“…Seasonal conditions have a significant effect in determining the size of the L response. More significant crop production responses develop when water stress happens during the growing season [6,17,40,52,53]. For example, the highest grain yield response tends to be found under seasons when water stress take place during the vegetative stage and just after anthesis [17].…”

Surface (0–10 cm) and subsoil (soil layers below 10 cm) acidity and resulting aluminum (Al) toxicity reduce crop grain yields. In South Western Australia (SWA), these constraints affect 14.2 million hectares or 53% of the agricultural area. Both lime (L, CaCO3) and gypsum (G, CaSO4) application can decrease the toxic effect of Al, leading to an increase in crop grain yields. Within the region, it is unclear if G alone or the combined use of L and G has a role in alleviating soil acidity in SWA, due to low sulfate S (SO4–S) sorption properties of the soil. We present results from three experiments located in the eastern wheatbelt of SWA, which examined the short-term (ST, 2 growing seasons), medium-term (MT, 3 growing seasons), and long-term (LT, 7 growing seasons over 10 years) effects of L and G on grain yield and plant nutrient concentrations. Despite the rapid leaching of SO4–S and no self-liming impact, it was profitable to apply G, due to the significant ST grain yield responses. The grain yield response to G developed even following relatively dry years, but declined over time due to SO4–S leaching. At the LT experimental site had received no previous L application, whereas, at the ST and MT sites, L had been applied by the grower over the previous 5–10 years. For the LT site, the most profitable treatment for wheat (Triticum aestivum L.) grain yield, was the combined application of 4 t L ha−1 with 2 t G ha−1. At this site, the 0–10 cm soil pHCaCl2 was 4.6, and AlCaCl2 was greater than 2.5 mg kg−1 in the 10–30 cm soil layer. In contrast, at the ST and MT sites, the pHCaCl2 of 0–10 cm soil layer was ≥5.5; it was only profitable to apply G to the MT site where the soil compaction constraint had been removed by deep ripping. The use of L increases soil pHCaCl2, resulting in the improved availability of anions, phosphorus (P) in the LT and molybdenum (Mo) at all sampling times, but reduced availability of cations zinc (Zn) in the LT and manganese (Mn) at all sampling. The application of G reduced Mo concentrations, due to the high SO4–S content of the soil.

“…Drought stress resulted in Al uptake through the root surface and substantial accumulation in leaves (Figures 1H and 4h). Al accumulation in leaves under severe drought stress may negatively affect tree growth and root system development [50]. In our study, the increased accumulation of Na and Al in the leaves of Chinese fir may be negatively affected by drought stress, but the increased uptake and accumulation of P and K by the roots, stems, and leaves could mitigate the adverse effects of drought.…”

Mineral accumulation in plants under drought stress is essential for drought tolerance. The distribution, survival, and growth of Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.), an evergreen conifer, can be affected by climate change, particularly seasonal precipitation and drought. Hence, we designed a drought pot experiment, using 1-year-old Chinese fir plantlets, to evaluate drought effects under simulated mild drought, moderate drought, and severe drought, which corresponds to 60%, 50%, and 40% of soil field maximum moisture capacity, respectively. A treatment of 80% of soil field maximum moisture capacity was used as control. Effects of drought stress on mineral uptake, accumulation, and distribution in Chinese fir organs were determined under different drought stress regimes for 0–45 days. Severe drought stress significantly increased phosphorous (P) and potassium (K) uptake at 15, 30 and 45 days, respectively, within fine (diameter < 2 mm), moderate (diameter 2–5 mm), and large (diameter 5–10 mm) roots. Drought stress decreased magnesium (Mg) and manganese (Mn) uptake by fine roots and increased iron (Fe) uptake in fine and moderate roots but decreased Fe uptake in large roots. Severe drought stress increased P, K, calcium (Ca), Fe, sodium (Na), and aluminum (Al) accumulation in leaves after 45 days and increased Mg and Mn accumulation after 15 days. In stems, severe drought stress increased P, K, Ca, Fe, and Al in the phloem, and P, K, Mg, Na, and Al in the xylem. In branches, P, K, Ca, Fe, and Al concentrations increased in the phloem, and P, Mg, and Mn concentrations increased in the xylem under severe drought stress. Taken together, plants develop strategies to alleviate the adverse effects of drought stress, such as promoting the accumulation of P and K in most organs, regulating minerals concentration in the phloem and xylem, to prevent the occurrence of xylem embolism. The important roles of minerals in response to drought stress should be further evaluated.

“…Changes in root morphology, such as swelling, thickening, and discoloration, are also symptoms of aluminum toxicity (Rahman and Upadhyaya 2020). Siecińska et al (2019) found that Al 3+ in the sensitive line's roots accumulated 5.5 times faster than in the tolerant line's roots. Compared to aluminum-sensitive rice varieties, the roots of aluminumtolerant rice varieties have fewer functional groups and absorb less Al 3+ (Lu et al 2020).…”

Abstract. Tirtana A, Purwoko BP, Dewi IS, Trikoesoemaningtyas. 2021. Selection of upland rice lines in advanced yield trials and response to abiotic stress. Biodiversitas 22: 4694-4703. Breeding programs to obtain superior upland rice varieties with high productivity and adaptive in dryland must be prioritized to maximize the potential of dryland. This research aimed to obtain information on the agronomic performance of upland rice lines in advanced yield trials and select the best lines with high productivity and tolerance to drought stress and aluminum toxicity. Advanced yield trials were conducted from November 2016 until March 2017 in Bogor and Sukabumi using a randomized complete block design, where three replications were nested in the environments. Aluminum and drought stress evaluations were conducted at Muara Research Station, Bogor, in May-June 2018 and September-October 2018. Based on the selection index, twelve lines were selected with superior agronomic characters and high yield potential. These lines had characteristics as follows: days to harvesting (110.2-116.0 days), number of filled grains (70.6-101.3 grains), number of unfilled grains (27.9-58.4 grains), and productivity (2.2-2.9 tons ha-1). Evaluation of drought tolerance showed four lines with better drought tolerance than the drought-sensitive check IR20. The aluminum tolerance evaluation obtained two tolerant lines and nine lines with moderate responses to aluminum toxicity. The selected lines need to be further evaluated in multilocation trials.
