the effect of four citrus rootstocks {sour orange (citrus aurantium), bakraeii (c. reticulata × c. limetta, mexican lime (c. aurantifolia) and volkamerlemon (c. volkameriana)} were evaluated on sweet lime leaf chlorophyll content and mineral concentrations (n, p, k, ca, na, mg, fe, zn, mn, cl, cu, and b) in a completely randomized design of four replications. budded sweet lime on the above root...

in this study, the effect of four citrus rootstocks {sour orange (citrus aurantium), bakraeii (c. reticulata × c. aurantium, mexican lime (c. aurantifolia) and volkamerlemon (c. volkameriana)} on orlando tangelo leaf chlorophyll content and mineral element concentrations (n, p, k, ca, na, mg, fe, zn, mn, cl, cu, and b) have been evaluated in completely randomized design with four replications. ...

Soybean (Glycine max [L.] Merr. var. Glabrous D62-7812) plants were grown in aerated Hoagland and Arnon mineral nutrient solution containing 0 or 2.6 mum S-ethyl dipropylthiocarbamate (EPTC) in a growth chamber. After 19 days exposure to EPTC, total leaf fresh weight was reduced 18% by 2.6 mum EPTC while total leaf fatty acid content was reduced 63%. Galactolipid content decreased while phospho...

Tobacco plants (Nicotiana rustica L.) pre-exposed to leaf dehydration, mineral deprivation, salination, or BO(3) (3-) toxicity exhibited increased resistance to subzero temperature and to reduced oxygen in the root medium. The stressed plants all showed an elevated content of leaf abscisic acid. Upon transfer of mineral deprived and salinated plants to prestress conditions, a decline in leaf ab...

‘Ogi’ was produced from yellow variety of maize to obtain a fermented gruel from ogi and the effect of moringa leaves fortification on the nutritional value and the sensory properties of yellow maize-ogi was investigated. The moringa leaf powder was substituted into yellow maize-ogi in these formulations; 100:0, 90:10 and 85:15. The effects of the moringa leaves powder substitution on the proxi...

The objective of this work was to evaluate the effects of potassium (K) fertilization on vegetative growth, fruit production and leaf mineral content of olive tree (Olea europeae L.) under rainfed condition. Different fertilizer, techniques and rates of application were applied in 2003 on Chemlali olive. The potassium fertilizer used was potassium nitrate. The foliar fertilizer rates were 50 an...

AIM This study was designed to determine the proximate composition and mineral content of Costus afer leaf and stem, as well as to identify the most active antioxidant fraction. MATERIALS AND METHODS The proximate composition and mineral analysis of C. afer leaf and stem were performed using the standard methods described by Pearson and Association of Official Analytical Chemist while the 1,1...

This study was carried out during 2004 and 2005 seasons on eight years old Arabi pomegranate trees grown in sandy soil to investigate the influence of microbial biofertilization on tree growth, yield, fruit quality and leaf minerals content. Microbial inoculum (Azotobacter spp. Azospirillum spp. and Bacillus megatherium which found in (Biogein, Nitrobine, phosphorein), in addition, arbuscular m...

Enhancing nutrient density in legume seeds is one of several strategies being explored to improve the nutritional quality of the food supply. In order to develop crop varieties with increased seed mineral concentration, a more detailed understanding of mineral translocation within the plant is required. By studying mineral accumulation in different organs within genetically diverse members of t...

Heavy atmospheric nitrogen (N) deposition has been associated with altered nutrient cycling, and even N saturation, in forest ecosystems previously thought to be N-limited. This observation has prompted application to such forests of non-N mineral nutrients as a mitigation measure. We examined leaf gas-exchange, leaf chemistry and leaf and shoot morphological responses of Acer saccharum Marsh. ...
