Abstract Background and Aims To sustainably manage N in oil palm systems quantities of fixed by cover legumes need to be understood. Current values are scarce, based on shoot measures do not include litter which releases nitrate as it decomposes. We aimed quantify 2 under PNG determine if soil influenced dependence fixation (Ndfa). Methods The ureide technique for estimating tropical legume Ndf...

The essential oils obtained by hydrodistillation from the different parts (inflorescence, stalk leaves, rosette leaves and root) as well as from in vitro shoot culture of Eryngium planum L. were analyzed by GC-FID-MS in respect to their chemical composition. The different parts of E. planum and in vitro shoots showed different yields. The part with higher amount was the inflorescences, followed...

Short-term salt (NaCl) treatment on Aegiceras corniculatum in roots and leaves showed no change in fresh and dry weight of leaves, roots and leaf area. There was no significant change in total soluble root protein, photosynthetic pigments of leaves and spectral characteristics of thylakoids. However, the activity of antioxidative enzymes (catalase, ascorbate peroxidase and guaiacol peroxidase) ...

In this study, Eryngium billardieri was collected from Patnos district of Ağrı province during the vegetation period. While some plant stored fresh in a -86oC freezer, other part preserved as herbarium material. After species were identified, methanol and pure water extracts prepared aerial parts samples. The phenolic contents determined by using HPLC. Moreover, various vitro antioxidant proper...
