Abstract
Tomatoes contain up to 90-95% water, and their yield and quality are highly dependent on water resources.
The vascular system is the primary channel for hydraulic and mineral nutrient transport.
The vascular system plays a crucial role in balancing and distributing water and nutrients between reproductive and nutrient organs under varying hydraulic conditions.
Therefore, under the increasing threat of drought, quantifying the vascular system of different tomato cultivars under water deficit conditions across multiple growth periods is beneficial for understanding the mechanisms of water regulation in tomatoes in response to drought.
This study aims to develop a methodology for quantifying the internal vascular structure of tomato fruits by MRI methodology.
This will enable a comprehensive investigation of fruit water balance strategies at the plant level.
Magnetic resonance imaging (MRI) is a groundbreaking method used to quantify vascular tissues.
Due to its high sensitivity to water, MRI allows for non-destructive 3D visualization and quantification of the internal vascular bundles of tomato fruits. 3D reconstruction of tomato vascular tissues provides numerous parameters, such as vascular tissue exchange surface area, total vascular tissue length, total vascular cross-sectional area, and the number of vascular bundles.
These data will be used to enhance model parameters and contribute to further simulation of fruit hydraulic distribution.
Exploring the genetic variety of fruit vascular structures under water deficit conditions could provide a new breeding label and contribute to the development of water use strategies.
