introduction   heavy metal contamination has disastrous effects on plant productivity and threatens human and animal health. among metals, cadmium (cd) is commonly released into the environment from industrial processes. cd is known to cause cellular damage in plants by producing oxidative stress via the over-production of reactive oxygen species (ros). to combat oxidative damage, plants have d...

Sisal leaves which constitute only 2% of the sisal plant have been used in the production of pulp and fiber; the remaining 98% which is mostly of the sisal bole is largely regarded as waste. The bole’s high inulin fraction (2436%) is of particular significance due to its chemical functionality and relative ease of fermentation. utilisationThe objective of this study was to identify properties a...

Few studies have investigated the alkali-based salt resistance aspect of plants. Here, we used 2 pumpkin cultivars (‘Cucurbita ficifolia Bouch.’ and ‘Chuandilong’) to study the growth and physiological response mechanisms of pumpkin to different levels of NaHCO3 stress. After second true leaf development, pumpkin seedlings were treated with varying levels of NaHCO3 stress (0, 30, 60 and 90 mmol...

To understand the physiological mechanism by which soybean (cultivar: Glycine max L. Merr. cv.JH13) regulates its growth in response to drought under elevated CO 2 concentration, a pot experiment with two levels of CO 2 (350 vs. 700 μmol·mol) and two levels of water (well irrigated vs. drought) was conducted. Plant relative growth rate (RGR), water potential (WP), photosynthetic pigment (chloro...

AIMS The objective of this study was to determine the effect of increasing juice soluble solids above 40 degrees Brix on wine yeast's ability to grow and ferment the juice, with particular focus on acetic acid production, titratable acidity (TA) changes and the maximum amount of sugar consumed by the yeast. METHODS AND RESULTS Riesling Icewine juices at 40, 42, 44 and 46 degrees Brix were ino...

in this research, the effect of using vermicompost on growth rate, fertility and characteristics oftomatoes has been studied. four vermicompost: soil mixture were supplied with ratios of 1:1, 1:2, 1:3, and 1:4 and also four different beds were provided. total of 24 small globe tomato plants were tested and in each bed combination, six tomato plants were embedded. rate of growth and yielding of ...

To explore the function of light-harvesting complex protein (LHCP) in Arabidopsis growth and development, the Leclere and Bartel seed collection was screened. In this collection randomly cloned cDNAs are expressed under the CaMV35S promoter. A pale green line has been identified and characterized in more details. Analysis of the inserted cDNA in the pale green line showed it encodes LHCB1 prote...

We evaluated in vitro the cariogenic and erosive potential of antitussive liquid oral medications for paediatric use. Fifteen paediatric liquid antitussives were sampled. The endogenous pH was evaluated by potentiometry, titratable acidity was measured according to the method adopted by the Association of Official Analytical Chemists, total soluble solids content (TSSC) readings were performed ...

Wheat leaf non-sequential senescence at the late grain-filling stage involves the early senescence of younger flag leaves compared to that observed in older second leaves. On the other hand, sequential senescence involves leaf senescence that follows an age-related pattern, in which flag leaves are the latest to undergo senescence. The characteristics of sugar metabolism in two sequential senes...

Five soluble polysaccharide fractions were sequentially extracted with water, EDTA, Na2CO3, 4% KOH, and 14% KOH solutions at room temperature for 4 h from cell wall material of rabbiteye blueberry (Vaccinium ashei) fruits, and their physicochemical properties were examined. The sequential treatments yielded a total 36.02% soluble polysaccharides of the dry cell wall material. HPAEC and spectros...
