“…Thus, inbred C I 03 could be classified as susceptible to low pH and inbred Val7 could be classified as tolerant. This agrees with the finding of other workers (Lutz et al, 1971; Rhue and Grogan, 1977;and Rhue et. al., 1978).…”

Plants differ in their ability to take up nutrients. Developing genotypes efficient in utilizing nutrients from acid or low nutrient soils would aid in growing crops successfully when mineral supplementation is not feasible. This study was conducted in the greenhouse using mine spoil soil of initial pH 3.9 with variables of genetic sources of corn (Zea mays L.) and lime rates. Genetic source variability was more pronounced under stress conditions (low pH) than under nonstress conditions. The genetic sources PI270083, PI270080, and Va17 showed higher tolerance to acidic conditions than others. Inbred C105, highly susceptible to low pH, showed the most visual root damage as well as the lowest relative dry matter yield. Aluminum concentration in the plant tissue did not vary significantly with lime level; however, exchangeable Al in the soil decreased drastically as the level of lime application increased. Manganese in the plant tissue and in the soil (DTPA extractable) both decreased with increased lime rate. Dry matter yield decreased significantly at 16 500 kg ha−1 of lime compared with 8000 kg ha−1. Phosphorus concentration decreased in the plant as well as in the soil (Bray P‐1 extractable) at 16 500 kg ha−1 lime, which could have been a factor in reduced yield. Genetic source by lime interaction was significant for Ca, Mg, Al, and Mn concentration indicating that selection under different pH levels would be productive.

“…The influence of pH on plants has been investigated using soil or nutrient solution as the plant growth medium. Nutrient solutions are commonly preferred (Sherchan et al, 1983;Lutz et al, 1971;Siraj-Ali et al, 1987;Kim et al, 1985;Islam, 1980;, because there is less confounding of pH with pH-induced nutrient excesses or deficiencies.…”

Growth and Nutrient Composition of Maize Genotypes in Acid Nutrient Solutions

Crop production in acid soils may be limited by several factors, including low pH. Development of acid‐tolerant cultivars requires information about differences in tolerance to low pH among crop genotypes. To determine whether differential responses to nutrient solution pH occurred among seven maize (Zea mays L.) genotypes, seedlings were grown in a growth chamber in flowing solutions at pH levels ranging from 3.3 to 6.7. Top weights, root lengths and weights, and concentrations of Ca, Mg, Fe, Zn, and Mn in plant tops were determined after 12 d. All genotypes grew well with pH of 4.0 to 5.5, with maximum dry weights of plant tops at pH 4.6 for most of the genotypes. However, all genotypes had necrotic root tips and decreased root lengths at pH 3.3, with relative root lengths (length at pH 3.3/maximum length) ranging from 0.26 to 0.55. Root weights were relatively unaffected by solution pH, but top weights decreased markedly at both pH extremes. Iron concentrations of all genotypes were decreased at pH 6.7, and interveinal chlorosis, resembling Fe deficiency, appeared in the younger leaves. Relative top weights (weight at pH 3.3/maximum weight) averaged 0.79 for Trinidad Grpl&2 and ‘PDMR Comp 1’ and 0.58 for ‘UPCA Varl’, ‘PDMR3’, Kalimpos, and Dikit at pH 3.3, and relative top weights among genotypes were positively correlated (r = 0.85) with Mn concentrations in tops. Based on relative top weight at pH 3.3, the former two genotypes were relatively more tolerant of extremely low pH than those in the latter group.

“…Several reports have appeared in the literature demonstrating differential AI tolerance among maize (Zea mays L.) genotypes (Foy & Brown, 1964;Lutz, Hawkins & Genter, 1971;Clark & Brown, 1974a;Clark & Brown, 1974b;Konzak, Polle & Kittrick, 1976;Clark, 1977;Rhue & Grogan, 1976;Rhue & Grogan 1977;Stock meyer & Everett, 1978;Stock meyer, Everett & Rhue, 1978;Garcia, Da Silva & Massei, 1979;Rhue, 1979, Naspolini Filho, Bahia Filho, Viana, Gama, Vasconcellos & Magnavaca, 1981Magnavaca, 1983). Although there have been no reports of cultivars having been bred specifically for Al tolerance, the potential of such an approach as a counter to the problems of acid soil infertility is widely recognized (Duvick, Kleese & Frey, 1981;Lafever, 1981).…”

“…Among the indices of performance which have been proposed for various crops are topgrowth and root mass (Foy & Brown, 1964;Lutz et at., 1971;Clark & Brown, 1974a;Clark & Brown, 1974b;Clark, 1977;Magnavaca, 1983), seminal root length (Stockmeyer & Everett, 1978; Stockmeyer et at., Magnavaca, 1983), the difference between seminal root length prior to AI stress and after a period of Al stress (Magnavaca, 1983), the ratio of seminal root length prior to stress to that after stress (Magnavaca, 1983), total root length (Furlani, 1981), and the relative seminal root length of plants grown simultaneously in nutrient solutions with and without Al (Rhue & Grogan, 1976;Rhue & Grogan, 1977;Garcia et 01., 1979;Rhue, 1979).…”
