To study the effects of long-term and short-term high temperature stress recovery on physiological functions appearance quality chrysanthemums, a controlled experiment with chrysanthemums was conducted. The treatments were 25 °C for 3 days (T1D3), 9 (T1D9), 41 (T2D3) 41°C (T2D9). results indicated that there is no significant difference between T1D3 T1D9 groups. Conversely, total chlorophyll ...
hydroponic experiments were performed to exam the dynamic change of endogenous proline in rice seedlings exposed to potassium chromate chromium (vi) or chromium nitrate chromium (iii). although accumulation of both chromium species in rice seedlings was obvious, more chromium was detected in plant tissues of rice seedlings exposed to chromium (iii) than those in chromium (vi), majority being in...
Solid phase microextraction analysis of volatile constituents of heated palm olein and selected oils
Effect of heating on the development of volatile aroma constituents of palm olein and selected oils was studied. The aroma constituents of heated oils were collected using a solid-phase microextraction (SPME) headspace technique with an adsorbent of a divinylbenzene/carboxen (50/ 30μm) on polydimethylsiloxane (PDMS) fibre. The extracted volatiles were desorbed from the fibre in the injection po...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
bioaccumulation and depuration of copper in the kidney and liver of a freshwater fish, capoeta fusca
background: this study aims to investigate the patterns of bioaccumulation and depuration of copper in the selected kidney and liver of capoeta fusca. methods: the fish were collected between september and november 2010 from a qanat in birjand. they were exposed to two types treatments with copper (0.25 and 0.75 mg/l) for a period of 41 days. the fish under study were exposed to the above-menti...

nonylphenol (np) is a well-known compound as having the potential to mimic the natural hormone 17β-estradiol (e2) and disrupt the endocrine system in a wide range of organisms. however, the ability of different isomers of this compound is different in exerting estrogenic effects. the objectives of this study were to estimate the effects of a straight side-chain np isomer (4-n-np) on the vitello...
heavy metal pollution is a worldwide problem with serious environmental consequences. the objective of the present experiment was to investigate whether arginine as nitric oxide precursor and or polyamines substrate can decrease the destructive effects of oxidative stress induced by nickel contamination in hyoscyamus niger plant. in this study the effects of arginine pretreatment on alkaloid co...
