Plant Phenotyping Equipment in India for Physiology and Stress Research
Plant physiology asks how a plant functions: how much water it uses, how it regulates its stomata, how efficiently it photosynthesises and how all of that changes under stress. Plant phenotyping equipment turns those questions into numbers that can be compared across many plants, genotypes and treatments.
JKG BioScience supplies and supports plant phenotyping systems from Plant-DiTech and photosynthesis and light-measurement instruments from Photon Systems Instruments (PSI). Pair them with our controlled-environment chambers to get both halves of a physiology experiment right: repeatable conditions and precise measurement.
What you can measure
- Whole-plant transpiration and water-use efficiency
- Biomass gain and growth rate
- Stomatal conductance through the day
- Chlorophyll fluorescence and photosynthetic performance
- Root-zone and atmospheric conditions per plant
- Light intensity and spectral quality

Plant-DiTech
PlantArray: Gravimetric Plant Phenotyping System
PlantArray continuously and simultaneously measures the water flux between soil, plant and atmosphere for every plant in an array. Each plant sits on its own load-cell lysimeter, so transpiration, water-use efficiency and biomass gain are measured directly while the system controls irrigation plant by plant. Treatments can be compared quickly and non-invasively, with drought-stress phenotyping experiments completed in weeks rather than a full season.
How it works
- Control: two self-controlled valves per unit for plant-specific feedback irrigation
- Measure: load-cell weighing plus an environment logger for temperature, humidity, PAR, VPD and pressure
- Analyse: SPAC-Analytics with real-time ANOVA and t-tests
- Units work independently, so one fault does not stop the array

Add-ons
Complete the PlantArray System
SPAC-Analytics
Cloud software tracking weight, soil water content, daily transpiration, biomass gain, water-use efficiency, stomatal conductance and relative water content, with real-time statistics.
MultiFerti add-on
Eight controllers run eight fertigation treatments from separate tanks, with flushing between treatments and EC, temperature and volume sensing.
Sensors add-on
Soil moisture, temperature and EC; air conditions; PAR; NDVI; canopy temperature; soil oxygen; and water depth, EC and pH.
Flood Control Kit
Automated flood events that lower soil oxygen, alone or combined with salinity or nutrient treatments.
Photon Systems Instruments
Chlorophyll Fluorescence and Light Measurement
Chlorophyll fluorescence is a fast, non-invasive window into photosynthesis. Changes in Fv/Fm, the OJIP transient or non-photochemical quenching reveal stress before symptoms are visible. PSI instruments range from pocket-sized pens to imaging systems.
FluorPen and PAR-FluorPen
Handheld chlorophyll fluorometers for the lab, greenhouse and field: Ft, QY (Fv/Fm), OJIP, NPQ and light curves. The PAR version adds a light sensor.
FluorCam imaging
Pulse-amplitude-modulated chlorophyll fluorescence imaging across leaves and whole plants, from handheld and closed units to open and customised systems.
SpectraPen and PlantPen
SpectraPen measures light spectrum and PAR; PlantPen measures NDVI and PRI reflectance for plant vigour and stress.
Selection guide
Drought Stress Phenotyping and Other Stress Studies
Start from the stress you want to study. This table shows what to control and measure, and which equipment fits.
| Stress | What to control and measure | Equipment |
|---|---|---|
| Drought | Hold a defined drought stage; measure transpiration, water-use efficiency, biomass and stomatal conductance; follow photosynthetic response | PlantArray with SPAC-Analytics; FluorPen or FluorCam |
| Salinity | Apply salt treatments and gradients; track soil EC, growth and transpiration | PlantArray with MultiFerti and Sensors add-on |
| Flooding and low oxygen | Apply controlled flood events, alone or with salinity or nutrients | PlantArray with Flood Control Kit |
| Nutrients and biostimulants | Run several fertigation treatments in one experiment | PlantArray with MultiFerti |
| Heat and cold | Hold set temperatures and photoperiods; follow photosystem II efficiency | JKG Universal Series or Percival chambers with FluorPen or FluorCam |
| Light quality and quantity | Define intensity and spectrum; measure what plants receive | LED growth chambers with SpectraPen |
Controlled conditions
Pair Phenotyping with Growth Chambers
Physiology data are only as good as the conditions they were collected in. JKG Universal Series and Percival chambers hold set temperature and photoperiod, with options for humidity, CO₂, dimmable LED lighting and extended temperature ranges. PlantArray fits most greenhouses and growth rooms; tell us your space and pot size and we will plan the layout.

FAQ
Frequently Asked Questions
Answers to the questions we hear most. Can’t find what you need? Our team will help.
What is plant phenotyping equipment?
Instruments and systems that measure plant traits such as water use, growth rate, stomatal conductance and photosynthetic efficiency, so that genotypes and treatments can be compared objectively. Gravimetric platforms such as PlantArray, chlorophyll fluorometers and imaging systems are common examples.
What is gravimetric plant phenotyping?
Each plant sits on its own load cell, which records weight continuously. Changes in weight give transpiration, water-use efficiency and biomass gain for every plant, without disturbing it.
Can PlantArray run drought and salinity treatments at the same time?
Yes. Each control unit has its own valves, so different irrigation, fertigation, salinity or flood treatments can run side by side in one experiment.
Which chlorophyll fluorometer should I choose?
FluorPen suits quick, handheld measurements of single leaves in the lab, greenhouse or field. FluorCam images fluorescence across whole leaves or plants and supports full quenching and OJIP analysis.
Can phenotyping run inside a growth chamber?
Yes. PlantArray and FluorCam work in greenhouses, growth rooms and chambers. Tell us the chamber dimensions and pot size and we will advise on the layout.
What does a plant phenotyping system cost in India?
Cost depends on the number of plants, pot size, add-ons and sensors. Share your experiment design and we will prepare a configuration and quotation.
Do you provide installation, training and support?
Yes. JKG installs and commissions the systems it supplies, trains your team and provides ongoing support.
