The potential of the method fluorescence spectroscopy for detection damage and diseases fruits vegetables was studied. For this purpose, spectra healthy rotten apples potatoes have been investigated. Excitation samples carried out using a continuous semiconductor laser with wavelength 405 nm pulsed solid-state 527 nm. Peaks in region 600–700 were shifted towards shorter wavelengths most both modes spectroscopy. differences apple surface revealed to be spectral range 550–650 excitation. When...
In this study, we investigated the effects of additional ultraviolet radiation (UV) on main growth fluorescent lamp light pigment content and essential oil accumulation in sweet basil (Ocimum basilicum L.). Three different UV sources from light-emitting diodes discharge lamps, which emit UV-A (315–400 nm), UV-B (280–315 nm) UV-C (100–280 ranges, were tested for plant growing. The plants, growing under mercury 60th day higher than control plants by 90% 53%, respectively. fresh leaf mass...
Lighting conditions are an important controller of plant growth and development, they affect secondary metabolite synthesis. In this research, we explored the effect additional UV irradiation various ranges in addition to main one at PPFD 160 µmol m−2 s−1 on accumulation some metabolites stevia (Stevia rebaudiana Bertoni). The fresh weight leaves was slightly higher under UV-A UV-B compared with control variant, leaf surface area significantly larger, respectively, by 23.3 20.7% than while...
The effects of different spectral compositions light-emitting diode (LED) sources and fertilizer containing biologically active silicon (Si) in the nutrient solution on morphological physiological plant response were studied. Qualitative indicators productivity plants a red-leaved green-leaved lettuce estimated. Lettuce was grown applying low-volume hydroponics closed artificial agroecosystems. positive effect Si used as microadditive freshly harvested biomass established thirtieth day...
In city farming, when growing green crops, a significant part of the production cost is electricity for lighting. The physiology, biochemistry, morphology and productivity plants can be affected by changing irradiation modes these changes reduce costs. However, results studies in literature are contradictory. this work, we investigated effect impulse (frequency 1000 Hz duty cycle 67%), scanning (the principle running lights) constant 16 h 24 operation white light LED irradiators on...
Plant pathogens are an important agricultural problem, and early rapid pathogen identification is critical for crop preservation. This work focuses on using fluorescence spectroscopy to characterize compare healthy fungal pathogen-infected wheat grains. The excitation–emission matrices of whole grains were measured a spectrometer. samples included control manually infected with Fusarium graminearum Alternaria alternata fungi. five distinct zones identified by analyzing the location peaks at...
This research is aimed at the assessing impact of ultraviolet radiation in A, B, and C ranges (as additives to main light) on general plan condition, stress experienced by them, pigment concentration leaves leaf reflective characteristics. Under studying, there were photo-protective reactions purple variety basil plants. The plants grown plastic pots a phyto-chamber equipped with an automatic microclimate system. was divided into four compartments where, addition lighting, installed...
The present research is focused on various pine ecotypes’ seed reproduction in the chalky substrate, challenging environmental conditions carbonate soils chalk outcrops south of Central Russian Upland relation to woods re-afforestation. winter and spring sowing methods were studied, along with a pre-seeding treatment, by biopreparations based consortium Glomales fungi, bacteria genus Bacillus, bioactive substances. seeds two ecotypes, Pinus sylvestris L.; var. cretacea Kalenicz exKom,...
Investigation is devoted to the optimization of light spectrum and intensity used for red mustard growing. Notably, most studies growing were conducted on micro-greens, which not enough development methods recommendations making right choices about irradiation parameters full-cycle cultivation. In this study, we tested four models LED with different ratios blue, green far radiation intensity: 12:20:63:5; 15:30:49:6; 30:1:68:1, in two values photon flux density (PFD)—120 180 µmol m−2 s−1—to...
Due to widespread selenium deficiency in food the aim of this study was evaluate effectiveness a new Se(II)-containing organic chemical compound 2-iminoselenazolidin-4-ones (ISeA) form nanoscale associate (1–5 nm) solution for Swiss chard and komatsuna plants biofortification. Application chosen substance as foliar treatment (2 mg·L−1) an additive hydroponic nutrient (10 performed. Both cultures had high level Se absorption, distribution accumulation leaves two or more times greater than...
Annotation It is known that far red light not a source of photosynthetic energy, but affects the adaptation and development processes plants. Most these studies are conducted on young plants, it important to understand how high-beam biochemical composition tomato fruit, which determines taste useful properties. The effect long-range radiation morphological parameters plant grown under artificial irradiation with LEDs different ratio from 2 9 same spectral in range 400÷700 nm was studied....
The effect of oxygen dissolved in water was researched (1.3 mg/l – without saturation, 6.1 air 14.7 saturation) on the microgreen productivity “Ivolga” variety wheat and ‘Aida’ lentils. It found that enrichment for seed germination with stimulates speedy receipt lentils sprouts 1 day faster than variant saturation. An increase concentration contributes to rapid root system growth cultures, formation 2 order roots, accelerates development overhead plant parts dry weight loss. On 7th...
