Enhancing stress growth traits as well as phytochemical and antioxidant contents of Spiraea and Pittosporum under seaweed extract treatments.
Seaweed extracts (SWE) might play an important role in enhancing growth and phytochemical composition of medicinal shrubs. In this study, we investigate the morphological, physiological and biochemical effects of irrigation levels (100% and 50% of the evapotranspiration rate) coupled with a weekly treatment of SWE of Ascophyllum nodosum at 5 and 7 mL L(-1)… (More)
In vitro antioxidant and antiproliferative activities of six international basil cultivars.
The total phenolic, flavonoid and tannin contents in leaves extracts of Ocimum basilicum (OB) (Lamiaceae) international cultivars, as well as their overall antioxidant activities using DPPH and linoleic acid assays, were investigated. Furthermore, the antiproliferative and cytotoxic activities against line HeLa, MCF-7, Jurkat, HT-29, T24, MIAPaCa-2 cancer… (More)
Transcription profiles of mitochondrial genes correlate with mitochondrial DNA haplotypes in a natural population of Silene vulgaris
BACKGROUND Although rapid changes in copy number and gene order are common within plant mitochondrial genomes, associated patterns of gene transcription are underinvestigated. Previous studies have shown that the gynodioecious plant species Silene vulgaris exhibits high mitochondrial diversity and occasional paternal inheritance of mitochondrial markers.… (More)
Basil morphological and physiological performance under trinexapac-ethyl foliar sprays and prolonged irrigation intervals
Global warming and lack of irrigation water put immense pressure on the production of highly economic and water stress sensitive plants such as Ocimum basilicum which is commonly known as “basil”. The study aims to determine the morphological and physiological effects of trinexapac-ethyl (TE) foliar biweekly sprays with 0.1, 0.2, and 0.3 L ha−1 and/or four… (More)
Egyptian herbal tea infusions' antioxidants and their antiproliferative and cytotoxic activities against cancer cells.
The antioxidant, antiproliferative and cytotoxic activities against different human cancer cells were investigated in local and recently introduced plants of Mentha sp., Rosmarinus officinalis L. (ROL) and Origanum majorana L. (OML). ROL exhibited the highest antioxidant activities (IC50 8.4 ± 0.2 μg/mL) followed by OML and mint species such as Mentha… (More)
Enhancement of Calibrachoa growth, secondary metabolites and bioactivity using seaweed extracts
BACKGROUND Calibrachoa x hybrida (Solanaceae) cultivars are widely used in North and South America as ornamental plants. Their potential as a source of antimicrobial compounds might be enhanced by seaweed extract (SWE) applications. METHODS SWE of Ascophyllum nodosum were applied at 5 and 7 ml/L as a soil drench or foliar spray on Calibrachoa cultivars of… (More)
Chemotyping of diverse Eucalyptus species grown in Egypt and antioxidant and antibacterial activities of its respective essential oils.
The chemical composition of the essential oil from the leaves of Eucalyptus camaldulensis, Eucalyptus camaldulensis var. obtusa and Eucalyptus gomphocephala grown in northern Egypt was analysed by using GC-FID and GC-MS techniques. The antibacterial (agar disc diffusion and minimum inhibitory concentration methods) and antioxidant activities… (More)
In vitro antioxidant, antifungal and antibacterial activities of five international Calibrachoa cultivars.
The total phenolic, flavonoid and tannin contents in leaf extracts of Calibrachoa x hybrida (C.h.) (Solanaceae) international cultivars, as well as their overall antioxidant activities using DPPH and linoleic acid assays, were investigated. Furthermore, the antifungal and the antibacterial activities were examined against a wide spectrum of micro-organisms.… (More)
Growth regulators and mowing heights enhance the morphological and physiological performance of Seaspray turfgrass during drought conditions
With the unusually prolonged drought that results from climate change, increasing the ability of plants to resist drought become a necessity. The objectives of this study were to investigate the effects of two plant growth regulators [(trinexapac-ethyl (TE) and abscisic acid (ABA)], three mowing heights (MH) (25, 35 and 45 mm), and four irrigation levels of… (More)
Medicinal and biological values of Callistemon viminalis extracts: History, current situation and prospects.
Callistemon viminalis (C. viminalis) is a plant that has been reported to have various medicinal values such as antibacterial, antifungal, antioxidant activities and other pharmaceutical and insecticidal properties. This review covers the potentials, applications and properties of different extracts from different parts (branches, flowers, fruits, bark,… (More)
