Tomato ripening in normal red-fruited cultivar (Fiorin) was delayed by treatment with methyl jasmonate (JA-Me) vapour. A visual scoring system for describing tomato ripening was used. Surface of fruits exposed to JA-Me vapour, increased in yellow and decreased in red as deter mined by HunterLab colour meter. JA-Me significantly altered the firmness of fruits after 21 days storage. Vapour of JA-Me enhanced the level of ß-carotene in outer part (peel with 3 mm pericarp tissue) of fruit, while it had no effect in peeled fruit pericarp. JA-Me treatment decreased the level of lycopene in outer part and pericarp tissue, however, in outer part lycopene content decreased at a higher rate than in pericarp. Amount of tomatine in fruits treated with JA-Me had enhanced four-fold in outer part and by 62% in peeled fruit pericarp as compared with the control.

Dojrzewanie zielonych pomidorów odmiany Fiorin było opóźnione przez pary estru metylowego kwasu jasmonowego (JA-Me). Zastosowano wizualną skalę określającą stopień dojrzałości owoców. Pomiary zabarwienia powierzchni owoców przy użyciu spektrokolorymetru HunterLab wykazały, że pomidory traktowane parami JA-Me były mniej czerwone i bardziej żółte od owoców kontrolnych. Traktowanie parami JA-Me podwyższało zawartość ß-karotenu i obniżało poziom likopenu w skórce i przylegającej do niej tkance perykarpu grubości 3 mm. JA-Me nie powodował zmian zawartości ß-karotenu ale obniżał poziom likopenu (aczkolwiek w mniejszym stopniu niż w skórce) w perykarpie głębszych warstw owoców. Zawartość tomatyny w pomidorach traktowanych parami JA-Me była 4-krotnie wyższa w skórce i przylegającej do niej 3 mm grubości tkance perikarpu i o 62 % wyższa w głębszych warstwach perikarpu w porównaniu z pomidorami kontrolnymi.

This article reviews the literature concerning relation between of some stress factors and biosynthesis of jasmonates in plants. Rapid increase in endogenous levels of jasmonates, mainly jasmonic acid (JA), occurs after wounding of different plant organs, which may be caused by physical injury, pathogen infection, herbivore or insect attack, as well as under osmotic stress conditions and after addition of yeast cell wall elicitors to cell culture suspension. Wounding induces an expression of defense-related genes whose products are mostly involved in defense responses against pathogen and insect attack. Endogenous and exogenous jasmonates could act as signalling substances in the transduction chain between stress and molecular stress response, in most cases of the induction of gene expression and the accumulation of defense specific proteins and secondary metabolites. It was shown that the coronatine phytotoxin, isolated from the cultures of Pseudomonas syringae pv. atropurpurea, indicates similarities to jasmonates in different biological tests.

Biosynthesis of the lycopene, the occurrence and its biological properties in human health are described in this review. Lycopene is a main, naturally present carotenoid in tomatoes and is responsible for the red colour of the fruit. A rich source of the lycopene is also watermelon, guava fruits, and pink grapefruits. High levels of lycopene have been found in different organs of human tissues. Lycopene exhibits highest antioxidant properties among all dietary carotenoids. Several recent epidemiological and experimental studies have indicated the effect of dietary lycopene in reducing risk of different cancer diseases and coronary heart disease. Lycopene is minimally affected by temperature processes. In fact, its bioavailability is increased when it is processed or consumed with adding of some oil to meal.

The content of flavonoids in white and yellow perianths and yellow anthers of a few tulip cultivars were determined at the stage of full flowering. To analyses of flavonols a HPLC method was used. In anthers (yellow) of all analyzed cultivars (Oscar, Pax, Profesor Wóycicki, Biała Dama, White Virgin, Calypso, Diana) high content of quercetin (2.35 - 6.01 mg . g-l EW), kaempferol (1.09 - 9.47 mg . g.1 EW) and apigenin (1.34 - 8.24 mg• g-l EW.) was found. In analyzed white perianth of cvs. Oscar and White Virgin also high content of quercetin (1.3 - 1.80 mg . g-l EW) and kaempferol (1.90 mg . g-l EW.) was documented and only traces of apigenin was found. In the yellow perianth of cv. Profesor Wóycicki the level of quercetin and kaempferol was much lower than in perianth of cvs. Oscar and White Virgin, and apigenin was absent.Thus, yellow anthers and white and yellow perianth of tulip cultivars are a rich source of flavonols.

Analizowano zawartość flawonoidów (metodą HPLC) w białym i żółtym okwiecie i w żółtych pylnikach kilku odmian tulipanów w okresie pełni kwitnienia. W żółtych pylnikach analizowanych odmian (Oscar, Pax, Profesor Wóycicki, Biała Dama, White Virgin, Calypso, Diana) wykazano wysoką zawartość kwercetyny (2,35 - 6,01 mg • g-1 ś.m.), kempferolu (1,09 - 9,47 mg • g-1 ś.m.) i apigeniny (1,34 - 8,24 mg . g-1 ś.m.). W białym okwiecie odmian Oscar i White Virgin stwierdzono również wysoki poziom kwercetyny (1,30- 1,80 mg . g-1 ś.m.) i kempferolu (1,90 mg • g-1 ś.m.), a tylko ilości śladowe apigeniny. W żółtym okwiecie odmiany Profesor Wóycicki zawartość kwercetyny i kempferolu była dużo mniejsza niż w białym okwiecie odmian Oscar i White Virgin, a brak było apigeniny. Tak więc żółte pylniki i biały i żółty okwiat odmian tulipanów są bogatym źródłem flawonoidów.

Tropolone and hinokitiol (β-thujaplicin) that are present in heartwood of several Cupressaceae trees are known for their antibacterial, antifungal and insecticidal properties. In the present studies it was showed that tropolone and hinokitiol greatly inhibited in vitro, on PDA medium, the mycelium growth of Phoma narcissi, a pathogen of Hippeastrum and other species of family Amaryllidaceae. Total inhibition of the mycelium growth of Phoma narcissi took place at a tropolone concentration of 6.0 µg·cm⁻³ and at a hinokitiol concentration of 50.0 µg·cm⁻³. Fungicidal doses of tropolone and hinokitiol for the mycelium growth of Phoma narcissi were also documented. The results presented in this paper are discussed with data available in literature on the antifungal action of tropolone and hinokitiol on other species of pathogenic fungi.

Tropolone i hinokitiol (β-tujaplicyna), występujące w wielu gatunkach drzew należących do rodziny Cupressaceae, mają właściwości antybakteryjne, antygrzybowe i insektycidalne. W obecnych badaniach wykazano, że tropolone i hinokitiol silnie hamowały in vitro na pożywce PDA wzrost grzybni Phoma narcissi, patogena Hippeastrum i innych gatunków z rodziny Amaryllidaceae. Całkowite zahamowanie wzrostu grzybni Phoma narcissi następowało przy stężeniu tropolone 6,0 µg·cm⁻³ i przy stężeniu hinokitiolu 50,0 µg·cm⁻³. Fungicidalne stężenia tropolone i hinokitiolu zostały również określone. Wyniki badań własnych zostały przedyskutowane z dostępnymi danymi w literaturze o antygrzybowym działaniu tropolone i hinokitiolu na inne gatunki grzybów patogenicznych.
