Chronic Contamination

This study analyzes the effects of acetaminophen (APAP) as a contaminant on physiological characteristics of lettuce plants (Lactuca sativa L.). Experiments were provided in an experimental greenhouse with semi-controlled conditions. The effect of different amounts of contaminant was evaluated by using regression analysis. Plants were grown in five concentrations of APAP: 0 µM, 5 µM, 50 µM, 500 µM, and 5 mM for 14 days in two variants, acute and chronic. The obtained results show that the monitored parameters were demonstrably influenced by the experimental variant. Plants are more sensitive to chronic contamination compared to acute. Significant (p < 0.05) deviation in photosynthesis and fluorescence was observed compared to the control in different variants. The highest doses of APAP reduced the intensity of photosynthesis by a maximum of more than 31% compared to the control. A reduction of 18% was observed for the fluorescence parameters. Pronounced correlation was described between chlorophyll fluorescence parameters and yield mainly under APAP conditions. The amount of chlorophyll was influenced by exposure to APAP.

A number of morphophysiological parameters of the candidate crop Lactuca sativa L. for growing in space after influence of the combined action of proton irradiation and clinostating were assessed. It was found that the effect of simulated space conditions reduces the surface area of leaf blades, the mass of roots and shoots of lettuce plants, was not change the number of true leaves. After 20 days of cultivation of L. sativa after irradiation and clinostating, the values of the parameters of the length of shoots, roots, and chlorophyll fluorescence were at the level of control plants. The results obtained contribute to the development of space crop production. Key words: GROWING PLANTS IN SPACE, SALAD CROPS, SOWED LETTUCE, IRRADIATION, PROTONS, STRESS, CLINOSTAT
