A few days ago, the LCpro photosynthesis instrument and the FluorPenFP100 chlorophyll fluorescence instrument purchased by our company through the crop institute of Hebei Academy of Agricultural and Forestry Sciences passed the acceptance and put into use.
The above is the use of LCpro photosynthesis instrument and FP100 fluorometer to measure the photosynthesis of wheat in the test field.
In recent years, chlorophyll fluorescence technology has become ubiquitous in the study of plant physiology and ecology. Without chlorophyll fluorescence data, field photosynthesis data of plants are no longer complete photosynthesis research data. With the development of portable fluorometers, this trend has become more apparent in the research field (Kate Maxwell et al., 2000).
The LCPro-SD portable photosynthesis meter is an intelligent portable photosynthesis meter used to measure the photosynthetic rate, transpiration rate, stomatal conductance and other parameters related to plant photosynthesis. The instrument uses IRGA (infrared gas analysis) CO2 analysis module and dual laser tuning fast response water vapor sensor to accurately measure the changes of CO2 concentration and moisture on the leaf surface to investigate the photosynthesis related parameters of the leaf and plant. The artificial light source, CO2 control unit and temperature control unit can precisely regulate the environmental conditions at the same time, thereby measuring the effects of light intensity, CO2 concentration and temperature on the plant photosynthetic system. This instrument can be used in harsh environments such as high humidity and high dust, and has wide applicability.
The measurement parameters include photosynthesis rate, transpiration rate, intercellular CO2 concentration, stomatal conductance, leaf temperature, leaf chamber temperature, photosynthetic effective radiation, air pressure, etc., and photoresponse curve and CO2 response curve measurement can be performed.
FluorPen FP100 hand-held chlorophyll fluorometer is used for rapid measurement of plant chlorophyll fluorescence parameters in the laboratory, greenhouse and field. It has the characteristics of strong portability, high accuracy and high cost performance; two-key operation, with graphic display, built-in lithium battery and data storage, It is widely used to study plant photosynthesis, stress monitoring, herbicide detection or mutant screening, and can also be used for biological detection of ecotoxicology, such as chlorophyll fluorescence response of different plants to soil or water pollution to find sensitive plants as organisms. The sensor is used for biological detection. FP100 is equipped with a variety of leaf clip models for different samples and research.
FluorPen measurement parameters include F0, Ft, Fm, Fm ', QY_Ln, QY_Dn, NPQ, Qp, Rfd, RAR, Area, M0, Sm, PI, ABS / RC and more than 50 chlorophyll fluorescence parameters, and 3 light-emitting programs Light response curve, two kinds of fluorescence quenching curves, OJIP fast fluorescence kinetics, Kautsky induction effect, etc.
Zarco-Tejada, etc., used LCPro photosynthesis instrument, FluorPen handheld chlorophyll fluorometer, PolyPen400 plant spectral reflectance measurement instrument, combined with UAV remote sensing technology to study the field photosynthesis evaluation and its application in precision agriculture , The research results were published in Remote Sensing of Environment (Seasonal stability of chlorophyll fluorescence quantified from airborne hyperspectral imagery as an indicator of net photosynthesis in the context of precision agriculture. Remote Sensing of Environment, 2016)
