QUANTITATIVE DESCRIPTION OF SLOW INDUCTION OF CHLOROPHYLL FLUORESCENCE DURING ONTOGENY OF HIGHER-PLANT LEAVES [Text] / T. V. NESTERENKO, F. Y. SIDKO // RUSSIAN PLANT PHYSIOLOGY. - 1993. - Vol. 40, Is. 1. - P. 5-10. - Cited References: 23 . - ISSN 1070-3292

CUCUMIS-SATIVUS -- LEAVES -- ONTOGENY -- CHLOROPHYLL FLUORESCENCE
Аннотация: Additional integral and kinetic parameters of induction curves have been introduced on the basis of analysis of currently employed parameters of slow induction of fluorescence (SIF) for a more complete quantitative description of SIF changes during ontogenesis of higher plant leaves. High sensitivity of the additional parameters to the age state of leaf tissue as compared with previously employed parameters is demonstrated on the example of cucumber leaves (Cucumis sativus L.). Analysis of the relationship between the photosynthetic rate and SIF parameters of separate cucumber leaf disks revealed the presence of a high positive correlation between the photosynthetic rate and the greatest possible average decline in fluorescence intensity during the inductive period for mature regions of the leaf and regions starting to senesce (the correlation coeffcient attained values of 0.95), which indicates the possibility of using the given SIF parameter in further elaboration of methods for estimation of chloroplast photosynthetic activity at the level of the higher plant leaf.

Photosynthetic apparatus of cucumber and pea plants grown under red light with discrete or continuous spectra / E. N. Zavorueva [et al.] // Russian Journal of Plant Physiology. - 1996. - Vol. 43, Is. 2. - P191-199 . - ISSN 1021-4437
Кл.слова (ненормированные):
And thermoinduced changes in fluorescence yield -- Cucumis sativum -- Photo -- Photophosphorylation -- Pigments -- Pisum sativum
Аннотация: The effect of light sources with discrete or continuous spectra of red light (50 W/m2, 600-700 nm) on the structural and functional characteristics of chloroplasts were studied in leaves of cucumber (Cucumis sativum L.) plants, which die under strong red light, and pea (Pisum sativum L.) plants, which tolerate red light under the same conditions. Leaf condition was assessed by measuring thermo-and photoinduced changes in the chlorophyll fluorescence yield and the photochemical and photophosphorylating activities of the chloroplasts. Different responses of the pigment apparatus of pea and cucumber plants to red light with continuous or line spectra were revealed. Pea plants responded to discrete-spectrum light by changing P700 content, the ratio of antenna chlorophyll to P700, and the position of the low-temperature peak of the temperature-induced chlorophyll fluorescence yield. In cucumber plants, disturbances in the energy transfer from the short-wavelength pigments to chlorophyll a were observed. In both plants, the effects of line spectrum light on the pigment apparatus were reversible; the ratio of cyclic to noncyclic photophosphorylation, photosynthetic control, and the extent of the coupling of photosynthetic electron transport to photophosphorylation did not change compared to the control light. The need for examining the line spectra of light sources for growing plants under moderate intensities of artificial light (about 50 W/m2 of photosynthetically active radiation) is discussed.

Fine chloroplast structure in cucumber and pea leaves developed under red light / E. N. Zavorueva [et al.] // Russian Journal of Plant Physiology. - 2000. - Vol. 47, Is. 6. - P740-747 . - ISSN 1021-4437
Кл.слова (ненормированные):
Cucumis sativus -- Pigments -- Pisum sativum -- Red light -- Ultrastructure
Аннотация: Photosynthetic activity, the content of various photosynthetic pigments, and the chloroplast ultrastructure were examined in the leaves of cucumber (Cucumis sativus L.) and pea (Pisum sativum L.) plants of different ages grown under red light (600-700 nm, 100 W/m2). In pea leaves tolerant to red-light irradiation, chloroplast ultrastructure did not essentially change. In the first true leaves of cucumber plants susceptible to red-light irradiation, we observed a considerable increase in the number and size of plastoglobules, the appearance of chloroplasts lacking grana or containing only infrequent grana, and stromal thylakoids. In the upper leaves of 22-day-old cucumber plants, the chloroplast structure was essentially similar to that of the control chloroplasts in white light, and we therefore suppose that these plants have acclimated to red light.

Evaluation of the effect of light intensity on the measurement of the photosynthetic rate in plankton microalgae by the chlorophyll fluorescence method [Text] / N. A. Gaevskii [et al.] // Russ. J.

Аннотация: The use of relative variable fluorescence (RVF) of chlorophyll, as measured in the presence of Diuron, an inhibitor of electron transfer, for the estimation of the photosynthetic activity of plankton microalgae was analyzed under a wide range of light intensities in the PAR region. Oxygen evolution rates (estimated by the method of light and dark bottles and the amperometric method), RVF, and chlorophyll a concentration were measured in parallel in natural algal cenoses and microecosystems. When the previously used regression equation, in the form A = b(DeltaF/F-d)CchlI, where A is O-2 evolution rate (g/(m(3) h), DeltaF/F-d is RVF (relative units), C-chl is chlorophyll a concentration (mg/m(3)), and I is light intensity (W/m(2)), was verified in the PAR region, we observed a nonlinear dependence of the correction coefficient b on I, which can be described by the formula b = 6.227 x 10(3)rootI. This result agrees with the hypothesis that chlorophyll a fluorescence quenching comprises photochemical (qQ) and energy (qE) components. On the basis of the energy model, we determined the upper limit b(max) = 0.003 for light intensity range I < 4.4 W/m(2) and the lower limit b(min) = 0.0003 for I = 400 W/m(2).

