0.35±0.01 g) and P contents (962±57 µg P) are recorded in high P application (92.50 kg ha-1) rate on base position whereas minimum grain dry weight (0.14±0.01 g) and P contents (219±11 µg P) were recorded on apical grain position in low P application (5.60 kg ha-1) rate. The results suggest that for better seedling P nutrition especially in soils of low inherent P, maize grains should be selected from base or middle position where maximum dry weight and P contents are concentrated to support the seedlings to reach at growth at which roots are capable of external P uptake.

“…Generalno, fitati čine značajan deo suve mase semena velikog broja biljnih vrsta, i to između 50 % i 80 % ukupnog P (Lorenz et al, 2007). U zrnu kukuruza, oko 90 % fitata se akumulira u embrionu i oko 10% u aleuronskom sloju (Lott et al, 2009), dok se u endospermu nalazi samo u tragovima (Nadeem et al, 2011).…”

IzvodNedostatak mineralnih elemenata u hrani, može izazvati ozbiljne zdravstvene probleme. Kao jedan od tri najvažnija makroelementa u ishrani biljaka, fosfor učestvuje u nizu procesa u biljci: fotosintezi, disanju, sintezi skroba, transportu ugljenih hidrata i produkata fotosinteze, deobi ćelija i boljem korišćenju vode. Ciljevi ovog istraživanja su uključivali praćenje dinamike nakupljanja neorganskog fosfora (P i ) -prekursora u sintezi fitinske kiseline, i fitinskog fosfora (P phy ), tokom nalivanja zrna dve samooplodne linije kukuruza različitih FAO grupa zrenja -L217 i L773, i utvrđivanje povezanosti sadržaja fosfora u zrnu i agro-morfoloških performansi. Za analizu dinamike sadržaja neorganskog i fitinskog fosfora, uzorci zrna su uzimani: 15-tog, 30-tog, 45-tog i 60-tog dana nakon oplodnje. Na osnovu dobijenih rezultata, uočen je kontinuirani pad sadržaja neorganskog fosfora kod oba genotipa, a najintezivniji pad utvrđen je u prvom intervalu (tj. 15-30 dana) nakon oplodnje, bivajući znatno izraženiji kod linije L217. Takođe, u odnosu na liniju L773, linija L217 je ostvarila viši prinos za 61,8 % u prvom, odnosno za 63,1 % u drugom setvenom roku, respektivno. Srazmerno smanjenju neorganskog fosfora, uočen je trend povećanja fitinskog fosfora kod oba genotipa tokom sva tri intervala merenja. Smanjena dinamika nakupljanja i niži sadržaj fitinskog fosfora (2,635 mg g -1 ) u fazi fiziološke zrelosti, ukazuje da bi se inbred linija L217 mogla smatrati potencijalno poželjnim genotipom za selekciju niskofitinskih hibrida.Ključne reči: neorganski fosfor, fitinski fosfor, prinos zrna, Zea mays L.

Mineralni elementi, među kojim su najvažniji fosfor (P), gvožđe (Fe), magnezijum (Mg) i cink (Zn), obavljaju različite funkcije u biljnim ćelijama, te su neophodni za normalan rast i razvoj biljaka, životinja i ljudi (White and Broadley, 2005;Menkir, 2008). Iako je postizanje visokog i stabilnog prinosa najvažniji i krajnji cilj svih programa savremenog oplemenjivanja biljaka (Malik, 2005), njegovo povećanje veoma često rezultira redukovanim sadržajem mineralnih elemenata u zrnu. Nedostatak ovih elemenata može se prevazići povećanjem sadržaja mineralnih nutritijenata u hrani primenom

Abstract. Ecosystem level nutrient use efficiency (NUE) generally increases with the richness of species or life forms in a community, though, discrepancies may exist at species level. Existence of such discrepancies, phosphorus acquisition efficiency (PAE), phosphorus internal utilization efficiency (PUTIL), phosphorus use efficiency (PUE), quotient of phosphorus utilization (QUTIL) and phosphorus harvest index (PHI) were assessed at species (Corchorus depressus) level with various spatial and temporal factors within the arid area of the Thar Desert, India. These P variables were ordinate and regressed with various bottom up (species richness, relative importance of C. depressus, Shannon and Wiener index, Simpson index, evenness, seed output, percent cover of C. depressus, root length and root collar diameter) and with top down factors (soil organic carbon, nitrogen, moisture, pH and electric conductivity). The relative importance of PAE and PUTIL in the PUE as well as the QUTIL and PHI in the PUTIL were also assessed. ANOVA analysis revealed that all the factors undertaken in the present study (i.e. spatial and temporal events and their interaction) brought significant variation (P<0.001) in PAE, PUTIL, PUE and QUTIL. However, for PHI spatial and temporal events individually brought significant variations, their interaction was non-significant. It emerged that for PUE at low P environmental conditions, PAE was 10-37 times more important than PUTIL. Similarly for PUTIL, QUTIL was 17-56 times more important than PHI. Kaiser-Meyer-Olkin test (0.597) and Bartlett's test of sphericity indicated appropriate use of factor analysis (PCA) and significant correlation between variables in the present study, respectively. Ordination analysis showed lack of correlation between PAE and PUTIL, indicating that selection of one of these should not affect the other. Percent cover of plant, seed output, root length and root collar diameter exhibit various relationships with different P variables. Regression analysis between P variables and community factors revealed that at species level dominance of C. depressus reflects its higher P acquisition efficiency; however as the community diversity (richness, Shannon and Wiener index and evenness) increases the P internal utilization and PUE were inhibited. It can be concluded that P internal utilization and PUE of C. depressus are largely influenced by temporal factors (increase and decrease of community diversity during pulse and non-pulse events, respectively). As a result this species achieved effective nutrient use through temporal partitioning, through which it fulfilled P requirements during low resource availability. Among the soil variables soil nitrogen supported PUTIL, PUE and QUTIL, while soil moisture and soil pH favoured PHI and soil N and PHI showed negative relationship.
