Clonal propagation techniques are required for Prosopis due to great variability in biomass productivity, pod productivity, and nitrogen fixation from seed propagated stock. Previous studies identified a decline in the rooting percentage of cuttings taken from stock plants that were grown in the growth chamber and harvested every four weeks. To determine the influence of the mineral nutrient status of the stock plants on the rooting of cuttings, fertilized and nonfertilized Prosopis alba clone B2B50 stock plants were established under 1000 W metal halide lamps in the greenhouse. A complete macro- and micronutrient solution was used. The regrowth was harvested after 4, 8, 12, 16, and 20 weeks, and alternate nodes from each stem were taken for the rooting assay and for N, P, K. Ca, Mg, Fe, Zn an total available carbohydrate evaluation (N=79). The mean rooting percentage for the five harvest cycles was 58% for the fertilized stock plants, and 44% for the nonfertilized stock plants (P=0.087). There was no significant correlation between rooting percentage and leaf carbohydrate (P=0.964), stem carbohydrate (P=0.876) and leaf plus stem phosphorus (P=0.319). The monsignificant correlation between percent rooting and carbohydrates was negative (r=-0.018). However, there was a significant correlation with stem nitrogen and percent rooting (P=0.009) and inverse correlation between sten nitrogen and leaf carbohydrate content (r=-0.353, P=0.001).

There is an urgent need for improvements in animal production, particularly for ruminants, such that more sustainable and efficient processes are developed for obtaining more nutritious and efficient feeds. Filamentous fungi can add value to residual plant biomass, and may also have the potential to produce metabolites and enrich plant biomasses used in animal nutrition, converting them into nutraceutical sources. Thus, in this work, filamentous fungal fermentation of ruminant feed biomasses commonly used in Brazil was performed, and the enrichment for bioactive metabolites was tested. For this, Fistulina hepatica, Ganoderma lucidum, Pleurotus pulmonarius, Panus lecomtei, and Aspergillus terreus were grown for 28 days on different substrates: starchy grains- (sorghum, oat, and corn), fibrous substrates (coast-cross, rice husk, and moringa plant) and protein-rich substrates (cottonseed cake and pigeon pea plant). Fermented substrates were evaluated for laccase activity, crude protein, -glucan, and lovastatin content. |
