Аннотация: The purpose of the present study was to investigate the efficacy of the experimental formulations of the metribuzin (MET) and tribenuron-methyl (TBM) herbicides embedded in the matrix of degradable poly-3-hydroxybutyrate blended with wood flour in field-grown tomato and beet crops infested by weeds. There is a necessity to develop environmentally friendly and effective means to protect plants because of the shortcomings of the free herbicide forms such as the environmentally unsafe spray application of solutions and suspensions of the widespread metribuzin and tribenuron-methyl herbicides, removal from soil during watering events and rains, and transport to natural aquatic environments, where the herbicides accumulate in the trophic chains of biota. Free TBM is also rapidly inactivated in soil and metabolized to nontoxic products in plants. The efficacy of experimental formulations of metribuzin and tribenuron-methyl embedded in the matrix of degradable poly-3-hydroxybutyrate blended with wood flour was tested in field-grown tomato and beet crops infested with weeds. Application of metribuzin resulted in the highest productivity of tomatoes (2.3 kg/m(2)) and table beet (3.4 kg/m(2)), improved biometric parameters of tomato fruits and beet roots, and caused reduction in nitrate nitrogen concentrations in them. The mode of herbicide delivery did not affect sugar contents, but application of both metribuzin and tribenuron-methyl induced a 1.7-fold and 1.4-fold, respectively, increase in vitamin C concentrations in tomato fruits and beet roots relative to the vegetables grown on the subplots treated with free herbicides and the intact plants. Embedded herbicides can be used as preemergence herbicides in the field.

Заглавие : Interconnection between the spectral brightness of tomato plants grown under artificial lighting and their physiological parameters and biological productivity
Место публикации : Earth Observ. Remote Sens.: HARWOOD ACAD PUBL GMBH, 1999. - Vol. 15, Is. 5. - С. 777-790. - 14. - ISSN 1024-5251

Аннотация: Optical remote methods were used for experimental determination of values of the spectral brightness coefficients (SBC) of tomato plants, grown under artificial lighting, throughout the growth period. Based on simple criteria of the ratios of the SEC it was demonstrated that it is possible to determine the physiological stress state and biological productivity of plants. The possibility of early diagnosis of the productivity of tomato plants was demonstrated.

Заглавие : Photosynthesis and respiration in plants grown under red and white light
Место публикации : Russian Journal of Plant Physiology. - 1997. - Vol. 44, Is. 3. - С. 317-321. - ISSN 10214437 (ISSN)
Ключевые слова (''Своб.индексиров.''): cucumis sativus--dark respiration--helianthus annuus--line-structured spectrum--lycopersicon esculentum--photosynthesis--plant resistance--red light--respiration in light
Аннотация: Tomato (Lycopersicon esculentum Mill), sunflower (Helianthus annuus L.), and cucumber (Cucumis sativus L.) plants were grown under red or white light at a radiance of 115 W/m2 under controlled conditions. The red spectra were characterized by either two well-distinguished spectral lines (RL1) or only one (RL2). Apparent photosynthesis (Pa), gross photosynthesis (Pg), dark (Rd), and light (R1) respiration, the content of pigments, and the biochemical composition of plants were estimated. Enhancing the destructive red light influence led to a rise in the Pa/R1 and Pa/Pg ratios and to a decrease in chlorophyll a, nitrate, and reduced nitrogen. RL1 was more inhibitory for plants than RL2. It is concluded that declined energy efficiency of respiration contributes to the destructive effect of RL in sunflower and cucumber plants. The rearrangement of metabolic processes, at which energy efficiency of respiration is maintained, is responsible for adaptation of tomato plants to red light. The obtained results allow one to outline the ways to study the species-specific mechanisms of plant responses to prolonged RL action.

Заглавие : SPECTRAL COMPOSITION OF LIGHT AND SOME CHARACTERISTICS OF LEAF MESOSTRUCTURE IN DIFFERENT PLANTS

Ключевые слова (''Своб.индексиров.''): radiation spectrum--leaf mesostructure--species specificity
Аннотация: Cross sections and macerates were used to study leaf mesostructure in cucumber, sunflower, and tomato plants formed under controlled environmental conditions at an irradiance of 100 W.m-2 in the red and blue regions of the spectrum. White light served as the control. Three types of response to red light were isolated: the first type is a response not associated with harmful action of the light factor (tomato); the second a response associated with reversible changes of mesostructure (sunflower); and the third a response associated with irreversible changes of leaf mesostructure (cucumber). It is concluded that destructive changes during prolonged action of red radiation on the leaf are mainly associated with degradation of palisade parenchyma, whereas spongy parenchyma suffers less and takes upon itself the main functional role in certain species (sunflower). Species specificity was not clarified in the response of leaf mesostructure to radiation in the blue region of the spectrum.

Заглавие : Thermoinduction of chlorophyll fluorescence and the age-related condition of higher plant leaves
Колич.характеристики :8 с

Ключевые слова (''Своб.индексиров.''): thermoinduction of chlorophyll fluorescence--leaf--development
Аннотация: The age-related changes in the temperature dependence curves (TDC) of chlorophyll fluorescence were studied in leaf segments of wheat (Triticum aestivum L.), tomato (Lycopersicum esculentum Mill.), and cucumber (Cucumis sativum L.) plants grown under controlled photoculture conditions. Three major TDC patterns of chlorophyll fluorescence were identified within the temperature range of 25-70 degreesC, with each of the patterns corresponding to a certain phase of leaf development. The transition from one type of thermogram to another was a gradual and ordered process. The magnitude of the low-temperature TDC peak increased until leaves completely expanded and declined with leaf senescence. In the course of leaf senescence, the thermograms exhibited an additional shoulder, which further changed into a peak at 55-65 degreesC with increasing magnitude. Our data provide the basis for assessing leaf age from the type of chlorophyll fluorescence thermogram and the changes in the particular indices characteristic of TDC of chlorophyll fluorescence.
