What Is Petiole Pro?

Petiole Pro is a plant phenotyping application designed for agricultural researchers, students, and growers who need to collect plant measurements from images captured on smartphones. The application works as a digital measurement tool for analyzing plant characteristics such as leaf area, leaf parameters, leaf greenness, germination rates, and seed quality.

Users can capture plant images using a smartphone camera, process the images through the application, and save measurement data for research or field analysis. Petiole Pro also supports offline measurement workflows, allowing users to collect data in locations without internet access.

What Is Petiole Pro Best For?

Petiole Pro is best known for its smartphone-based leaf area measurement capability, which users value for replacing manual measurement methods with a faster field-ready workflow. The app allows researchers and growers to capture plant images, process them, and measure leaf area without dedicated laboratory equipment.

Its offline functionality and ability to collect measurements directly in field conditions make it useful for plant phenotyping studies where portability and quick data collection are important. Petiole Pro’s leaf area measurement feature supports these workflows with image-based analysis and calibration tools

Petiole Pro Integrations

Petiole Pro does not publicly disclose third-party software integrations.

How Does Petiole Pro Work?

Petiole Pro follows a smartphone-based measurement workflow that converts plant images into measurable data. Here's a step-by-step breakdown:

Install the Petiole Pro app and prepare a calibration pad before starting measurements
Place the leaf or plant sample on a calibration surface with visible reference markers
Capture an image using a smartphone camera while keeping the sample and markers visible
Process captured images through Petiole Pro to calculate plant measurements automatically
Measure traits such as leaf area, leaf length, leaf width, greenness, and object counts
Record measurement results directly within the app for future reference and analysis
Compare plant data across varieties, treatments, growth stages, and environmental conditions
Collect field data offline without requiring continuous internet connectivity during measurements

Petiole Pro Use Cases

Based on our analysis of Petiole Pro's current capabilities, we identified several scenarios where the platform is a strong fit:

1. Crop Researchers Measuring Leaf Area Across Large Sample Sets

Plant scientists handling dozens or hundreds of leaf samples in field or lab conditions face time-consuming manual measurement using traditional tools like flatbed scanners or ImageJ. Petiole Pro's Leaf Area Meter measures leaf area, length, width, and diameter from a smartphone photo. In turn, it reduces measurement time from minutes per leaf to seconds, with results exportable directly from the field without returning to a lab.

2. Agronomists Monitoring Nitrogen Status Without A SPAD Meter

SPAD chlorophyll content meters are expensive and not always available in the field. Petiole Pro's Leaf Nitrogen/Chlorophyll Meter computes the Dark Green Color Index (DGCI) from a smartphone photo. This gives agronomists a portable, low-cost alternative for estimating nitrogen status and identifying deficiencies across crops without carrying specialized equipment.

3. Seed Quality Teams Running Germination Assessments

Seed producers and researchers assessing germination rates across multiple trays face slow, error-prone manual counting. Petiole Pro's Germination Count uses AI to quickly assess seed germination, predict crop emergence, and support planting strategy decisions. This reduces the time required to process large seed batches in quality assurance workflows.

4. Small Fruit Growers Estimating Berry Yield Before Harvest

Strawberry and blueberry growers estimating yield ahead of harvest typically rely on visual inspection — an inconsistent method that makes supply planning difficult. Petiole Pro's Berry Counter counts strawberry flowers and fruits, and blueberries, from a smartphone photo while also estimating fruit size and weight. As a result, fruit growers are given growers data-driven yield estimates without additional equipment.

5. Potato Producers Grading Crop Quality Against USDA Standards

Manual potato grading is time-consuming and inconsistent across operators. Petiole Pro's Seed QA and Potato AI tools use AI-powered mobile grading to evaluate potato quality with USDA compliance. This enables real-time data sharing across teams and reduces grading inconsistencies that lead to rejected or downgraded produce.

Is Petiole Pro Right For You?

Petiole Pro is suited for agricultural researchers, universities, students, and growers who need smartphone-based plant measurement tools for field and laboratory studies. It helps users analyze traits such as leaf area, leaf greenness, germination, and seed quality through image-based workflows. The platform has been referenced in 95 published research papers across journals such as MDPI Plants, Environmental and Experimental Botany, Frontiers in Plant Science, bioRxiv, European Journal of Forest Research, and more.

Petiole Pro Features

Leaf Greenness Measurement

Petiole Pro measures leaf greenness by analyzing leaf images and calculating the DGCI. Users capture leaves with a color calibration reference, allowing the app to estimate changes in plant color. This feature supports studies that monitor plant nitrogen status, chlorophyll levels, and overall plant health.

See How It Works

Germination Counting

The platform uses image analysis to count germinated seeds from photographs of seed trays. Users capture an image of the tray, define the analysis area, and process the image within the application. The feature helps researchers record germination rates and monitor seed development during plant experiments.

See How It Works

Seed Quality Assessment

Petiole Pro supports seed quality analysis by allowing users to evaluate seeds through smartphone images. The application processes captured images to measure seed-related characteristics and organize observations. This workflow helps researchers and agricultural professionals assess seed samples during experiments, breeding programs, and quality evaluation processes.

See How It Works

Offline Plant Data Collection

The tool allows users to collect plant measurements without requiring continuous internet access. Researchers can capture images and record plant data directly in field environments where connectivity may be limited. This supports outdoor studies, crop monitoring, and experiments that require measurements outside controlled laboratory settings.
