Leaf age, seasonal and annual variations in Salvia officinalis L. var. purpurascens biochemical characteristics

Filipa Martins, Ivo Oliveira, Ana Barros, Carla Amaral, Sílvia Afonso, Helena Ferreira & Berta Gonçalves
Medicinal and aromatic plants (MAP’s) have gain new attention in the past years due to their content in bioactive compounds and recognized health-promoting effects. One of the most important species of MAP’s is Salvia officinalis L., rich in several phytochemicals (essential oil, phenolic compounds) and vitamins. Besides, it has various uses and pharmacological effects (including antibacterial, antiviral, antioxidative, anti-inflammatory, antidiabetic and antitumour activities). Salvia officinalis L. has many cultivars, including Salvia officinalis L. var. purpurascens,...

Influence of four different dwarfing rootstocks on phenolic acids and anthocyanin composition of sweet cherry (Prunus avium L) cvs 'Kordia' and 'Regina'

Bernardica Milinović, Verica Dragović-Uzelac, Dunja Halapija Kazija, Tvrtko Jelačić, Predrag Vujević, Danijel Čiček, Ante Biško & Zlatko Čmelik
Influence of four different dwarfing rootstocks: ‘Gisela 5’, ‘Gisela 6’, ‘PHL-C’ and ‘PiKU1’ on the amount of polyphenols (total phenols, total and individual anthocyanins and individual hydroxycinnamic acids) of sweet cherry cultivars ‘Kordia’ and ‘Regina’ was researched as well as correlations between polyphenols and colorimetrically measured fruit skin colour. Total phenols (TP) and total anthocyanins (TA) were determined by spectroscopic methods, while individual anthocyanins and hydroxycinnamic were quantified and identified by high performance liquid chromatography...

Reduced grapevine canopy size post-flowering via mechanical trimming alters ripening and yield of 'Pinot noir'

A. K. Parker, V. Raw, D. Martin, S. Haycock, E. Sherman & M. C. T. Trought
The degree and time of canopy trimming can alter phenology, rates of increase or decrease in berry components during grape ripening, and may influence yield and its components. The objective of this study was to investigate the extent to which reducing canopy size, by mechanical trimming post-flowering, changed Vitis vinifera L. 'Pinot noir' fruit yield and composition. Vines were mechanically trimmed to three different canopy heights at fruitset: 1000 mm (100 % canopy height), 600...

Chlorophyll and carotenoid quantifications in white grape (Vitis vinifera L.) skins by reflectance spectroscopy

L. Rocchi, L. Rustioni & O. Failla
In white grapes, chlorophylls and carotenoids play important roles in berry color and environmental interactions (e.g. radiative stresses). In this paper, easy, fast and low cost non-invasive reflectance methods have been tested and developed. Previously published indexes showed good performances for chlorophyll quantifications. However, in this work, new formulas able to discriminate chlorophylls a and b were also proposed. The wavelengths of major interest for the absorption detection were identified. Formulas based on the Gaussians...

Variation in bioactive contents and anatomical characteristics of different fennel (Foeniculum vulgare Mill.) populations as affected by self-pollination

Maryam Salami, Mehdi Rahimmalek, Mohammad Hossein Ehtemam & Mohammad Reza Sabzalian
The production of self pollinated plant genotypes could be critical for improving medicinal plants. Pollination in Apiaceae family can also affect secondary metabolites. In this study, 23 fennel populations were used to assess the effect of self pollination on essential oil yield, antioxidant activity (based on three model system), total phenolic (TPC) and flavonoid content (TFC). First, some plant inflorescences were divided in two parts. Then the half was bagged and the second half was...

Impact of direct-electric-current on growth and bioactive compounds of African nightshade (Solanum scabrum Mill.) plants

Elisha Otieno Gogo, Susanne Huyskens-Keil, Anja Krimlowski, Christian Ulrichs, Uwe Schmidt, Arnold Opiyo & Dennis Dannehl
Production of indigenous African leafy vegetables such as African nightshade (Solanum scabrum Mill.), whose high nutritional and medicinal value is well documented is still limited due to insufficient preharvest techniques. Electric current is known to improve quality in food crops. Therefore, in the present study, the effects of direct-electric-current (DC) on growth and characteristic bioactive and health promoting compounds were evaluated in different morphological sections, i.e., leaves and stems of African nightshade cv. Olevolosi. Six...

Can plant bio-regulators minimize crop productivity losses caused by drought, heat and salinity stress? An integrated review

Ratna Kumar Pasala, M. I. R. Khan, Minhas P.S., Farooq M.A., Sultana R, T. S. Per, Deokate P.P., Khan N.A. & J. Rane
Plant bio-regulators (PBRs), are biochemical compounds which stimulate plant growth and productivity when applied, even in small quantities at appropriate plant growth stages. These are being extensively used in agriculture to enhance the productivity particularly in horticultural crops but are not as prevalent in field crops. Their central role in plant growth and development is through nutrient allocation and source-sink transitions while some of the PBRs stimulate hormones related to abiotic stress tolerance. Since climate...
