To study the structure-activity relationship of mugineic acid (MA), a phytosiderophore isolated from Hordeum velugare L. var. Minorimugi, several 2-deoxymugineic acid (DMA) analogues were synthesized. 1H-NMR spectra of DMA analogues and their Co(III) complexes were first measured and analyzed to elucidate the structures of metal complexes. CD spectra of the Co(III) and Fe(III) complexes of DMA ...

demographic parameters of the pink stem borer, sesamia creticalederer (lepidoptera: noctuidae) were estimatedon its two main host plants, maize and sugarcane. the present studywas conducted under laboratory conditions at 27±1˚c, 50±10% relative humidity (rh %), and a photoperiod of 0:24 (l:d) hour for the larval stage and 16:8 (l:d) hour for the other life stages. the raw data were analyzed bas...

Cadmium (Cd) pollution of agricultural soils is a growing global concern. Plant growth restriction the main visible symptom Cd toxicity, and this metal may be particularly harmful to preformed, seminal root during pre-emergence stage. In present study, we focused on phytotoxicity in growth, nutrient composition, redox status, hormone homeostasis stage maize (Zea mays L) plants, distinguishing b...
