The question of application of sources of light on light-emitting diodes in hothouses is considered. The necessity of devel-
opment of complex for registration of bioelectric potentials of plants, necessity for working off technology of growing of
plants with the use of lamps on light-emitting diodes is grounded. The developed measuring complex allows to influence on
vegetable bioobjects with LED (laser) SOR and to estimate the response in real time. Size of BEP reflects real processes of
a metabolism and is inseparably linked with a physiological condition of a live organism, and the steady nonequilibrium
state in vegetable organisms is supported due to processes of a metabolism continuously proceeding in them. Thus, at re-
search of various ways of stimulation of development of VBO measurement of size BEP can be used for an assessment of a
functional condition of VBO at different stages of an organogenesis. References 3, figures 2.
Key words: vegetable bioobject, bioelectronic potential, diagnostics, LED (laser) light source.
Statement of the problem. Modern development in semiconductor branch allows to make inexpensive highly
effective LED and laser sources of optical radiation (SOR), that are differing in high light return and big service life.
Big advantage of light-emitting diode and laser sources of optical radiation is possibility of obtaining monochromatic
radiation practically in any part of a range. Advantage of laser sources of optical radiation is coherence of radiation.
Semiconductor sources of optical radiation are applied more actively in plants of the closed soil, that is caused not only
by obtaining monochromatic radiation in phytoactive part of a range, but also by low power consumption and low ther-
mal emission, that gives the chance to establish light-emitting diodes (laser diodes) near vegetable bioobjects (VBO)
without risk of their damage.
Modern light-emitting diodes (laser diodes) use all visible range of an optical spectrum. Range radiation waves
lengths of semiconductor sources of optical radiation in red area of a spectrum is 620-780 nm, in orange – 600-620 nm,
in yellow – 585-595 nm, in green – 500-570 nm, in pale blue – 465-490 nm and in dark blue – 430-465 nm. Thus, mak-
ing combinations of light-emitting diodes (laser diodes) of different range of radiation, it is possible to receive a source
of optical radiation with almost any spectral structure in the visible range.
Spectral maxima of absorption of a chlorophyll "a" vegetable bioobject coincide with 410,2; 430,8 and 656,3 nm
lines; red maxima of a chlorophyll “b” coincide with 640 and 649,5 nm lines; phytochrome – with 381,6; 396,8 and 656,3 nm
lines. The greatest quantity of maxima of absorption of functionally different pigments the strip with width 390-440 nanome-
ters possesses. The green range isn't absolutely necessary for ensuring photosynthesis, but thanks to the high penetration is
useful to ensuring photosynthesis optically dense leaves and dense crops of vegetable bioobjects [2]. Therefore in a LED (la-
ser) source some colors can be combined, that block these phytoactive sites. However, the question of an optimum combina-
tion of light-emitting diodes (laser diodes) of certain range of radiation isn't solved yet, and there is a set of recommendations
about this occasion, differing from each other.
Analysis of recent research. At present producers of LED production offered a wide choice of the LED phy-
tolamps, differing by the power, a percentage ratio of applied light-emitting diodes of a certain range and, respectively,
the general range of radiation. According to results of researches [3] the optimum structure of radiation has the follow-
ing ratio of energy on a range: 30% − dark blue spectrum, 20% − green spectrum, 50% − red spectrum. However, light-
emitting diodes of a green range in industrial samples of phytolamps practically aren't applied. The relation of a light
stream of red and dark blue light in the majority of the LED lamps calculated on ensuring good photosynthesis of plants
during various period of their growth, varies in the wide range: 9:5, 6:3, 11:5, 7:1, 8:1 and 9:1. In the same time not
enough attention is paid by producers of phytolamps to coherent SOR – lasers though they found a wide circulation for
example in preseeding processing.
