in order to study the effects of pgpr application methods on proline and soluble sugars content of yarrow (achillea millefolium l.) under drought stress conditionsan experiment was performed at islamic azad university, yadegar-e-imam khomeini (rah) shahre-rey branch. this experiment was carried out in a split plot arrangement with randomized complete block design in three replications. experime...

Greenhouse-cultured, container-grown seedlings of Aleppo pine (Pinus halepensis Mill.), radiata pine (Pinus radiata D. Don), and interior Douglas-fir (Pseudotsuga menziesii var. glauca (Beissn.) Franco) were cold acclimated and deacclimated in growth chambers over 24 weeks. Needle and root cold hardiness and root growth potential (RGP) were measured weekly. Root, needle and stem analyses for so...

This work is a part of a study on the processing of fruit nectars enriched with Aloe vera gel. The aim of this study was to produce therapeutic and high nutritional mango nectar by supplementation of mango pulp with Aloe vera gel. Effects of different addition levels of Aloe vera gel (5, 10, 15, 20 and 25%) on the physical, microbial and chemical properties such as total soluble solids, total a...

Olive leaves are considered to have great potential as natural sources of antioxidants and phenolic compounds. In this study, dried olive were extracted using four different solvents (water, methanol, ethanol, 80:20(v/v) methanol-water) with ultrasonic-assisted extraction. The biochemical (total phenolics flavonoids, total protein, free amino acids, soluble, reducing sugars) antioxidant activit...

Black currant berries contain many biochemical compounds with proven or potential human health benefits. We studied the content of total and single polyphenols, ascorbic acid, soluble sugars, and titratable acidity for two advanced selections and three cultivars of black currant at two distant locations in Sweden (south: 56°06'N; north: 65°21'N) over a 3 year period. Regression analyses reveale...

The relationships between rooting potential with endogenous phenolic compounds, nitrogen and soluble carbohydrates of cuttings for five olive cultivars (‘Rowghani’, ‘Dusti’, ‘Tokhmekabki’, ‘Konservalia’ and ‘Amigdalolia’) were investigated. Extracts of the leaves and the base of the cuttings were used for analysis of biochemical compounds. Results showed that there were significant differences ...

abstract background and objectives: soil salinity is one of the most important limited factors of plant productions. physiological drought resulting from salinity stress is one of the main reasons of limiting water absorption from soil. moreover, increasing the salt absorption by plants cause to disorder in physiological and cellular processes. spearmint (mentha spicata l.) is from lamiaceae fa...

Two-year-old seedlings of Picea abies L., P. glauca L., P. mciriana L., Pinus sylvestris L. and Pseudotsuga menziesii L. were planted in a sample plot influenced by high concentrations of cement dust, and in an unpolluted (control) area in 1990. In 1994, the six-year-old trees were dug up in the pre-bud-break period. A comparative analysis of soluble sugars (glucose, fruc­ tose, sucrose, maltod...
