| Experiment Detail |
Whole leaves and inflorescences of two wild strawberry cultivars ('Rugia' and 'Baron von Solemacher') harvested in 2008 during the agrotechnical experiment performed by Department of Vegetable and Medicinal Plants, University of Life Sciences in Lublin, were used as a material for determinations. Samples were collected before noon at sunny and dry days at the beginning of wild strawberry's flowering stage. Material was dried up to 35 ℃ in shadow and air just after the harvest.

| Factor Function |
Depending on a cultivar, air-dry inflorescences from wild strawberry contain from 0.21% ('Baron von Solemacher' cv.) to 0.30% ('Rugia' cv.), whereas leaves contains from 0.46% ('Baron von Solemacher' cv.) to 0.62% ('Rugia' cv.) of essential oils. GC/MS analysis of essential oils achieved from studied materials revealed presence of 70 (including 59 identified) compounds in leaves of 'Rugia' cv. and 58 (including 50 identified) compounds in leaves of 'Baron von Solemacher' cv. Essential oils from inflorescences of 'Rugia' cv. contained 52 (including 47 identified), while 'Baron von Solemacher' cv. contained 54 (including 46 identified) compounds. The chromatographic analyses by GC-MS revealed that myrthenol, nonal, linalool and phthalide dibuthyl dominated in essential oils obtained from leaves, while myrthenol, citronelol, linalool and geraniol - from those of inflorescences. There were qualitative differences between oil components at both studied materials and differentiation between both cultivars, as well.

More than 70 constituents were identified (64 positively and 10 tentatively) in the oils. alpha-Pinene (18.5-33.0%) and delta-3-carene (9.1-24.6%) were dominating constituents with the only one exception when the germacrene-4-ol content in one of the samples was 13.2%. The important bornyl acetate content varied from 0.5% to 3.0%. The main sesquiterpenes were beta-caryophyllene, germacrene D, bicyclogermacrene, delta-cadinene, gamma-cadinene, germacrene D-4-ol, cubenol (2.0-5.1%) and alpha-cadinol (1.9-7.7%).

| Experiment Detail |
Aerial parts of Solidago virgaurea plants were randomly collected from the wild at two different altitudes, as described below, during the 2000 vegetation period. All the collections of the plant samples were carried out during massive bud formation and the beginning of flowering stage. Sample # 1, LTS00-46; 10 kg of the sample was collected on July 31, 2000 at LAT: 51° 07′ LON: 81° 10′ HEI 290 m from Altai land, Lokteev district, near the village of NovoMikhaylovskoe, on the left bank of the Aley River, outskirts of pine forest, fire area, sandy soils. Sample # 2, LTS00-57; 5.6 kg of the sample was collected on August 3, 2000 at LAT 51° 14′ LON 82° 28′ HEI 650 m from Altai land, Kur'in district, around the Kolyvanm quarries, with diverse turf grasses, along the river bank of Aley.

The main components from 290 m were alpha-pinene (36.5%), myrcene (14.8%), beta-caryophyllene (10.5%), germacrene D (8.2%), beta-pinene (7.1%) and limonene+beta-phellandrene (6.4%). The oil from the sample collected at 650 m had benzyl benzoate (57.0%), beta-caryophyllene (6.3%), germacrene D (6.0%), alpha-pinene (4.4%) and alpha-humulene (4.0%) as major components, suggesting polymorphism or the existence of different chemoytpes.

||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Factor Function |
The Corsican and Sardinian oils of T. chamaedrys investigated in this study were qualitatively similar but they differed by the amount of their major components. The major components were beta-caryophyllene (29.0% and 27.4%, respectively) and germacrene D (19.4% and 13.5%, respectively), followed by alpha-humulene (6.8%) and delta-cadinene (5.4%) in the Corsican oil and by caryophyllene oxide (12.3%) and alpha-humulene (6.5%) in the Sardinian oil. These quantitative differences are also noticeable on the amounts of the different class compounds. Especially, the monoterpene hydrocarbons amounted for 10.3% and 4.1% in Sardinian and Corsican oils respectively and the oxygenated sesquiterpenes amounted for 18.9% and only 7.4% in both oils, respectively. Both oils were qualitatively rather similar in comparison with those reported in the literature from various geographic regions. However, among the 87 components identified in this study, 47 minor components (< 0.6%) reported were identified for the first time in T. chamaedrys oil. This study confirms the quantitative variability of the major components according to the plant origin.

