Abstract


In this paper are presented results regarding the physiological behavior of some local populations of Capsicum annuum ssp. grossum, cultivated compared to the control variety Cornel on sandy soils from the Research and Development Station for Plant Culture on Sands, Dăbuleni. The researches focused on the effects of thermal stress on the processes of photosynthesis and foliar transpiration, as well as on the productions made in pepper culture. The results obtained underlined the importance of correlating the physiological processes in pepper plants with environmental factors and the yields obtained. Under conditions of heat stress, all local populations analyzed showed values of photosynthesis above the values recorded at the control variant (Cornel variety). The water lost through foliar transpiration was efficiently recovered by the studied local populations, between transpiration and pepper production being established a positive correlation, significant from statistically point of view.
