The QTLs controlling germination and early seedling growth were mapped using seeds acquired from mapping population and parental lines of Chinese Spring and SQ1 grown under water-limited conditions, severe drought SDr and well-watered plants C. Early seedling growth was evaluated on the basis of the length of the root and leaf at the 6th day of the experiment. For the traits studied, a total of thirty eight additive QTLs were identified.
The results indicate the complex and polygenic nature of germination. This is a preview of subscription content, log in to check access. Austin R. Eds , Plants under stress.

QTL mapping for germination of seeds obtained from previous wheat generation under drought
PL EN. Widoczny [Schowaj] Abstrakt. Adres strony. Day and night in plant life. Life of organisms, their physiological responses and developmental processes are determined by day and night length which varies with seasons and is a driving force of the biological clock. The photomorphogenic processes are influenced by light intensity, quality and direction. Different photomorphogenic processes, such as seed germination, flowering and phototropism induced by the relative day and night length require absorption of light by specialized photoreceptors such as phytochromes, cryptochromes, phototropins.
Abscisic acid is one of the plant hormones that determines normal growth and development, i. An appropriate level of endogenous ABA plays a key role in the regulation of most of these processes. Its content in a particular tissue is a balance between the rate of its biosynthesis, oxidative degradation and formation of inactive derivatives mainly ester. The progress on ABA metabolism was relatively slow in the past. Application of modern molecular biology methods let the most of genes encoding enzymes involved in the regulation of ABA metabolism be identified and contributed to the understanding of its action.