The formulation of article purposes. For definition of an optimum ratio of quantity of light-emitting diodes
(laser diodes) a different range, of influence of coherence of radiation on activity of vegetable bioobjects, for research
of influence of operating modes of LED (laser) SOR on them , and also for the purpose of providing the best conditions
for receiving ready for goods, it is necessary to develop a technique and the measuring complex, that allow LED (laser)
SOR to influence on vegetable bioobjects and allow to estimate response in real time.
The main part. The majority of the experiments, that are made for the purpose of studying of influence on
VBO of these or those factors, are estimated by results of end products (viability, energy of germination, productivity)
which can't be connected unambiguously with their influence that demands additional eliminating experiments and that
is extremely inefficient from the power and temporary point of view. The optimum decision is the analysis of instant

reaction of VBO on external influence. For a small period it is difficultly to observe direct reaction of vegetable bioob-
jects to these influences, however it is possible to fix the bioelectric potential (BEP) of cells.
Bioelectric polarity of VBO is expressed in distinctions of metabolic potentials between separate bodies, tis-
sues, cells in a stable permanent state. Size of BEP reflects real processes of a metabolism and is inseparably linked
with a physiological condition of a live organism, and the steady nonequilibrium state in vegetable organisms is sup-
ported due to processes of a metabolism continuously proceeding in them. Thus, at research of various ways of stimula-
tion of development of VBO measurement of size BEP can be used for an assessment of a functional condition of VBO
at different stages of an organogenesis.
Pulse bioelectric activity characterizes changes in func-
tional activity of vegetable bioobjects and that activity is the an-
swer to changes in environment and answer on influences of irritat-
ing factors. Pulse electric activity divides on three types: the action
potentials (AP) - pulse electric answers to supraliminal stimulus;
the variable potentials which are reaction of the highest VBO on
damaging, or high-energy influences; microrhythms is a type of
rhythmic pulse electric activity in VBO [1].
Active capacity of big group of cells (vegetable tissue) can
be measured by contact of electrodes with different points of VBO,
where the bioelectricity is measured. In this case the observed sig-
nal occurs because of cellular polarization-depolarization.
Now complexes for measurement of electric activity of
VBO aren't made. The devices developed by efforts of certain researchers, are difficult in operation and demand special
conditions and high qualification of the personnel.
Existence of such complex for measurement of BEP of vegetable bioobjects will allow studying the interrela-
tion characteristic "the radiation system – object of radiation" and will give the chance to fulfill technology of cultiva-
tion of VBO with application of LED (laser) SOR that in its turn will allow to increase growth of ready goods and to
reduce energy consumption.
For studying of influence of LED (laser) SOR on VBO development of the complex including lighting installa-

tion on ultrabright light-emitting diodes of green, blue and red ranges of radiation (or the block of laser diodes of the
corresponding range), the block of registration of BEP and the computer that is intended for collecting, displaying and
the analyzing of received information is supposed (fig. 1).
By means of the control unit and the pulse-width modulation it can be carried out both regulation of intensity
of the general optical stream and change of spectral structure due to adjustment of intensity of radiation of light-
emitting diodes (laser diodes) in various color ranges, than influence on МBO is provided (fig. 2). Also, the spectral
structure can be changed and in the discrete way, changing quantity of SOR of the certain range participating in process
of radiation that gives the chance to define their exact ratio.
BEP of vegetable bioobject arrives on an entrance of the tool amplifier, further on an entrance of the block of
the analog-digital converter after what the digital signal arrives on the computer for further processing and the analysis
of influence of operating modes and spectral structure of radiation of LED (laser) SOR on vegetable bioobjects.
Conclusions. The creation of electrotechnological system of control on influence of electromagnetic fields of
optical range on vegetable bioobjects will allow:
− to define an optimal range and power of optical radiation of semiconductor sources at their influence on vegeta-
ble bioobjects at different stages of development;
− to develop power effective, ecologically safe agrotechnology of processing vegetable bioobjects electromag-
netic fields of optical range reaction considering them to radiation with the subsequent regulation of its range and power.
