“…Oribi, on the other hand, appeared to be a sensitive cultivar since seed-yield decline was about 500 kg ha -1 lower in the absence of lime. These results are in agreement with previous rapid screening tests for seedlings (Noble, Fey & Lea, 1982) but differ from the screening results of a greenhouse pot trial (Noble, Lea & Fey, 1984) in which vegetative yield only was recorded.…”

“…In previous laboratory and glasshouse pot experiments it was found that soybean genotypes varied in their sensitivity to Al toxicity and to acid, low P soil conditions (Noble, Fey & Lea, 1982;Noble, Lea & Fey, 1984). The objective of this study was to evaluate th,e field response of five soybean cultivars to applications of lime and P on an acid soil.…”

“…Fifteen cultivars (Table 1) were screened in a glasshouse pot experiment with the acid clay loam subsoil of the Normandien series (plinthic Paleudult) used previously for similar experiments with soybeans (Noble, Lea & Fey, 1984). Seven of the cultivars had been screened previously at CIA T for acid tolerance and/or P efficiency.…”

Twelve dry bean cultivars were grown for seven days on filter paper soaked with nutrient solution containing a range of up to 10 mmol AI dm-3 . Differential response to AI toxicity, measured as taproot elongation, occurred at AI concentrations of ~ 2 mmol dm-3 . Fifteen cultivars (including four cultivars classified in terms of AI tolerance by the nutrient-solution method) were grown in pots containing an acid (64% acid saturation of CEC), P-deficient clay loam subsoil (Plinthic Paleudult), differentially treated with Ca(OHh and CaHP0 4 .2H 2 0. After 35 days the plants were classified in terms of tolerance to acid, low P soil conditions, on the basis of relative topgrowth yields. Three of four cultivars screened by both methods were classified identically: lapar-Rai-54 and W126 as tolerant, and BAT331 as sensitive. S. Atr. J. Plant Soil 1985, 2: 115-119Twaalf droeboonkultivars is vir sewe dae op filtreerpapier, deurdrenk met 'n groeimedium wat tot 10 mmol AI dm-3 bevat het, gekweek. Differensiele reaksie op AI-toksisiteit, gemeet deur penwortelverlenging, het by AI-konsentrasies van ~ 2 mmol AI dm -3 plaasgevind. Vyftien kultivars (insluitende vier wat volgens die groeimediummetode vir AItoksisiteit geklassifiseer is) is gekweek in potte, gevul met 'n suur (64% suurversadiging van KUK), P-gebrekkige kleileem-ondergrond (Plinthic Paleudult) wat met Ca(OHh en CaHP0 4 .2H 2 0 behandel is. Die plante is na 35 dae op basis van bogroei in terme van verdraagsaamheid teen suur-en lae-P-grondtoestande geklassifiseer. Drie van die vier kultivars, vol gens albei metodes geklassifiseer, het identies gereageer: lapar-Rai-54 en W126 as bestand, en BAT331 as gevoelig.S.-Atr. Tydskr. Plant Grond 1985, 2: 115-119

“…Researchers have attributed discrepancies in genotype rankings to the different concentrations of Al, P, Ca, Mg, organic acids, and other soil components which greatly affect and potentially mask the expression of genetic tolerance to Al toxicity (Kamprath, 1984; Foy, 1984; Fageria et al, 1988; Blamey et al, 1991). The complexity of soil‐based screening for Al‐tolerance has been sufficiently great that researchers often exercise caution and describe their screening efforts in terms of acid‐soil tolerance rather than Al tolerance per se, even though Al may be the major phytotoxic problem (Nyborg and Hoyt, 1978; Noble et al, 1984; Edmeades et al, 1995). For such reasons, no breeder in North America or Asia is using a soil‐based approach in practical cultivar improvement of Al tolerance in soybean.…”

never been rated for Al tolerance (Palmer et al., 1996). The few soybean germplasm evaluations to date indicate Screening methodology remains a practical barrier in the breeding that soybean can be screened for tolerance to Al-rich of Al-tolerant soybean [Glycine max (L.) Merr.]. Our objectives were to (i) develop a repeatable sand-media culture method for Al toler-acid soil with some degree of success (Sartain and Kamance screening of plants, (ii) compare Al response of genotypes in prath, 1978;Hanson and Kamprath, 1979; Campbell and sand culture to a standard hydroponics-based seedling culture, and Horst and Klotz, 1990;Foy et al., 1992, (iii) establish a practical guide for the use of hydroponics and sand-1993b; Spehar, 1994). However, genotypic rankings for culture screening methods in the selection of Al-tolerant soybean. We Al tolerance often vary among soil types. developed a sand-media culture method and imposed 0 and 450 M Aluminum saturation, the percentage of cation-ex-Al 3؉ activity treatments upon 10 diverse soybean genotypes. The exchange capacity occupied by Al, has been employed in periment employed a randomized complete block design with nine recent decades to classify the potential for Al toxicity replications. Root weight and relative root surface area (RRSA) were in soils, but it has not helped soybean breeders to predict determined at 18 d after transplanting (DAT). In hydroponics, the changes in genotypic rankings for Al tolerance that may genotypes were compared for taproot elongation after 3 d of exposure to 0, 2, and 5 M Al 3؉ activity treatments in a split plot design with occur from one soil type to the next (Kamprath, 1984; six replications. Aluminum stress was imposed successfully (approxi-Fageria et al., 1988). Researchers have attributed dismately 57% of the growth in control) in hydroponics and sand culture, crepancies in genotype rankings to the different concenbut discrepancies between methods were apparent. The hydroponicstrations of Al, P, Ca, Mg, organic acids, and other soil based seedling screen produced an inflated range of genotypic response components which greatly affect and potentially mask and altered Al tolerance rankings in comparison with sand culture.
