The studies were carried out in 2024, starting from April and ending in October, in the Tesna Gorges and Stan's Peak Natural Reserves from the Domogled-Cerna Valley protected area. The processes targeted were photosynthesis, transpiration and leaf respiration. Also, were determined: cell sap concentration, osmotic pressure of mesophyll cells, total leaf water content, free and bound water.
The intensity of the photosynthesis process was determined in the year 2024 in each month of the vegetation period to make the seasonal variation graphs. After analyzing these graphs, it was found that the photosynthesis process recorded a maximum in June, followed by a reduction in the intensity of the process, although it was normal to remain at high values until the time of fruiting. The reduction in photosynthesis was due to very high temperatures associated with very low soil moisture.
The total reduced leaf water content recorded since July indicated a negative water balance caused by the very low amount of available water.
