AB  - Standard induction processes of delayed fluorescence (DF) of chlorophyll (induction signals) occur when an intact leaf segment of maize inbreds and hybrids is kept in the phosphoroscope darkroom for more than 15 minutes (t > 15 min), and at the same time the leaf is illuminated with the intermittent white light. Resolved induction processes of DF chlorophyll into transients: A, B, C, D and E occur when the intact leaf segment of maize inbreds and hybrids is kept in the phosphoroscope darkroom for a significantly shorter period (500 s > t > 30 s), with the time rate t of 30 s, prior to its illumination with the intermittent white light. Induction transients: A, B, C, D and E are characterized with the time of their generation: tA = 31±6 ms (A), tB = 5 ± 0,5 s (B), tC = 15±5 s (C), tD = 360±20 s (D) and tE = 670±35 s (E), dynamics of changes in transients intensities (IA, IB, IC, ID and IE) and mechanisms of their generation. The induction processes of chlorophyll DF of the intact leaf of maize inbreds and hybrids resolved into transients: A, B, C, D and E are accompanied by the occurrence and different levels of activation energy (Ea, kJ mol-1) that correspond to critical temperatures ranging from 28 to 33°C. The generation mechanisms of induction transients A, B, C, D and E classify them into two groups. Transients A and B are of a physical character, while the transients: C, D, and E are of a chemical character. It is shown that the generation of the induction transients: B, C, D and E simultaneously follows establishing of the oscillations of induction processes of the DF chlorophyll. Oscillating of induction processes of DF chlorophyll is explained by the ion (K+, Na+, H+, Cl-) transport mechanism across the thylakoid membrane of the intact leaf of maize inbreds and hybrids grown under conditions of air drought, increased temperatures and water deficiency in the medium.

Međuzavisnost oscilacija i indukcionih tranzijenata: A, B, C, D i E javlja se kod intaktnih listova linija (ZPR 70ž i Oh 43) i hibrida (ZPDC 360, ZPSC 46A, ZPSC 704 i ZPSC 71) kukuruza koji su gajeni u staklari u uslovima različite vazdušne suše, delovanja viših temperatura i deficita vode u podlozi. Posebno se ukazuje na uslove pri kojima dolazi do uspostavljanja standardnih indukcionih procesa ZF hlorofila. Daje se kraći opis standardne indukcione krive ZF hlorofila.

AB  - The obtained results confirm the hypothesis that there are maize elite inbred lines (ZPPL 62 and ZPPL 233) that are considered prestigious and are characteristic by their water status and a greater rate of a dry down during the grain maturation. Also, they are characteristic by their efficient photosynthetic-fluorescence photo-model, which is successfully used in the contemporary technological productions of maize hybrid seed. The presented results on the dynamics of grain dry down during the maturation period and on photosynthetic and fluorescence parameters: temperature dependency of the intensity of delay chlorophyll fluorescence, the Arrhenius plot for the determination of critical temperatures (phase transition temperatures), activation energy and the angle between the ear leaf and the stalk of the maize plant, show that traits of observed inbreds are mainly based on good effects and nature of conformational and functional changes that occur in their thylakoid membranes and other chemical structures of grain and leaf tissue. Some other properties of observed prestigious maize inbred lines relevant to the seed production were also analyzed in this study.

AB  - The application of the improved non-invasive photosynthetic-fluorescence method in maize breeding and seed production was observed in order to assess the resistance and adaptability of maize inbred lines to higher and high temperatures, as well as to drought. The studies were carried out with two maize inbred lines (ZPPL 115 and A 671). The thermal characteristics of the photosynthetic apparatus of the investigated maize inbred lines were determined as follows: temperature dependency range from 25 to 60oC, critical temperatures at which phase transitions take place in the thylakoid membrane, causing significant structural and functional changes in the photosynthetic apparatus of the investigated inbred lines, activation energies (Ea, kJ/mol) were calculated along the straight lines before and after the occurrence of the critical temperature. The activation energy (Ea) is a measure of the intensity of recombining responses to chlorophyll DF, and total changes in the structure and functioning of the thylakoid membranes. The results obtained and presented parameters of total photosynthetic and thermal processes of chlorophyll DF may contribute to a more accurate characterisation of maize inbred lines in respect to their resistance and adaptability to temperatures and drought. Consecutively, this can lead to a quicker and more rational improvement maize breeding and seed production.
AB  - Poboljšani neinvazivni fotosintetično-fluorescentni metod kandiduje se za primenu u oplemenjivanju i semenarstvu radi utvrđivanja ocene samooplodnih linija kukuruza na plastičnost, tolerantnost, otpornost i adaptivnost prema višim i visokim temperaturama, kao i prema suši. Utvrđene su termalne karakteristike fotosintetičnog aparata proučavanih samooplodnih linija kukuruza, i to: određena je temperaturna zavisnost u opsegu od 25 do 60oC, otkrivene su kritične temperature na kojima dolazi do faznih transformacija u tilakoidnoj membrani, a time i do značajnih strukturnih i funkcionalnih promena u fotosintetičnom aparatu ispitivanih samooplodnih linija kukuruza, obračunate su energije aktivacije (Ea, kJ/mol) duž pravih linija pre i posle pojavljivanja kritične temperature. Energija aktivacije (Ea) je mera nastajanja rekombinacionih reakcija povezanih sa uspostavljanjem ZF hlorofila, a time i ukupnih promena u strukturi i funkciji tilakodinih membrana.

abstract = "The application of the improved non-invasive photosynthetic-fluorescence method in maize breeding and seed production was observed in order to assess the resistance and adaptability of maize inbred lines to higher and high temperatures, as well as to drought. The studies were carried out with two maize inbred lines (ZPPL 115 and A 671). The thermal characteristics of the photosynthetic apparatus of the investigated maize inbred lines were determined as follows: temperature dependency range from 25 to 60oC, critical temperatures at which phase transitions take place in the thylakoid membrane, causing significant structural and functional changes in the photosynthetic apparatus of the investigated inbred lines, activation energies (Ea, kJ/mol) were calculated along the straight lines before and after the occurrence of the critical temperature. The activation energy (Ea) is a measure of the intensity of recombining responses to chlorophyll DF, and total changes in the structure and functioning of the thylakoid membranes. The results obtained and presented parameters of total photosynthetic and thermal processes of chlorophyll DF may contribute to a more accurate characterisation of maize inbred lines in respect to their resistance and adaptability to temperatures and drought. Consecutively, this can lead to a quicker and more rational improvement maize breeding and seed production., Poboljšani neinvazivni fotosintetično-fluorescentni metod kandiduje se za primenu u oplemenjivanju i semenarstvu radi utvrđivanja ocene samooplodnih linija kukuruza na plastičnost, tolerantnost, otpornost i adaptivnost prema višim i visokim temperaturama, kao i prema suši. Utvrđene su termalne karakteristike fotosintetičnog aparata proučavanih samooplodnih linija kukuruza, i to: određena je temperaturna zavisnost u opsegu od 25 do 60oC, otkrivene su kritične temperature na kojima dolazi do faznih transformacija u tilakoidnoj membrani, a time i do značajnih strukturnih i funkcionalnih promena u fotosintetičnom aparatu ispitivanih samooplodnih linija kukuruza, obračunate su energije aktivacije (Ea, kJ/mol) duž pravih linija pre i posle pojavljivanja kritične temperature.
