“…The reduction in leaf number and size was observed in pigeonpea seedlings only at very high concentrations of 40 and 60 ppm Al. Dessureaux (1969) reported that at 20 ppm, the leaf size was significantly reduced in alfalfa seedlings. The tap root length was considerably restricted at 40 ppm Al, whereas at 10 ppm level, there was a stimulation of root length.…”

With 5 figures and 5 tables Abstract Aluminium (Al) tolerance of 60 genotypes was evaluated using the growth response and haematoxylin staining methods. Major traits used to evaluate Al tolerance were score of root staining, root regrowth after staining, root and shoot length, dry weight of roots and shoots, and pods/plant. Significant variability was noted for tolerance to Al toxicity among the lentil genotypes for all traits except score of root staining. Score of haematoxylin root staining did not show any correlation with growth response method. However, root regrowth after staining showed significant correlation with root and shoot length, dry weight of roots and shoots, and pods/plant. In a further long‐term experiment, the Al tolerance of three tolerant (‘L‐7903’, ‘L‐4602’ and ‘ILL‐6002’) and two sensitive (‘L‐4147’ and ‘BARI Massor‐4’) lines was assessed at the adult stage to evaluate the consistency of Al tolerance. This study also showed that Al tolerance of lentil does not vary with plant growth stage, so selection for increased Al tolerance can be carried out at the seedling growth stage.

“…Likewise, Loneragan et al (29) and Loneragan and Snowball (28) have reported an increase in Ca concentration in tops of several legumes and grass species with an increase in solution Ca concentrations upto 1.00 mM.Effects of Al: The concentrations of Al in soil solutions for a number of acid temperate soils (9) and acid tropical soils(7) have been reported to vary from 14 to 96 and 2 to 101 /j,M, respectively. However, some researchers(8,27) in the past have employed extremely high Al concentrations (in the range of 1180 -3700 JUM) in nutrient solutions used for investigations on the effects of Al Downloaded by [University of Montana] at 19:12 05 April 2015 toxicity on plant response. These unrealistically high Al concentrations cause severe injury to plant roots resulting in loss of selectivity.…”

Investigations on the effects of acid soil infertility factors on legumes are often focussed on growth, nodulation, and N 2 -fixation, while very little emphasis has been given to the mineral composition of plants. In the present investigation, effects of varying solution pH [4.5, 5.0 and 5.5], concentrations of Ca [0.05, 0.5 and 2.5 mM] and activities of Al [0 -33 μM] on chemical composition of the tops of soybean [Glycine max (L.) Merr. cv. Fitzroy] and cowpea [Vigna unguiculata (L.) Walp. cv. Vita 4] plants grown in dilute nutrient solutions were examined. An increase in solution pH significantly increased concentrations of N, K, Ca, Mn, and Zn in soybean tops and concentrations of only K and Mn in cowpea tops. An increase in solution Ca concentration increased concentrations of Ca and Cu, and decreased concentrations of Mg, Mn, and Zn in both soybean and cowpea tops. The concentration of Al in soybean and cowpea tops was greater in plants grown in solutions containing a sum of activities of monomeric Al species [Σa Al mono ] of 6.5 ΜM than that in plants grown in solutions containing no Al. Further increase in Σa Al mono in solutions decreased Al concentration in soybean tops, but not in cowpea tops. An increase in Σa A1 mono in solutions decreased the concentrations of N, P, K, Ca, Mg, Mn, Zn and Cu in soybean and cowpea tops. However, the Σa Al mono at which concentrations of each of the essential elements in plant tops decreased significantly were different for soybean and cowpea.
