“…The effect of temperature on the host plant is also illustrated by the data of Montanez et al (1995). Soybean DM was significantly less at 15°C than at either 25 or 35°C (Table 2).…”

“…A single stress applied during early vegetative growth had no significant effect on symbiotic performance (Table 4). A single stress applied during flowering or grain filling significantly reduced DM and fixed N, whereas a single stress applied during ripening, while affecting DM, did not reduce symbiotic dependence or fixed N Montanez et al (1995) ( Table 4). When stress was applied at each of the above-mentioned stages, there was a drastic reduction in all measured parameters (Table 4).…”

“…Soil temperature can therefore affect the response to inoculation. Under controlled temperature conditions in the glasshouse, Montanez et al (1995) found that P atm was significantly less at 15°C than at 25°C for three single strains of B. japonicum inoculated on soybean (Glycine max) seed in a soil naturally devoid of Bradyrhizobium (Table 1). P atm at 35°C was significantly less for one of the strains compared with 25°C (Table 1), illustrating a strain x temperature interaction in the absence of competition.…”

After Montanez et al (1995) The performance of the strains was field tested in Quebec in 1990 in the absence of competition in methyl bromide-fumigated soil. Soybean was planted either in mid or late May, and average root-zone temperatures remained well below 20°C until July.…”

“…Based on an examination of the literature, Giller (2001) concluded that there was little likelihood that the results of laboratory screening of strains for a single stress would have much relevance to field performance. Temperature can also affect the response to inoculation through an effect on competitive performance (Montanez et al 1995). For example, when Tal944 (nif − ) was applied to the soil following seedinoculation with three single-strains of B. japonicum, competitive performance differed between 15 and 35°C, as seen by a comparison of P atm in singlestrain and dual-strain inoculation treatments (Table 1).…”

Integrated effects of abiotic stresses on inoculant performance, legume growth and symbiotic dependence estimated by 15N dilution

et al. 2009

Temperature, water, salinity, sodicity, acidity and nutrient disorders are major abiotic stresses that can affect legume growth or the establishment and function of the legume-Rhizobium symbiosis. We have examined the literature where the application of the 15 N isotope dilution methodology permits the effect of individual abiotic stresses to be independently and quantitatively separated into plant growth-mediated and BNF (biological N 2 fixation)-mediated components. The response of the symbiosis to a particular stress depends on a host of factors, including legume genotype, cultivar, Rhizobium inoculant, climatic conditions, and the duration, timing and severity of the stress. Published data are analysed in terms of the above variables and their interactions. As a general rule, severe stress inhibits both legume dry matter (DM) and the proportional dependence of the legume on BNF as a source of N. The symbiosis is resilient to low to moderate stress, but there may still be a penalty on legume DM. Gaps in knowledge are identified, and general guidelines on the identification and amelioration of abiotic stresses are provided.

Climate Change and Plant Abiotic Stress Tolerance

View full text Add to dashboard Cite

As with above-ground tissues, plant roots can be subjected to stressful high temperatures that can limit whole-plant function and decrease crop productivity. Further, with impending climate change, the frequency, duration, and severity of root heat stress will increase. In comparison to shoot function, especially photosynthesis, much less is known regarding heat stress and roots. Most previous research on roots and heat stress has been conducted on detached roots or by heating only roots or parts of root systems (but not shoots too) in intact herbaceous plants, and most past studies on intact plants have imposed chronic heat stress, with few examining effects of abrupt heat stress (e.g., heat waves). Importantly, plant responses to heat stress often differ in detached roots or when only roots are heated, compared to plants wherein both shoots and roots (or shoots only) are heated, and responses to chronic and abrupt heat stress can differ. Hence, many past results do not inform as to how natural heat stress often impacts roots in intact plants or do not inform as to the effects of heat waves on roots. Both chronic and abrupt heat stress can decrease root growth and function, including nutrient and water uptake, and studies in which both roots and shoots were heat-stressed indicate that roots are often more sensitive to heat stress than shoots. Heat stress may affect roots both directly and indirectly, and indirect effects likely involve decreases in shoot carbon provided to roots or changes in root water relations driven by increased shoot water demand, which then affect root growth and nutrient uptake. Interactive effects between heat stress and other global environmental change factors (e.g., elevated carbon dioxide, drought) on roots are likely. We conclude that further research on roots and heat stress is strongly warranted.

Predictions of soybean harvest index evolution and evapotranspiration using STICS crop model

et al. 2021

In the last century, soybean [Glycine max (L.) Merr.] genetic improvements have resulted in increased yield partly due to an increase in harvest index (HI). To account for these genetic improvements, an update of the soybean calibration of the STICS soil‐crop model was carried out. The model was calibrated and evaluated for two sets of soybean plant parameters using datasets from the Ottawa region (ON, Canada); a low HI cultivar calibrated using datasets (1993–2008) of cultivars of maturity groups (MGs) 00 and 0 and a high HI cultivar calibrated with more recent datasets (2016–2017) of cultivars of MGs 0 and I. The model succeeded in reproducing the HI increase. Leaf area index (LAI), shoot biomass, and yield were also well predicted for the high HI cultivars with a normalized root mean square error (NRMSE) of 34, 10, and 14%, respectively, which was a great improvement compared to the default parametrization proposed in STICS for soybean. Under rainfed conditions, accurate simulation of evapotranspiration is a critical point to achieve good model performance. A comparison of the two crop evapotranspiration approaches available in STICS was also carried out. It showed that the resistive approach (NRMSE of 36%) was more efficient than the crop coefficient approach (NRMSE of 67%). This good performance of the model in predicting evapotranspiration allowed the model to perform equally well under water stress and non‐water stressed conditions. The model could therefore be used in future studies to simulate the impact of water stress on soybean growth in eastern Canada.
