The effects of soil inoculation with phosphoriencontaining phosphate-dissolving bacteria (PDB) and/or magnesium (Mg) foliar application at the rates of 0, 0.5 and 1mM on growth, green pod and seed yields, and chemical constituents of Pisum sativum L. grown on a sandy calcareous soil were investigated. Results indicated that PDB and/or Mg significantly increased shoot length, number of branches ...

                The present study was undertaken to evaluate direct and indirect selection criteria for the improvement of grain yield and quality components in Chenopodium quinoa Willd. Correlated response (CR) and relative selection efficiency (RSE) were estimated for grain yield and three quality components, grain protein, grain carotenoid and leaf carotenoid based on different contributing ...

I. Digestion of grass lipids and pigments in the rumen of the sheep has been studied during starvation and following the administration of "C-labelled grass. 2. Both galactolipids contained in chloroplasts are rapidly degraded, although mono-galactos~ldiglycerides disappear faster than digalactosyldiglycerides. I t was concluded that rumen microorganisms are mainly responsible for this degradat...

transgenic and non transgenic nicotiana tabacum l (cultivar wisconsin) containing ri t-dna were treated with 0, 0.2 and 0.4 mgl-1 ga3 in murashig and skoog medium. some physiological parameters including shoot length, leaf area, number of auxiliary bud, fresh and dry weight, number and length of trichomes were measured. shoot length, fresh weight and dry weight were increased but number of tric...

The effect of a colloidal solution of Cu,Zn-nanoparticles on pro-oxidative/antioxidative balance and content of photosynthetic pigments and leaf area of winter wheat plants of steppe (Acveduc) and forest-steppe (Stolichna) ecotypes was investigated in drought conditions. It has been shown that Cu,Zn-nanoparticles decreased the negative effect of drought action upon plants of steppe ecotype Acve...

The main objective of this study was to examine the effects of NaCl on the leaf growth and some physiological and biochemical characteristics of an Algerian durum wheat (var. Waha) landrace. NaCl (150 mM), as compared to control plants, significantly reduced all the leaf-growth parameters as leaf area (33%), leaf dry weight (41%) and leaf fresh weight (32%), but did not induce any change in the...

The conifer leaf model LIBERTY (Leaf Incorporating erties of individual leaves (Aber, 1994). Leaves are an Biochemistry Exhibiting Ref lectance and Transmittance important component of forest canopies, and it is the Yields) is an adaptation of radiative transfer theory for deconcentration of their biochemical constituents, namely, termining the optical properties of powders. LIBERTY pigments, w...

The occurrence of fringed wings insect, Pseudodendrothrips mori is a major pest of mulberry, which causes a considerable leaf yield loss and inturn damages its quality. Hence, an attempt was made to know the changes in biochemical constituents (Free amino acids, total soluble proteins, total reducing sugars, total soluble sugars, starch and total phenols) and photosynthetic pigments (total chlo...

I. Abstract The level of photosynthetic activity as determined by the presence of starch stores was measured for pigmented leaves of seven plant species. The plants were exposed to morning sunlight, then the leaves were picked and pigments extracted by boiling the leaves in an 80% ethyl alcohol solution. A potassium iodide solution was used to stain the starch stores dark blue, and the levels o...

The photosynthesis in evergreen trees living in Mediterranean ecosystems is subjected to multiple climatic stresses due to water shortage and high temperatures during the summer and to low temperatures during the winter. Mediterranean perennials deploy different photoprotective mechanisms to prevent damage to the photosynthetic system. Wax accumulation in leaves is a primary response which by e...
