“…1). Delayed development appears to be a consequence of low P availability because this response was also reported for lupine, wheat, and Arabidopsis ( Rodriguez et al, 1994; Ma et al, 2002; Nord and Lynch , 2008). For example, Nord and Lynch (2008) found that low P availability delayed bolting and maturity in seven genotypes of Arabidopsis thaliana .…”

“…For example, Nord and Lynch (2008) found that low P availability delayed bolting and maturity in seven genotypes of Arabidopsis thaliana . It has been suggested that the reason for the delayed leaf maturity was a slower growth rate caused by low P supply ( Rodriguez et al, 1994; Nord and Lynch , 2008), but biochemical and molecular studies support that P deficiency massively impedes growth‐regulating phytohormones ( Zhang et al, 2014). Therefore, it is currently not clear whether the low P levels affected growth directly or indirectly via phytohormones.…”

Phosphorus (P) is often a limiting macronutrient in temperate forests, but knowledge on the phenological and physiological responses of beech (Fagus sylvatica L.) to P deficiency is scarce. In this study, young beech trees were excavated with intact soil cores from two German forests, Unterlüss (LUE) with low soil P and Bad Brückenau (BBR) with high soil P concentrations. The trees were transferred to identical climatic conditions. In the subsequent growth phase phenological stages during bud burst and leaf unfolding were recorded; biomass production and total P concentrations in different tissues were measured. Seasonal fluctuations in photosynthesis and of soluble P in wood and bark exudates were determined. BBR beeches grew faster and produced more and larger leaves than the LUE beeches. Leaf extension and unfolding were delayed in LUE compared with BBR beeches, but not the time point of bud break. All plant tissues of BBR trees contained higher total P concentrations than those of LUE trees. Strong seasonal fluctuations for P in exudates of beech transport tissues, wood and bark, indicated higher P supply in BBR than in LUE plants, especially at the beginning of the growth phase until leaf maturity. Photosynthetic activity of LUE beeches was lower than that of BBR beeches due to stomatal limitations as the result of anatomically smaller stomatal pore widths, but not as the result of acute biochemical limitation of photosynthesis. Our results suggest that developmental retardation and lower photosynthesis under low P availability may be adaptation mechanisms that adjust the acquisition and recycling of P resources to seasonal growth demand.

“…Rodriguez et al (2) found that the duration of the phyllochron on wheat plants growing in two different soils was inversely related to the concentration of P in the shoots early during plant development. Hajabbasi and Schumacher (18) also showed that the addition of P decreased the time to reach a given developmental stage for two genotypes of maize.…”

“…Although it has been stated, for wheat and barley, that temperature and photoperiod are dominant factors influencing the rate of plant development (1), it has also been observed that the nutritional and hydric status of the plant can affect its rate of phenological development (2,3). More re.cently, Squire (4) mentioned that under nutrient deficiency the period between sowing and flowering increases and that of grain filling changes little or decreases.…”

ABSTRACT.· The effect of phosphorus (P) and soil water availability (W) on the growth and development of wheat plants (Triticum aestivum L. cv. Minaret) was studied in a pot experiment. Four levels of P supply (0, 15, 30, and 100 J.lgP/g soil) were applied before sowing. Thirty-four days after sowing (DAS), the pots were kept near 100% of field capacity (FC). From 34 DAS until one week before anthesis (67 DAS), half of the pots were maintained between 60-70% FC. Control pots were kept at 85-95% FC by weighing and watering the pots every two to three days. Shoots were harvested four times before anthesis and twice after. At each harvest, dry matter and P accumulation were measured in leaves, stems, and ears.In this study, thermal time until anthesis was inversely related to the level of P application. Phosphorus additioning affected the allocation of biomass and P in aerial plant organs. Plants growing only with soil P showed a delay in the allocation of dry matter and Pinto leaves and stems with respect to plants fertilized with 100 J.lg P/g of soil. In this study, the final composition of the grain depended on re-mobilization from other plant organs. Evidence of independent re-mobilization of carbohydrates and P towards the ear is presented, and the pattern of plant development as well as the relationships between development and dry matter and P allocation are discussed.

Phosphorus deficiency limits agricultural production in saline soils. Phosphorus fertilizer (P fertilizer) affects soil and crop phosphorus availability, water eutrophication control, and rock phosphate ore resource protection. To clarify the effect of varying types and amounts of fertilizers on the phosphorus availability enhancement at different degrees of saline soil and provide theoretical basis for rational fertilization at high salt soil, a meta‐analysis of 257 datasets from 24 studies was conducted. All studies were from Asia and focused on the effects of P fertilizer on the phosphorus availability in saline soils. P fertilizer application increased soil available phosphorus (AP) and total phosphorus (TP) contents by 49.24% and 56.19% (pQ < 0.05). Further sub‐group analysis revealed that the P fertilizer types, application levels, soil salinity, soil alkalinity, and crop species affected the response variables (AP, TP, above‐ground P content, and yield), as well as derived variables such as the proportion of AP to TP content (AP/TP) and the phosphorus fertilizer utilization efficiency. Intermediate‐level pure organic fertilizer enhanced AP content by 55.66%, while high‐level pure organic fertilizer enhanced AP/TP. Intermediate‐level pure organic fertilizer showed the best effects on above‐ground P content and phosphorus fertilizer utilization efficiency. Mineral plus organic fertilizer at this level achieved the highest yield increase (122.34%). Soil phosphorus availability improved more in mild salinity and pH <8.5 soils. Therefore, integrating the overall responses, applying mineral plus organic fertilizer or pure organic fertilizer at an intermediate level (20–60 kg·ha−1·year−1) for 1–2 years could enhance soil AP content, benefit crop growth, and agricultural productivity in saline soils while managing input costs effectively.