Gut content analysis of Gammarus lacustris from a Siberian lake using biochemical and biophysical methods / M. I. Gladyshev [et al.] // Hydrobiologia. - 2000. - Vol. 431, Is. 2-3. - P155-163 . - ISSN 0018-8158
Кл.слова (ненормированные):
Chlorophyll fluorescence -- Fatty acid composition -- Viable gut passage -- crustacean -- diet -- saline lake -- seston -- stomach content -- Russian Federation
Аннотация: We studied the gut contents of Gammarus lacustris from the littoral of Shira lake, a Siberian salt lake, by microscopic analysis in conjunction with measuring of fluorescence of chlorophyll and composition of fatty acids. Gammarus ingested primarily fresh seston, probably settled on the bottom. Additionally, the amphipods obtained essential polyunsaturated fatty acids of ?3 family by selectively consuming bottom sediment particles. A considerable part of the ingested seston comprised cells of Botryococcus sp., which passed the intestinal tract in living form and their photosynthetic activity increased. This viable gut passage was likely one of the causes of bloom of Botryococcus in the littoral. Unlike a number of literature data, there was no selective digestion of any fatty acid species, including polyunsaturated acids, in the intestinal tract.

The levels of organization of the photosynthetic apparatus and the control of production processes in phytocenoses under artificial-light culture / A. A. Tikhomirov, G. M.

Кл.слова (ненормированные):
Artificial-light culture -- Photosynthetic apparatus -- Phytocenosis -- Productivity -- Embryophyta
Аннотация: The processes limiting the production in higher plant phytocenoses under an artificial-light culture are analyzed in relation to the multilevel organization of the photosynthetic apparatus (PA). The authors consider the feasibility of overcoming these limitations by optimizing the physical parameters of irradiation (the structure of the light spectrum, the rate, and the ratio of radiation fluxes in photosynthetically active radiation (PAR) and infrared (IR) regions) at the molecular, leaf, plant, and cenotic levels of PA organization. To illustrate this approach, the authors used a complex experiment in an artificial ecosystem to evaluate the efficiency of the light control of production processes in multispecies phytocenoses by alleviating or removing the factors that limit plant production at the various levels of PA organization. An artificial-light culture is seen as an instrument for solving several problems of theoretical and applied plant physiology and related disciplines in the future.

Аннотация: Stability of LSS based on biological regeneration of water, air and food subject to damaging factors is largely dependent on the behavior of the photosynthesizing component represented, mainly, by higher plants. The purpose of this study is to evaluate the tolerance of uneven-aged wheat and radish cenoses to temperature effects different in time and value. Estimation of thermal tolerance of plants demonstrated that exposure for 20 h to the temperature increasing to 45В°C brought about irreversible damage both in photosynthetic processes (up to 80% of initial value) and the processes of growth and development. Kinetics of visible photosynthesis during exposure to elevated temperatures can be used to evaluate critical exposure time within the range of which the damage of metabolic processes is reversible. With varying light intensity and air temperature it is possible to find a time period admissible for the plants to stay under adverse conditions without considerable damage of metabolic processes.

Аннотация: The heat tolerance of wheat (Triticum aestivum L.) and radish (Raphanus sativus L. var. minor) cenoses exposed to elevated and damaging air temperatures (35 degreesC for 20 h, 45 degreesC for 7 h) under photoculture conditions at various levels of photosynthetically active radiation (PAR) was assessed by measuring characteristics of the slow induction curve of chlorophyll fluorescence at 682 and 734 nm and the CO2 exchange rate. Irrespective of the illumination level, the exposure of the cenoses to 35 degreesC did not induce irreversible changes in the plant photosynthetic apparatus. The lowest extent of damage to wheat and radish cenoses exposed to 45 degreesC was observed at 150 W/m(2) of PAR, whereas the highest damage of the plants was observed at an illumination level that was close to the compensation point of the cenose photosynthesis (50-70 W/m(2) of PAR at air temperature of 24 degreesC). Viability index proved to be the most sensitive. characteristic, compared to other characteristics, which were determined by measuring the slow phase of fluorescence induction at 682 and 734 nm. In the cenoses studied, the pattern of changes in the viability index in response to a stress factor was close to the changes in the photosynthetic rate.

Аннотация: An optical remote assay for biological production of crops in the field during the vegetation period is proposed. Our calculations demonstrate a good correlation between the S(t) value and crop yield (in the range from 0.85 to 0.90); the higher is S(t) for the vegetation period, the higher is the crop yield. S(t) value can be used to calculate the increase in dry and wet biomass for various crops during the whole vegetation period with an error of less than 10-12%. The absolute error of crop yield for 110 cultivars of wheat, oats, and barley during the experimental period was +/-3-3.5 quintal/ha with the mean crop yield of 14-38 quintal/ha.