| Experiment Detail |
The aerial parts of T. flavum were collected in different periods from December to July 2006, from plants growing along the Ionic coast of Sicily (Italy). LF 1-LF 2-LF 3: represent the composition of leaf oils of plant samples collected in December (vegetative stage), February (pre-flowering stage) and April (budding stage) respectively; FL: flower oil; FR: fruit oil.

||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Factor Function |
Some components, in all investigated plant parts, remained more or less constant during all the different phases of the plant cycle life. Worthy of note, considering the leaf oils, was that beta-pinene, limonene and germacrene D increased in the pre-flowering stage, while a series of esters and alpha-copaene, beta-caryophyllene, viridiflorol, Tmuurolol and phytol increased in the budding stage (LF3); the vegetative stage oil is generally characterized by a rich chemical composition and some constituents such as isoamyl hexanoate, alpha-humulene, bicyclogermacrene, beta-bisabolene and alpha-bisabolol reached their highest levels in this oil. In the flower oil, linalool and 1-octen-3-yl acetate were the main components compared to the amounts found in the other oils. Fruit oil composition was relatively oil poor, with beta-bisabolene, caryophyllene oxide, cadin-4-en-1-ol and phytone as the major constituents.

| Species Name: Vitis vinifera cv. Pinot noir | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Factor Name: Drought Stress Treatment | [6] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Experiment Detail |
3-year old single shoot V. vinifera plants (cultivar Pinot noir 18 Gm grafted on Kober 5BB, 51 plants) potted in 3L pots in a sandy loam soil were used. All plants were well watered (200 mL per day) at the beginning of the experiment (04.06.2010; DAY 0; 5 plants) and water was supplied to all control plants once every day (250 mL per day), whereas water supply of stressed plants was stopped. Physiological measurements and sampling of leaves took place on 07.06.2010 (DAY 3; 5 control, 5 stressed plants), 10.06.2010 (DAY 6; 5 control, 5 stressed plants) and 12.06.2010 (DAY 8; 5 control, 10 stressed plants). Due to very hot weather conditions in June 2010 the experiment was stopped after 8 days and 12 available control plants were used to restart the drought treatment with 6 control and 6 stressed plants on 11.06.2010 and all plants were measured on 15.06.2010 (DAY 5). The mean leaf temperatures at midday were: 25 ℃ (04.06.2010; DAY 0), 31.9 ℃ (07.06.2010; DAY 3), 30.8 ℃ (15.06.2010; DAY 5), 35.8 ℃ (10.06.2010; DAY 6) and 35.7 ℃ (12.06.2010; DAY 8). The mean PAR radiation per day (measured from 6:00 am till 7:00 pm) was 144.1 µmol m-2 s-1. Each plant was used only once for physiological measurements and sampling of leaves.On every day of the experiment (day 0, 3, 5, 6, 8) the pot weight and the volumetric soil moisture content (ThetaProbe ML2x and handheld data logger Moisture Meter HH2, Delta-T Devices, Cambridge, United Kingdom) was recorded. The water potential (PWSC Model 3000, Soilmoisture Equipment Corporation, Santa Barbara, USA) was determined for the 6th leaf (representing the insertion level of the shoot from the basis) of every plant and measurement day. Chlorophyll fluorescence and gas exchange parameters of light adapted leaves were determined with the 4th and 5th leaf, whereas dark adaptation was performed only with the 5th leaf. Immediately after these non-invasive measurements, the 5th leaf was harvested, frozen in liquid nitrogen and further used for the measurement of polyphenols, selected primary metabolites and volatiles (VOCs).

| Factor Function |
The content of different groups of primary and secondary metabolites is significantly influenced by severe drought stress in grapevine leaves. The content of the majority of the metabolites (around 60% of primary metabolites, around 85% of polyphenols and about 40% of the detected and identified VOCs) increased upon drought stress treatment. Among these especially the primary metabolites citric acid and glyceric acid were strongly influenced by the short as well as the prolonged drought stress treatment, whereas all polyphenols were only induced upon the prolonged drought stress treatment.
