Effect of different NaCl levels in nutrient solution on the Pennisetum spp. genotypes

    The aim of this research was to evaluate the effect of three NaCl levels in nutrient solution on initial development and regrowth of nine Pennisetum spp. genotypes. The experiment was carried out in greenhouse conditions, using a completely randomized design, distributed in a 9 × 3 factorial arrangement [nine Pennisetum spp. genotypes (Cameroon,...

Combining ability and heterosis for aluminium stress tolerance of soybean roots and shoots grown in acid sand culture

  A six parent F2 diallel of soybeans was evaluated in potted acid sand culture with the objective of estimating combining ability and heterosis for aluminium stress tolerance. Highly significant differences were observed among the genotypes, crosses (F2/R), Parents, F2, Reciprocals (R) and Parents Vs (F2/R) for the root dry weight, shoot dry weight and relative root surface area. Both general combining...
