OLEAtool: An open-source software for morphopalynological research in Olea europaea L. pollen.

Area of Science:

• Palynology
• Image Analysis
• Botanical Research

Background:

• Olive tree (Olea) pollen analysis is crucial for understanding Mediterranean cultivation history.
• Distinguishing wild from cultivated olive varieties using traditional methods is challenging.
• Morphological analysis of pollen grains is often time-consuming and difficult.

Purpose of the Study:

• Introduce OLEAtool, a novel software tool for Olea pollen research.
• Facilitate and improve the efficiency of morphological analysis and measurements of Olea pollen.
• Enhance the replicability and scope of pollen analysis in palynological studies.

Main Methods:

• OLEAtool is developed as a macro extension for ImageJ, a free image analysis software.
• The tool is designed for morphological analysis and measurements of Olea pollen grains.
• Integrated into the OLEA-project for studying olive tree expansion on the Balearic Islands.

Main Results:

• OLEAtool significantly increases the speed of data collection for pollen analysis.
• The software expands the range of measurable variables for pollen morphology.
• Enhanced replicability of morphological analysis is achieved with OLEAtool.

Conclusions:

• OLEAtool offers a substantial improvement for palynological research on Olea pollen.
• The tool addresses limitations in traditional methods for olive pollen analysis.
• OLEAtool contributes to more efficient and reliable studies of olive tree cultivation and history.
