“…The observed advance was also more marked than that found in North America by Bradley et al (1999) and Abu-Asab et al (2001). Also the observed trends are stronger that those reported in other Mediterranean areas such as California and Australia (Denisson & Roberts, 2003;Sadrasa & Monzon, 2006). The findings of the present study agree with those reported for other areas of southern Europe, in pointing to a bringing-forward of pollen-season start-dates and peak pollen counts in Olea europaea and Quercus species, and to a lesser extent in Poaceae (García-Mozo et al, 2008a;2008b;2009).…”

“…Time to tillering (Z2.1), time to booting (Z4.9) and time to anthesis (Z 6.1) were recorded [29] (Table 2). Differences in the phenological development between plants grown in pots and rhizoboxes were not expected to be due to the differences in soil volume between the pot experiment (15L) and the rhizoboxes (24L) [30,31], since phenology in wheat is driven by temperature and natural light [32,33].

Characterization of Root and Shoot Traits in Wheat Cultivars with Putative Differences in Root System Size

Abstract:Root system size is a key trait for improving water and nitrogen uptake efficiency in wheat (Triticum aestivum L.). This study aimed (i) to characterize the root system and shoot traits of five wheat cultivars with apparent differences in root system size; (ii) to evaluate whether the apparent differences in root system size observed at early vegetative stages in a previous semi-hydroponic phenotyping experiment are reflected at later phenological stages in plants grown in soil using large rhizoboxes. The five wheat cultivars were grown in a glasshouse in rhizoboxes filled to 1.0 m with field soil. Phenology and shoot traits were measured and root growth and proliferation were mapped to quantify root length density (RLD), root length per plant, root biomass and specific root length (SRL). Wheat cultivars with large root systems had greater root length, more root biomass and thicker roots, particularly in the top 40 cm, than those with small root systems. Cultivars that reached anthesis later had larger root system sizes than those that reached anthesis earlier. Later anthesis allowed more time for root growth and proliferation. Cultivars with large root systems had 25% more leaf area and biomass than those with small root systems, which presumably reflects high canopy photosynthesis to supply the demand for carbon assimilates to roots. Wheat cultivars with contrasting root system sizes at the onset of tillering (Z2.1) in a semi-hydroponic phenotyping system maintained their size ranking at booting (Z4.5) when grown in soil. Phenology, particularly time to anthesis, was associated with root system size.

“…Phenology is sensitive to temperature and an important consequence of rising global temperatures is to hasten crop development in many regions (Sadras and Monzon 2006;Grab and Craparo 2011;Webb et al 2012), while there has been a lengthening of the growing season in high latitudes associated with an earlier onset of the growing season (Jarvis et al 2010;Olesen et al 2011). There is some evidence that altering plant phenology may influence nutrient acquisition (Nord and Lynch 2009).…”

Much of the recent gains in global crop production have been underpinned by greater use of fertilizer, especially nitrogen and phosphorus, and continued improvements in plant nutrition will be needed to meet the increasing demands for food and fiber from a growing world population. Climate change presents many challenges to improvements in nutrient use efficiency by its direct effects on the growth and yield of plants, and hence on nutrient demand, and by its influence on soil nutrient cycling, nutrient availability, and uptake. However, the consequences of climate change on plant nutrition are difficult to predict because of the complexity of the soil-plant-atmosphere system. Empirical data suggests that enhanced as well as reduced nutrient availability and uptake may occur as a result of climate change, depending on the nutrient in question and the component of the climate that changes. Notwithstanding the uncertainty of the effects of climate change on soil nutrient availability and plant nutrient uptake, improvements in nutrient use efficiency will be required to sustain productivity into the future.Over significant areas of the world's arable land, high inputs of nutrients have increased soil nutrient reserves and fertilizer use efficiency is low, while in other
