Abstract

The objectives of this experiment was to evaluate the effect of drought stress and defoliation interval on shoot and root morphologic characteristic of Indigofera zollingeriana. The experiment was arranged in a completely randomized design with two factors and four replications. The first factor consisted of 3 level of drought stress i.e: 100% field capacity (FC) (control), 50% FC, and 25% FC. The second factor comprised of 3 defoliation interval were interval defoliations of 60, 90 and 120 days. The observed variables were shoot, root dry weight, root/shoot ratio and root length. Data were analyzed by ANOVA and the differences between treatments were tested by LSD. The results shows that there were interactions (P < 0,05) between drought stress and defoliations interval on shoot dry weight, while root dry weight, root/shoot ratio, and root length was not. Drought treatment significantly (P < 0,05) decreased shoot, root dry weight, but increase of root/shoot ratio and root length. Defoliation interval significantly affected (P < 0,05) on shoot dry weight, but not on root dry weight, root/shoot ratio, and root length.

Abstract

Abstract. The objective of this research was to study the isolation and effect of Al-tolerant phosphate solubilizing microorganisms to growth, production of grasses and phosphate dissolution mechanism. The planting materials used were S. splendida and C. gayana pols. The treatment consisted of four selected isolates, namely Po = without phosphate solubilizing bacteria(PSB), P1 = RJM.30.2, P2 = FT.3.2, P3 = FT.3.4, P4 = B8016495, P5 = B8016498, P6 = the mixture from four isolates P2-P5. Observed variables were pH, shoot and root dry weight, and P absorption.  The best phosphate solubilizing microorganism on acid soil were FP.3.2, FP.3.3, B8016495 and B8016498. Phosphate solubilizing microorganism could not yet increase shoot and root dry weight production on grasses S. splendida and C. gayana, but had shown increasing P shoot and root content and  P uptake. On grass S. splendida the best isolate to increase P shoot and root of shoot and root, organic acid. The best phosphate solubilizing microorganism on acid soil content and P uptake was FT.3.3.  On grass C gayana the best isolate to increase P shoot and root content and P uptake were RJM.30.2. and FT.3.3.  Organic acid exudated by FT.3.3. were oxalic  and acetic acid as phosphate dissolution mechanism. Keywords: phosphate solubilizing microorganism, acid soil, forage grasses, Setaria splendida, Chloris gayanaAnimal Production 14(1):13-22, January 2012

Abstract

The objective of this experiment was to evaluate the effect of drought stress and mycorrhizal inoculation on physiological adaptation and biomass production of Macroptilium bracteatum. This experiment was arranged in completely randomized design with four treatments: M0 (no AM + watered), M1 (AM + watered), M2 (no AM + drought), and M3 (AM + drought) with three replicates. The observed variables were soil water content, leaf water potential, leaf relative water content, leaf proline, leaf water soluble carbohydrate (WSC), root and shoot dry weight. Data were analyzed by ANOVA and differences between treatments were tested by DMRT. Drought treatments (M2 and M3) significantly (P < 0.05) decrease soil water content, leaf water potential, leaf relative water content and increased the leaf proline content. The result in root and shoot dry weight appear that M1 treatment was significantly different (P < 0.05) with treatment M0, M2, and M3. For leaf WSC, M0 and M2 treatments were significantly different (P < 0.05) with treatment M1 and M3. It is concluded that mycorrhiza inoculation was more effective on M. bracteatum, in drought stress. One mechanism of drought resistance of M. bracteatum is the accumulation of osmotic compounds proline. Therefore, proline can be used as an indicator of drought resistance in leguminous plants.
