Optical properties and changes in the content of photo synthetic pigments (chlorophyll and total carotenoids) were investigated in the bark and leaves of the apple-tree during a year. Optical properties of stems change with their age. Light reflectance of current year stems equalled 14.2 %, while the one for 3-year-old stems decreased to 10.2 %, absorption for the current year stems equalled 55.5 % and increased up to 66.4 % for 3-year-old ones. Light transmittance for the cork of current year stems equalled 30.2 %, and decreased with the age of stems reaching 23.4 % for the 3-year-old ones. The cork transmitted less than 5 % of light of 400 nm, but the transmittance increased with the increase in the wavelength up to 55 % at 700 nm. The reflectance of light by the leaf equalled 6.9 %, absorption 89.7 %, and transmittance 3.4 %. In August the highest amount of chlorophyll pigments (6.2 mg-dm-2) and carotenoids (1.63 mg-dm-2) was detected in the leaves of the apple-tree, however, the ratio of chl alb reached the highest value 4.12 in June. For the bark of apple-tree stems the content of chlorophyll pigments increased since spring and reached the maximum content of about 2.8 mg(chl)-dm-2 for 1-3-year-old stems in the summer months, while for the current year stems in October. The ratio chl alb was at the same level, about 2.2 during the whole year. The content of carotenoids was lower in stems than in leaves and was at the similar level during the year, however, it increased with the age of stems. Minor changes in the optical properties and the content of photosynthetic pigments occurring with the age of stems may be due to the low increment in cork thickness in the studied age groups of plants.

The distribution of chlorophyll was examined in cross-sections of 2- and 6-year-old stems as well as in the bark of the stump trunk of beech trees, utilising chlorophyll autofluorescence. The investigations were conducted using a confocal microscope. The tests carried out on 2 - 6-year old stems showed a large presence of chlorophyll in the bark, in primary and secondary rays as well as in the pith, but smaller amounts in wood parenchyma cells. There was no chlorophyll in the cork, sclerenchyma: in wood in vessels, tracheids and fibers. A reduction in the chlorophyll content in 6-year-old stems was not observed. In the bark of the trunk, chlorophyll was found in large amounts directly under the cork and in vestigial amounts in the primary phloem.

The investigations were carried out on 1-3- and 10-year-old stems and on the trunks of beech. The optical properties measured were: reflectance, absorption and transmittance of irradiation. The reflectance was measured in the bark and the cork, while absorption and transmittance were measured on isolated cork. Reflectance was measured only on the bark of trunks and the range of the investigations was 400-1100 nm. The reflectance of irradiation in the stems increased with increasing wavelength and decreased with the age of stems. In the range 400-700 nm it ranged from 18% in 1-year-old stems to 10% in 10-year-old stems, and reflectance in the trunks was equal to 15%. In the range 700-1100 nm, it ranged from 51% in 1-year-old stems to 36% in 10-year-old stems and in the trunks. Absorption of the cork decreased with increasing wavelength from about 92% in the range 400 nm to about 15% in the range 700 nm, and to 15% in the range 1100 nm. Any distinct influence of stems age on cork absorption was not observed. Transmittance of irradiation increased with increasing wavelength and the age of the stems. In the range 400 nm it was >1% in all age groups of the stems. In the range 700 nm in 1- and 2-year-old stems, it was equal to approximately 45%, and in the 10-year-old ones it amounted to 60%. In the range 700-750 nm, transmittance decreased to about 38% in the bark of 1-3-year-old stems, to 50% in 10-year-old ones and it remained at this level up to 1100 nm.

The response of aerial parts of lemon balm and basil to 7-day soil drought and root submergence (waterlogging) was studied. Drought-subjected basil plants inhibited the growth of their shoots, and water content in leaves dropped to ca. 60% of leaf fresh weight, whereas growth of lemon balm was not affected and water content was ca. 70%. Gas exchange of lemon balm was stopped, which was considered an adaptive feature, and fluorescence parameters of chlorophyll a (Fv/Fm and Fv/F0) were not influenced. On the contrary, basil had its transpiration rate, stomatal conductance, and fluorescence parameters at the level of 40% of control, and CO2 exchange switched from net photosynthesis to respiration. In the case of waterlogging, neither gas exchange, nor other parameters of lemon balm were altered, revealing insensitivity of plants to hypoxic stress, whereas gas exchange of basil was ca. 1/3 of the control. Both treatments increased anthocyanin content in lemon balm leaves, which may partially contribute to the resistance of this species to photooxidative conditions triggered by water stress.

Do doświadczeń wybrano rdestowca ostrokończystego (Reynoutria japonica Houtt.) którego łodygi posiadają obszerne kanały rdzeniowe. Rośliny uprawiane były w warunkach naturalnych. W warunkach naturalnych łodygi rdestowca są ocienione przez liście i rzadko są narażone na bezpośrednie oświetlenie promieniowaniem słonecznym. Badania wykazały, że w kanałach rdzeniowych rdestowa w ciągu nocy stężenie CO2 może przekraczać 10%, a ciągu dnia następuje zmniejszanie tego stężenia nawet poniżej 1%. Zmianom stężenia zawartości CO2 towarzyszą podobne wielkością lecz przeciwnie skierowane zmiany zawartości O2: zmniejszanie się jego zawartości w nocy i zwiększanie w ciągu dnia. Wprowadzenie nadmiernego oświetlenia łodyg doprowadziło do zmian zawartości CO2 i O2. Ze wzrostem intensywności oświetlenia szybciej malała zawartość CO2 i szybciej wzrastała zawartość tlenu w kanałach rdzeniowych. Zmiana warunków świetlnych ułatwiała reasymilację CO2 zgromadzonego w godzinach nocnych przez łodygę. W ciemności uwalnianie tego gazu w kanałach rdzeniowych wynosi około 0,6 µmol CO2·m-2·s-1, a świetlny punkt kompensacyjny reasymilacji uzyskiwano w intensywności napromieniowania około 80 µmol·m-2·s-1. Natomiast świetlne wysycenie reasymilacji notowano przy napromieniowaniu około 850 µmol·m-2·s-1 z intensywnością reasymilacji wynoszącą około 0,9 µmol CO2·m-2·s-1. Badania wykazały że nienaturalnie wysokie dawki promieniowania nie są czynnikiem stresowym dla łodyg rdestowca a wręcz przyczyniają się do szybszego zużywania CO2 i nagromadzania O2.
