Photosynthesis measurement technology, chlorophyll fluorescence technology, and UAV remote sensing technology comprehensive application case

A new generation of LCpro T photosynthetic equipment settled in China
Attachment: Photosynthetic measurement technology, chlorophyll fluorescence technology, and UAV remote sensing technology comprehensive application case
In the middle and late March, spring blooms, ADC's new generation of intelligent photosynthetic instrument LCpro T passed the acceptance test of Shanxi Agricultural University, and will soon be put into scientific research and application.
 
The above picture shows the training of teachers and students of Shanxi Agricultural University
 
Above is the LCpro T on the left and the LCi T on the right.

The new generation L Cpro T features are as follows
  • Lighter - the total weight of the main unit and handle is less than 5 kg
  • GPS - record longitude, latitude, altitude data anytime, anywhere
  • Endurance - the new lithium-ion battery life up to 16 hours
  • Screen - excellent performance on touch screen and strong light
  • Control - illumination, temperature, humidity, CO2 four-factor gradient control
  • Leaf chamber - optional wide leaf chamber, narrow leaf chamber, conifer chamber, Arabidopsis leaf chamber, canopy measurement chamber, soil breathing chamber, etc.

LCPro-T is an intelligent portable photosynthesis measuring instrument for measuring plant photosynthesis, transpiration rate, stomatal conductance and other parameters related to plant photosynthesis. The instrument uses IRGA (infrared gas analysis) CO2 analysis module and dual laser tuned fast response water vapor sensor to accurately control environmental conditions through artificial light source, CO2 control unit and temperature control unit to determine light intensity, CO2 concentration and temperature on plant photosynthetic system. Impact. This instrument has a wide range of applicability and can be used in harsh environments such as high humidity and high dust.
Measurement parameters include photosynthetic rate, transpiration rate, intercellular CO2 concentration, stomatal conductance, leaf temperature, leaf chamber temperature, photosynthetically active radiation, gas pressure, etc., and can be used to measure the light response curve and CO2 response curve.
[Case 1] SCI District 1
V. Gonzalez-Dugo et al. used a combination of UK ADC's LCpro photosynthetic apparatus, crop canopy temperature monitoring technology and UAV remote sensing technology (equipped with hyperspectral imaging and infrared thermal imaging sensors) to evaluate multiple citrus orchards using the water stress index CWSI. The temporal and spatial dynamics of tree species were published in the 2014 Agricultural and Forest Meteorology (SCI Zone 1, IF 5.035).
The above table shows the results of measuring the leaf temperature, transpiration rate, stomatal conductance and photosynthetic rate of plants by photosynthetic apparatus.
 
Figure A above shows hyperspectral imaging of canopy-scale target species, and B is the canopy reflection spectrum, showing significant differences in 2011 and 2010.
 
The above picture shows the changes in Crop Water Stress Index (CWSI), A and B are common trees, and C and D are orange trees.

[Case 2] S CI three districts
Sergio Gálvez and others use the LCpro photosynthetic apparatus (for measuring CO2 assimilation rate and stomatal conductance) produced by ADC, PSI Polypen RP400 handheld plant reflectance spectrometer / leaf clip hyperspectrometer (for measuring photochemical reflection) Index PRI, carotenoid index CAR and spectral reflectance curves, etc.) and FluorPen FP100 handheld chlorophyll fluorescence meter (for measuring parameters such as crop steady-state chlorophyll fluorescence), combined with hyperspectral imaging and infrared thermography UAV remote sensing technology, Gene expression analysis, comprehensive study on drought tolerance of wheat variety "Chinese Spring" at leaf level and canopy level. The article is published in the Journal of Functional & Integrative Genomics (2018) (Hotspots in the genomic architecture of field drought responses in wheat as breeding targets).
The above figure shows the comprehensive phenotypic analysis of the gene expression of dehydrin dehydrin and aquaporin gene in the farm sample and leaf scales. SS is severe stress, MS is mild stress, and I is watering. a (left) is the spectral reflectance curve of the crop, a (middle) is the chlorophyll fluorescence fraction fluorescence (F), a (right) is the photochemical vegetation index PRI, and b is the canopy scale crop water stress index Crop Water Stress Index (CWSI) and TEMARI 1510 (Transformed Chlorophyll Absorption in Reflectance Index), C is the expression value of dehydrin (DHN) and aquaporin (AQP)

Sweet Corn Cob

A medium-sized ear of corn provides more than 10% of our daily dietary fiber requirements. Rich dietary fiber can help the body to carry out a rapid metabolism function, but also can make a strong sense of satiety.
The same amount of corn is lower in calories than rice, contains natural rather than added sugar, and is high in fiber, which can help gastrointestinal digestion, and has more vitamins, so it is a good food worth eating more. However, there is a limit to what you eat, and the food that will not gain weight will make you fat if you eat too much, at least, it will not make you thin. It can only be said that relatively speaking, eating corn is much healthier than eating those high-calorie snacks, and it is not easy to gain weight.
Moreover, the large amount of natural vitamin E contained in fresh corn has the functions of promoting cell division, delaying cell aging, lowering serum cholesterol, preventing skin lesions, and reducing the symptoms of arteriosclerosis and brain function decline.
