“…The strawberry fruit (Fragaria × ananassa Duch) is one of the most popular berry fruits due to its taste quality and nutritional values (Khan et al 2010). From an economic point of view, strawberries are the most important soft fruits cultivated in the world, mainly in the northern hemisphere, in the temperate climate zone (Hummer and Hancock 2009).…”

Due to the impoverishment of agricultural and horticultural soils and replant diseases, there is a need to use bioproducts and beneficial microorganisms in order to improve the quality of soils and growth substrates. For this reason, research was undertaken to assess the impact of arbuscular mycorrhizal fungi and rhizosphere bacteria on changes in soil microbiology, the degree of colonization of plant roots by mycorrhizal fungi, selected physiological parameters, and fruit quality and yield of the strawberry cultivar "Rumba." The plants were inoculated with the mycorrhizal preparation Mykoflor (Rhizophagus irregularis, Funneliformis mosseae, Claroideoglomus etunicatum), MYC 800 (Rhizophagus intraradices), and the bacterial preparation Rhizocell C (Bacillus amyloliquefaciens IT45). The applied preparations increased the total number of bacteria and fungi in the soil and mycorrhizal frequency in the roots of the strawberry plants. They increased the chlorophyll "a" and total chlorophyll concentrations in the leaves as well as the rate of transpiration and CO 2 concentration in the intercellular spaces in the leaves. The plants treated with Rhizocell C and MYC 800 exhibited a higher CO 2 assimilation rate than control plants. The biopreparations increased chlorophyll fluorescence parameters such as maximum fluorescence (F M) and the maximum potential photochemical reaction efficiency in PS II (F V /F M). The influence of the species of rhizosphere bacteria and mycorrhizal fungi used in the experiment on the physiological traits of strawberry plants contributed, especially in the second year of the study, to increase the yield and mean weight of strawberry fruit.

“…The samples were then maintained at 500 °C for 10 minutes. To determine the ash content, the furnace temperature was increased again to a constant temperature of 750 °C with the same ramp rate in an air flux of 20 ml min −1 [10,11]. The results of thermal analysis for water content, and ash were reported on constant weight basis, while the results of volatile matter were estimated by fixed time method.…”

“…For volatile measurement, the temperature of the furnace was increased with a ramp rate of 16 °C min -1 . The amount of volatile matter was estimated after a constant heating at 950 °C for 7 minutes in a nitrogen environment to ensure complete devolatilisation [10,11]. The samples were then maintained at 500 °C for 10 minutes.…”

The nutritional composition of Ficus carica commonly known as fig is of great interest as it is considered a good source of energy and minerals. Seven samples of fig, cultivated in Pakistan were studied for their physico-chemical properties. All samples had little moisture, less amounts of ash and high volatile matters. Low moisture is favorable in preventing the fermentation of the fruit while high volatiles are responsible for its unique taste. The energy content of the samples ranged between 337.60 -364.70 kcal/100g. The samples were found to be a good source of potassium (3.82-6.11 g/kg), magnesium (0.11-0.20 g/kg), calcium (78.72-132.80 mg/kg) and sodium (5.58-17.69 mg/kg). The mineral and trace contents of the indigenous samples were compared with the samples cultivated in the USA, Turkey and Iran. The samples cultivated in Pakistan were found to have good nutritional values especially higher calorific value and iron content compared to the reported data. The Ca/P ratio in the indigenous variety lies as recommended by nutritionists. This feature made the indigenous variety distinct as the patients suffering from stone formation in kidney may also use it safely. The high potassium in fig is beneficial not only to patients of hypertension but also prevents the bones from rapid thinning by neutralizing the increased urinary calcium loss. Significant correlations were found between iron and potassium, copper and potassium and zinc and copper (p<0.05). The positive correlations are either due to higher uptake of metals by the plant or the excess availability of the metals in the soil. Analysis of means (ANOM) was applied to evaluate the compositional variations between the samples. The study provides an overview of the physico-chemical properties of fig samples indigenous to Pakistan. The results offer useful information not only to consumers who want to buy the best quality fruit, but also to producers interested in increasing the competitiveness of fig cultivation.

“…The high moisture content has been implicated for the susceptibility and vulnerability of the fruits to spoilage if not properly stored due to the increasing microbial action. [28]. High moisture content in fruits reduces the shelflife of fruits by enhancing microbial growth on the fruits while low moisture content prevents the microbial growth thereby elongating the shelf-life of the fruits.…”

Carissa edulis Vahl (Apocynaceae) is a plant whose leaves, roots and fruits are traditionally employed for the treatment of malaria, microbial infections, headache, cough, fever and ulcer among many others. Fresh fruits of Carissa edulis were crushed and extracted with 70 % methanol for 72 hours to obtain MeOH extract. Proximate analysis as well as mineral composition of the fresh fruits were determined. Total phenolic content (TPC), total flavonoids content (TFC) and antioxidant activity (DPPH, FRAP & Ferrous chelating) of the MeOH extract were determined, while the α-glucosidase inhibitory activity of the extract was conducted using bioautographic assay. The structure of compounds isolated were elucidated by 1D NMR spectroscopic analysis and high-resolution mass spectrometric (HRESIMS) data. The results showed that the nutritive value of the fresh Carissa edulis is 43.43 kcal/100 g, while the extract demonstrated good antioxidant activities (DPPH, IC50 = 87.98 μg/ml; FRAP, EC50 = 464.33 μg/ml & Ferrous chelating, EC50 = 294.55 μg/ml). Further study of the MeOH extract of the fruit led to the isolation of rhamnetin-3-β-D-glucopyranoside, peonidin-3-rutinoside and malvidin-3-O-β-D-(6”-acetylglucoside). These results suggest that the fruits of Carissa edulis are nutritious and possess potential antidiabetic effect which corroborated the ethnomedical uses of the fruits.
