AB  - The delayed chlorophyll fluorescence method, as a non-invasive bioluminescence method, is recommended for the application in maize breeding and seed production in order to evaluate maize inbred lines for their resistance and adaptability to increased and high temperatures, as well as, to drought. The flowing thermal properties of the photosynthetic apparatus of the observed maize inbred lines: the temperature dependence within a range of 25-60oC, critical temperatures at which phase transitions occur in the thylakoid membrane were discovered and by means of its significant functional changes in the photosynthetic apparatus of observed maize inbred lines were detected. activation energies (Ea, kJ mol-1) alongside the straight lines prior and after critical temperatures were calculated. Ea are a measure of occurrence of chlorophyll DF recombination processes and by that a measure of the total changes in structure and functioning of the thylakoid membranes. Thylakoid membranes underwent significant conformational changes in the part following the maximum intensity, i.e. in the part of its sharp linear decline. Such a state fits more to a nonliving than a living organism in relation to its both, structure and functions. Results and the discussion of presented parameters of total thermal processes of chlorophyll DF, such as: temperature dependence, critical temperatures and activation energy, can be an important factor for a more exact characterization of maize inbred lines in relation to their resistance and adaptation to temperature and drought, contributing to a rapider and more rational development of the selection process.
AB  - Utvrđene su termalne karakteristike fotosintetičnog aparata proučavanih samooplodnih linija kukuruza, i to: određena je temperaturna zavisnost u opsegu od 25 do 60 °C, otkrivene su kritične temperature na kojima dolazi do faznih transformacija u tilakoidnoj membrani, obračunate su energije aktivacije (Ea, kJ/mol) duž pravih linija pre i posle kritične temperature. Ea je mera nastajanja rekombinacionih reakcija povezanih sa uspostavljanjem zakasnele fluorescencije (ZF) hlorofila, a time i ukupnih promena u strukturi i funkciji tilakoidnih membrana. Rezultati i diskusija izloženih parametara ukupnih terminalnih procesa ZF hlorofila, kao što su: temperaturna zavisnost, kritične temperature i energija aktivacije, mogu doprineti egzaktnijem karakterisanju samooplodnih linija kukuruza u odnosu na njihovu otpornost i adaptivnost prema temperaturi i suši. Sve ovo doprinosi egzaktnijem, bržem i racionalnijem odvijanju procesa selekcije.

AB  - Thermal processes of delayed chlorophyll fluorescence (DF) within an intact leaf segment of inbred lines of maize (Zea mays L.) within the temperature range of 24-60°C were studied. The method for chlorophyll DF measurements is non-invasive and was developed in order to study the connection between bioluminescence and photosynthesis. Two maize inbreeds (ZPPL 52 and ZPLK 132), that are considered to have a scientific and professional value in breeding, were observed. Obtained results on the temperature dependence of chlorophyll DF indicated that the inbred ZPPL 52 is more resistant to temperatures. The first temperature effect in this inbred was observed at 34°C, while the maximum chlorophyll DF intensity is registered at 60°C. The corresponding estimates in the inbred ZPLK 132 were detected at 31.5°C and 52.0°C, respectively. The air drought treatments of the inbred ZPLK 132 lowered the stated temperatures to 30.5°C, i.e. 47.5°C, respectively. Conformational changes were observed in thylakoid membranes of studied maize inbred lines. The obtained changes were determined by the number and the grade of critical temperatures. There were four critical temperatures in each of the studied inbreeds, while there were five critical temperatures in the inbred ZPLK 132 under air drought treatment. Different levels of activation energy (Ea, kJ mol-1) for chlorophyll DF thermal processes varied from -21,7 and -22.00 to 241.44 kJ mol-1. The values of Ea obtained in observed maize inbred lines differ over the number, sign and magnitude. Negative Ea values were detected in all cases of chlorophyll DF intensity increases with the temperature increase, which was established for the first time. Such values of Ea are explained by conformational changes in chlorophyll molecules and by their reactivity. Results and discussion of presented parameters of total thermal processes of chlorophyll DF (temperature dependence, critical temperatures and activation energy), can be an important factor for a more exact characterisation of maize inbred lines in relation to their resistance and adaptation to temperature and drought, contributing to a more rapid and rational development of the selection process.
