New equipment acquired – Porometer/Fluorometer

Posted on by

Through a simplified (bargain) procurement procedure, the LI-600PF was acquired – a portable device for the simultaneous measurement of stomatal conductance and chlorophyll fluorescence on the same area of a leaf sample, used within the project for the physiological phenotyping of grapevine. This instrument enables the rapid and non-invasive collection of data on the photosynthetic activity and water status of plants, with results for both parameters available in less than 10 seconds per reading.

A built-in PAR (Photosynthetically Active Radiation) sensor records ambient light at each measurement, while an IRT (Infrared Leaf Temperature) sensor measures leaf temperature, providing a more complete insight into the physiological state of the plant. In addition, the device comes with built-in software for configuring settings, calibration and data processing, as well as a built-in barcode reader, allowing simple and reliable labelling and tracking of individual samples.

Field research – Zrmanja

Posted on by

On two occasions during May and June, members of the project team carried out field research in the area of the Krupa River (a tributary of the Zrmanja) with the aim of locating and collecting samples of wild grapevine (Vitis vinifera subsp. sylvestris).

During the fieldwork, the team members located sites of wild grapevine and collected the plant material needed for further analyses. Each individual plant was labelled with a tag bearing its corresponding code, enabling reliable tracking and unambiguous identification of each plant. All collected material was documented in a way that allows for its subsequent morphological characterisation and genomic analysis, together with the recording of the associated data on the location and habitat of each plant found.
