The present review of gas-exchange studies conducted in rainfed or irrigated field conditions clearly indicates that stomatal conductance (gs) of major crops has been inadvertently increased in the last 50 to 80 years as higher yields were being reached through conventional plant breeding. These findings suggest that high gs rates are critical to optimum growth and yield of modern crops, in particular to crop growth rate (CGR) during seed formation and filling. Several hypotheses are presented that may account for this increase. This review also includes studies in which increases in gs were documented for genetically-engineered plants. However, field evaluations of their gas-exchange performance remain sparse. The main finding of this review is that higher rates of gs should be sought, as we forego the usual consideration of crop plants as single organisms losing water, but rather acknowledge that water does exit a crop canopy along a Soil Plant Atmosphere Continuum (SPAC). In non-limiting or moderately-...

In the present study, the physiological efficiencies of 181 mini-core peanut accessions (genotypes) were evaluated according to variability in their physiological performance in the field during summer (2012). Genotypes were categorized into groups of high, medium, and low physiological activity. Thirty-four genotypes showed high net photosynthetic rate (P N > 33 μmol m−2 s−1), 28 genotypes exhibited high stomatal conductance (g s > 0.54 mmol m−2 s−1), 33 genotypes manifested high transpiration ...

Background Drought is by far the most important environmental factor contributing to yield losses in crops, including soybeans [Glycine max (L.) Merr.]. To address this problem, a gene that encodes an osmotin-like protein isolated from Solanum nigrum var. americanum (SnOLP) driven by the UBQ3 promoter from Arabidopsis thaliana was transferred into the soybean genome by particle bombardment.

Abstract Much effort has been expended to improve irrigation efficiency and drought tolerance of agronomic crops; however, a clear understanding of the physiological mechanisms that interact to decrease source strength and drive yield loss has not been attained. To elucidate the underlying mechanisms contributing to inhibition of net carbon assimilation under drought stress, three cultivars of Gossypium hirsutum were grown in the field under contrasting irrigation regimes during the 2012 and 201...

The objective of this work was to study the responses of two baby lettuce ( Lactuca sativa L.) cultivars, namely, green Paris Island and red Sanguine, to different NaCl concentrations (0, 5, 10, and 20 mM). The study was conducted in a floating system and plants were harvested at the stage of 5-6 leaves, outside leaf 6-10 cm in length (25 and 31 days after sowing for green and red lettuce, respectively). Photosynthetic parameters (photosynthesis rate, stomatal conductance, transpiration rate, an...

Abstract The objective of this study was to characterize physiologically wheat cultivars released in different decades and identify selection criteria for the continued genetic progress in Brazil. Ten cultivars released from 1940 up to 2009 were tested during 2010 and 2011 crop seasons. The following traits were evaluated: grain yield (GY), thousand-kernel weight (TKW), grain number per m −2 (GN), plant height (PH), harvest index (HI), above-ground biomass (BIO), relative Chlorophyll content and...

Global production of rice (Oryza sativa) grain is limited by water availability and the low ‘leaf-level’ photosynthetic capacity of many cultivars. Oryza sativa is extremely susceptible to water-deficits; therefore, predicted increases in the frequency and duration of drought events, combined with future rises in global temperatures and food demand, necessitate the development of more productive and drought tolerant cultivars. We investigated the underlying physiological, isotopic and morphologi...

a b s t r a c t Eight dry-land winter wheat cultivars (Triticum aestivum L.), representative of those widely cultivated from the 1940s to the 2010s in Shaanxi Province of China, were grown in plots that could be sheltered from rain. The plots were subjected to irrigation and drought treatments to identify the agronomic and photosynthetic traits associated with yield progress. Plant height at maturity decreased from 140.7 cm to 79.5 cm from the earliest to the most recent studied cultivar. The yi...

Abstract WUEi (intrinsic water use efficiency) is a complex (multi)-trait, that depends on several physiological processes, driving plant productivity and its relation with a changing environment. Climatic change predictions estimate increases in temperature and drought in the semi-arid regions, rendering improved water use efficiency is a mandatory objective to maintain the current global food supply. The aims of this review were (i) to identify through a meta-analysis the leaf traits mostly re...

Plant phenotyping forms the core of crop breeding, allowing breeders to build on physiological traits and mechanistic science to inform their selection of material for crossing and genetic gain. Recent rapid progress in high-throughput techniques based on machine vision, robotics, and computing (plant phenomics) enables crop physiologists and breeders to quantitatively measure complex and previously intractable traits. By combining these techniques with affordable genomic sequencing and genotypi...

In Chile, durum wheat is cultivated in high-yielding Mediterranean environments, therefore breeding programs have selected cultivars with high yield potential in addition to grain quality. The genetic progress in grain yield (GY) between 1964 and 2010 was 72.8 kg ha−1 per year. GY showed a positive and significant correlation with days to heading, kernels per unit ground area and thousand kernel weight. The gluten and protein content tended to decrease with the year of cultivar release. The corr...

Abstract Knowledge of the agronomic and physiological traits associated with genetic gains in yield is essential to improve understanding of yield-limiting factors and to inform future breeding strategies. The aim of this paper is to dissect the agronomic and physiological traits related to genetic gain and to propose an ideotype with high yield that is best adapted to Spanish Mediterranean environments. Six semi-dwarf (i.e. modern) durum wheat genotypes were grown in a wide range of growing con...

Photosynthesis is essential for plant development as well as crop yield. QTL mapping was conducted for photosynthetic traits such as net photosynthetic rate (PN), stomatal conductance (Cond), inner-cellular carbon dioxide (Ci), transpiration rate (Trmmol), limiting value of the stoma (Ls), and water use efficiency (WUE). A high-density genetic map covering 964.03 cM was developed based on a hybrid population of the Goji (Lycium barbarum L.). The genetic map consisted of 23,967 markers with an av...

Wheat is an important staple crop sensitive to negative effects from elevated tropospheric ozone (O3) concentrations, but the impacts of future O3 concentrations on wheat production in Mexico are unknown. To determine these impacts, the O3-modified DSSAT-NWheat crop model was used to simulate wheat production in Mexico using a baseline scenario with pre-industrial O3 concentrations from 1980 to 2010 and five Global Climate Models (GCMs) under the Representative Concentration Pathway (RCP) 8.5 sc...

Abstract Increased water scarcity can seriously threaten crop productivity worldwide. Therefore, the search for better adapted cultivars to water limitation is needed. Extensive sexual sterility of garlic limits traditional breeding programs and the study of physiological traits provides valuable information for crop selection to stressful conditions. Variability in the functional response of garlic to well-watered (WW) and water deficit (WD) conditions and its relationship with biomass componen...
