Аннотация: The study addresses reflection and spectral-polarization characteristics of forest stands and farm crops obtained under field conditions. The study of the reflection properties of farm crops shows that during the summer plant growing season, the major factors influencing the plant canopy reflectance are morpho-physiological parameters, plant architectonics, solar elevation h0, and viewing angle. The crop reflectance minimum was recorded at viewing angles 25-30В° with respect to the nadir. Coniferous and broadleaf forest stands had similar reflectance spectra of polarized light. The polarized component was smaller for all coniferous stands than for broadleaf ones. For broad-leaved farm crops (wheat and corn), the polarized component of the spectral brightness coefficients had a greater influence on the plant reflectance in the red and near-infrared spectral regions, ?>720nm.

Wheat growth on neutral and soil-like substrates: Carbon dioxide exchange and microflora / J. -B. Gros [et al.] // Acta Horticulturae. - 2004. - Vol. 644. - P243-248
Кл.слова (ненормированные):
Carbon dioxide -- Closed ecological system
Аннотация: The soil-like substrate (SLS), which is a potential candidate for employment in closed ecological systems, has been tested. CO2 exchange, composition and numbers of soil microflora have been examined in .wheat-SLS. system. The results produced have been compared to analogous characteristics of .wheat-neutral substrate. system. A hydroponic method was used under wheat growing on the neutral substrate (expanded clay aggregate). Plants for both studies were grown in closed environment from seed to physiological maturity. In the .wheat-SLS. system, the net photosynthetic rate of canopy was positive in the course of 6.55 days after planting. The net photosynthetic rate of canopy in .wheat-neutral substrate. system was positive in the entire course of vegetation. According to calculations in the course of vegetation, photosynthesis has withdrawn 3.28 kg m-2 CO2 from the .wheat-SLS. system and 3.40 kg m-2 CO2 from the .wheat-neutral substrate. system. On the SLS dominant among bacteria were the spore-forming bacteria from Bacillus genus, among fungi . from Trichoderma genus. In the hydroponic cultivation on neutral substrate dominant were bacteria from Pseudomonas genus, most commonly found fungi were species from Fusarium and Botrytis genera.

Аннотация: A mass-flow model of carbon cycle in a bioregenerative life support system (BLSS) including Resource, Plant Growth, Food Processing, Human, Waste Processing, and Waste Storage Modules was developed. A human received food from Plant Growth and Resource Modules. Plants were assumed to be growing on the soil-like substrate (SLS). Another function of SLS was balancing the carbon cycle. The input of BLSS was set to 81 g of carbon per day along with food from the Resource Module. To balance the carbon cycle an equal arnount of carbon was removed from BLSS along with urine, feces, plant wastes, and SLS. A mass flow of carbon cycle was used to simulate the effect of light intensity on the basic parameters of the Plant Growth Module. It was calculated that the stationary dry mass of SLS increases from 10 to 35 kg m(-2) with increase canopy-level daily photosynthetic photon flux (PPF) from 34 to 178 mol m(-2) d(-1). On the contrary dry mass of SLS needed to provide one person with plant food is not dependent on light intensity. (C) 2008 Elsevier Ltd. All rights reserved.

Analysis of polarization characteristics of plant canopies using ground-based remote sensing measurements [Text] / A. F. Sid'ko [et al.] // J. Quant. Spectrosc. Radiat.

Аннотация: The paper presents results and analysis of a study on polarized characteristics of the reflectance factor of different plant canopies under field conditions, using optical remote sensing techniques. Polarization characteristics were recorded from the elevated work platform at heights of 10-18 m in June and July. Measurements were performed using a double-beam spectrophotometer with a polarized light filter attachment, within the spectral range from 400 to 820 nm. The viewing zenith angle was below 20 degree. Birch (Betila pubescens), pine (Pinus sylvestris L.), wheat (Triticum acstivum) [L.] crops, corn (Zea mays L ssp. mays) crops, and various grass canopies were used in this study. The following polarization characteristics were studied: the reflectance factor of the canopy with the polarizer adjusted to transmit the maximum and minimum amounts of light (R-max and R-min), polarized component of the reflectance factor (R-q), and the degree of polarization (P). Wheat, corn, and grass canopies have higher R-max and R-min values than forest plants. The R-q and P values are higher for the birch than for the pine within the wavelength range between 430 and 740 nm. The study shows that polarization characteristics of plant canopies may be used as an effective means of decoding remote sensing data. (C) 2014 Elsevier Ltd. All rights reserved.

A study of seasonal dynamics of herbaceous plant communities in Khakassia using ground-based and satellite data / A. P. Shevyrnogov, N. A. Kononova, A. I.

Аннотация: The present study addresses the seasonal dynamics of productivity and species composition of the meadow and steppe vegetation communities in Khakassia, determined using the ground-based and satellite data of 2017. The MODIS/Terra satellite data were used to analyze the Normalized Difference Vegetation Index (NDVI) and the Land Surface Water Index (LSWI). The NDVI and LSWI were found to be related to the productivity of the meadow and steppe vegetation. The NDVI increased as the portion of the mesophyte grasses in the grass canopy became larger. The LSWI was higher in the steppe communities, which had lower projective coverage, with spots of bare soil, than in the meadow communities, with their abundant vegetation. © Published under licence by IOP Publishing Ltd.

Аннотация: The review is devoted to the study of the internal radiation regime in the canopies cultivated under controlled environmental conditions. The expediency of using canopies as an object of research for evaluating the photobiological efficiency of radiation in light culture conditions is justified. The appropriateness of light measurements in multi-tiered canopies is shown, taking into account the role of leaves of different tiers in the formation of an economically useful crop. The main requirements for light devices for their use in measuring artificial radiation in light culture conditions are considered, and a brief analysis of the existing instrument base for performing these studies is given. A number of examples show the complexity and ambiguity of the internal structure of the light field that is forming within canopies in light culture conditions. Conceptual approaches to the choice of spectral and energy characteristics of artificial irradiation for plant light culture are proposed and justified. The necessity of taking into account the light conditions of leaves of different tiers when choosing the spectral and energy characteristics of light sources for the cultivation of multi-tiered canopies is justified. Techniques, methods, and light sources used for additional intracanopy lighting are analysed. The efficiency of using side illumination of plant canopies and conditions for its implementation are considered. The advantages of the volume distribution of canopies on the most common multi-tiered lighting installations are discussed. Based on the presented mate- rial, we consider ways to improve methodological approaches for evaluating the photobiological effectiveness of artificial radiation in light culture conditions for canopies of cultivated plants, taking into account the features of their architectonics and internal radiation regime.
