Abstract:
In this research, to develop a geometric micromodel of grape tissue, the cell growth model based on the biomechanics of plant cells was used. Based on this, the cells were considered as a closed polygon that consists of thin elastic walls under tension of the turgor pressure inside the cell. In the built model, to determine the position and velocity of the vertices of the cell walls and, as a result, the position of the cell at any time, the system of governing differential equations was solved. By comparing the geometric characteristics of the tissue obtained from the cell growth model with the actual grape tissue, the variables of the model were optimized. The results showed the compatibility of the geometric parameters extracted from the tissue created by the cell growth model with the values obtained from the real grape tissue with a coefficient of determination of 0.995. The cellular structure created from the grape tissue can be used to simulate the transfer phenomena caused by applying processes on the grape, growth modeling, simulation of the cracks created on the grape berries, or modeling the expansion of these cracks during growth.
