Zinc (Zn) deficiency is occurring in different climate regions and almost all countries. a common micronutrient plants causes severe reductions crop production. In this study the effect of zinc on pigment content peroxidase activity early growth phase tomato seedlings was investigated. For purpose, Hoagland solutions with or without (ZnCl 2 ) were used as medium to determine possible effects deficiency. order elucidate physiological consequences deficiency; anthocyanin, carotenoid,...
In this study, the phytoremediation capacity of Azolla filiculoides Lam. for water resources contaminated with petroleum hydrocarbons was investigated. The plants were grown in nitrogen-free Hoagland nutrient solution containing 0.005%, 0.01%, 0.05%, 0.1%, 0.2%, 0.3%, 0.4%, and 0.5% crude oil under greenhouse conditions 15 days. Although growth rate not negatively influenced by presence media concentration 0.005% 0.01% v/v, a gradual impeding effect has been observed at concentrations...
This study aimed to evaluate the growth performance, pigment content changes, essential amino acids (EAAs), fatty (FAs), and proximate composition of Azolla pinnata caroliniana grown in a greenhouse. Plants were nitrogen-free Hoagland?s solution at 28?2?C/21?2?C, day/night temperature 60-70% humidity examined on 3rd, 5th, 10th 15th days. The mean percentage plant relative rate for A. 119% 0.148 gg-1day-1, respectively, while these values 94% 0.120 respectively. Compared day 3, amount total...
Abstract Azolla is a floating fern, which contains the nitrogen-fixing cyanobacterium Anabaena azollae in dorsal lobe cavity of leaves. This study investigated effects seasonal changes on pigment composition filiculoides small pond located Istanbul, Turkey. Sampling was conducted March, April, May, October, November, December 2007. The average total chlorophyll and carotenoid content leaves almost half fold lower March-April-May than October-November-December. For late winter–spring, while...
This study aimed to determine the volatile profile by GC-MS and antimicrobial activity of essential oil isolated from Thymus nummularius using microwave-assisted hydrodistillation method morphologically characterize glandular trichomes in leaf samples. Obtained oil, as well wastewater obtained during isolation, were chemically (polyphenolic compounds, organic acids, total phenolic content, flavonoid content antioxidant activity) characterized. As a result analysis different ratios components...
In this study, the potential of Landoltia punctata for petroleum phytoremediation was evaluated. L. treated with different concentrations Batman crude oil (BCO). The plants were grown in nutrient solutions containing 0.5%, 1%, 2%, and 3% BCO by volume a growth chamber 7 days. fresh weight presence at concentration 0.5% v/v increased 60% relative to initial weight. Furthermore, comparison control, plant retarded 72% 91% 2% 3%, respectively. When media BCO, more than 90% C_{15}-C_{25} n-alkane...
Phytoremediation of freshwater contaminated with crude oil is a technology that can restore damaged areas. Lemna minor small vascular plant reproduces rapidly, sensitive to wide variety pollutants, and easy culture. This study aimed evaluate the phytoremediation capacity L. in spiked cultures. Cultivation was carried out for 7 days greenhouse natural photoperiod nutrient solutions containing 0.5%, 1%, 2%, 3% oil. Extracts were analyzed using GC/MS synchronous UV fluorescence spectroscopy....
In this study, the potential of Azolla filiculoides, a freshwater fern species, on phenanthrene phytoremediation and biodegradation was investigated. Furthermore, effect growth performance, photosynthetic activity biosynthesis, accumulation secondary metabolites A. filiculodes were evaluated. Plants grown in nitrogen-free Hoagland exposed to different concentrations (0, 1, 5, 10 mg/L). Exposure mg/L caused significant reduction (42%) filiculoides compared control day 14. The pigment content...
Primula vulgaris L. (Primrose) of Primulaceae family is an annual or perennial herbaceous ornamental plant with white, yellow, pink, red violet flowers. There no study on the relationship between various pigments and petal colors this plant, which has important place in urban architecture, resistant to cold weather, grows scattered clumps, leaves flowers are clustered form a rosette at base. This aims inspect anthocyanin, P. employed as material chlorophyll. It further determining whether...
Acetic acid (AA) is an organic and has been widely used as food preservative a dietary spice in vinegar form. In addition to its therapeutic uses form, AA attenuates inhibitory effects of stress plants. However, some plant species toxic have found. Therefore, this study, 0, 2.5 5 mM concentrations were applied 2-day-old barley ( Hordeum vulgare L. cv. Bornova-92) seedlings for 2 days order investigate the possible AA. After treatments, grown AA-free conditions recover. inhibited root shoot...
The present study examined the naphthalene stress responses of aquatic fern Azolla filiculoides Lam. and evaluated its phytoremediation potential. A. were grown in nitrogen (N)-free Hoagland containing 25, 50, 75 mg L−1 greenhouse. At mgL−1 concentration, percentage plant growth relative rates 118% 0,09 gg−1d−1 respectively. Photosynthetic pigment contents increased parallel with increasing concentrations on third day. In naphthalene, flavonoid phenolic as secondary metabolites compared to...
Phytoremediation which is defined as cleaning of the contaminated soil, water and air a result human activities by using plants, an environmentally friendly alternative technology to be promising. The removal organic pollutants accumulated in organisms habitat’s environmental pollution, has great importance because their toxic, mutagen carcinogen structures. Depending on chemical properties may degraded rhizosphere or taken up then degradation plant cells sequestrated with conjugation vacuol...
