in order to investigate the effect of mycorrhizal fungi and phosphorus fertilizer on concentration of leaf nutrients and photosynthetic pigments of bean (phaseolus vulgaris l.) in condition of irrigation with saline water, an experiment was conducted based on completely randomized design with three replications in greenhouse of bahonar university of kerman, iran during 2010. the studied factors...

Photosynthetic effects of the leaves extracts from Ipomoea cairica on Parthenium hysterophorus L were studied. Ipomoea cairica dried leaf powder (20g) was dissolved in distilled water (200ml) for foliar application. The seedlings were maintained under natural condition in Insect free net house. The experiment was carried out to analyze the effects of Ipomoea cairica leaves extract by measuring ...

Sunlight is the most abundant energy source on this planet. However, the ability to convert sunlight into biological energy in the form of adenosine-5'-triphosphate (ATP) is thought to be limited to chlorophyll-containing chloroplasts in photosynthetic organisms. Here we show that mammalian mitochondria can also capture light and synthesize ATP when mixed with a light-capturing metabolite of ch...

cadmium as a heavy metal is also considered as a serious threat for the environment. this element is accumulated in soil through industrial processes as well as phosphate fertilizers and aggregates into the food chain.this study was conducted in order to investigate of different levels of cadmium effects on growth features of rapeseed(brassica napus l.) plants. root and shoot weight and height,...

Action spectra of the Emerson effect in Chlorella and Navicula reveal peaks at 670 mut, in addition to those at 650 mu (Chlorella) and 630 mmicro (Navicula) attributable to chlorophylls b and c. Thus, excitation of chlorophyll a form "chlorophyll a 670" can supplement, in these algae, the excitation of the form "chlorophyll a 680-700." The effect of the auxiliary pigments in these algae may be ...

nitrate and ammonium ions are the two major forms of nitrogen that taken up by plants, but they differ in their effects on growth and chemical composition of biochemical levels. in this research we examined the effect of nitrogen sources on growth and senescence of rice leaves in biochemical levels. our results showed that amounts of fresh and dry weights, total chlorophyll, rate of hill,s reac...

Maillard Reaction Products (MRP) was prepared from glucose and glysine heated at 90 ̊C in air circulating oven for 12 hours. The effect of MRP on chlorophyll stability in green peas was investigated. The addition of Maillard Reaction Products (MRP) decreased the loss of chlorophyll a, chlorophyll b and total chlorophyll. The conversion of pheophytin and pyropheophytin was also reduced by the add...

to evaluate and compare the chlorophyll content, carotenoid, protein, peroxidase and polyphenol oxidase in different barley species in iran, 49 genotypes belonging to 5 barley species were employed in a completely randomized design with three replications in greenhouse conditions. a high level of within and between species variation was detected. in all the species, significant positive correla...
