The 2004 Harvest Survey of Canadian canola (1) had higher than average chlorophyll content due to a cooler than normal season combined with an early damaging frost resulting in immature seed. As a result, chlorophyll levels in many No. 1 Canada Canola (1CC) export shipments increased to over 30 mg/kg (2). Dockage has been suspected in contributing to the chlorophyll levels in canola cargoes but...

The current study aimed to ensure the chemical and microbiological quality of imported canned meat. Random samples beef, beef luncheon corned are from different countries were collected local market in Fayoum Governorate.  Chemical composition (moisture, protein, fat, ash content, carbohydrate energy value), Quality indices (pH, Total volatile basic nitrogen Thiobarbituric acid) Microbiological...

The aim of the present study was to investigate effectiveness UV-C treatment using a modified reactor based on Dean vortex flow. Parameters taken into account were total aerobic bacteria count and yeast mould counts, antioxidant capacity, phenolic content, 5-HMF furan formation sensory attributes. A with 68.75 mJ/cm2 led 2.21-log CFU/ml 1.13-log reduction TMAB YM count, respectively. DPPH radic...

The aim of the present study was to evaluate influence NaCl concentration on microflora in Kashkaval cheese produced from cow’s milk. Three samples were obtained - with low (0.7%), medium (1.5%), and standard (3.1%) content NaCl. Microbiological analyses performed 1st, 15 th , 30 45 d ripening. It established that has a significant (p < 0.05) growth activity studied samples. been observed to...

A significant fraction of a plant's nuclear genome encodes chloroplast-targeted proteins, many of which are devoted to the assembly and function of the photosynthetic apparatus. Using digital video imaging of chlorophyll fluorescence, we isolated proton gradient regulation 7 (pgr7) as an Arabidopsis thaliana mutant with low nonphotochemical quenching of chlorophyll fluorescence (NPQ). In pgr7, ...

in order to study the effect of iron chelate (fe-eddha) on some biochemical characteristic of safflower (carthamus tinctorius l.) under two irrigation regimes, a field experiment was set up a split-plot based on randomized block design with four replication in 2011 in a research field of the faculty of agriculture at shahed university. in this study the main plots consisted of two levels of irr...

The preceding paper (2) has described some of the changes that occur in the photosynthetic activity of the mutant strain y-2 of the unicellular green alga Chlamydomonas reinhardi accompanying changes in chlorophyll content. These results indicated that photosynthetic activity might be regulated by a mechanism which is related to either a critical chlorophyll content or structural configuration ...

We present an empirical application of multispectral laser scanning for monitoring the seasonal and spatial changes in pine chlorophyll (a+ b) content and upscaling the accurate leaf-level chlorophyll measurements into branch and tree level. The results show the capability of the new instrument for monitoring the changes in the shape and physiology of tree canopy: the spectral indices retrieved...

determination of chlorophyll content and chlorophyll fluorescence has the potential needed to analyze the efficiency of photosynthesis in plants against environmental stresses, especially salinity, and its simplicity facilitates stress evaluation. in order to study the response of different photosynthetic characters to salinity stress at different sugar beet growth stages, two separate experime...
