Dieser bezieht sich auf die Studie welche sich im Anhang befindet. Durch einen Vorgang der Halopriming genannt wird, im Grunde nur ein Einweichen von Samen in einer Salzlösung über Nacht, wird die Keimrate von vielen Arten stark erhöht, vor allem bei üblichem Gartengemüse und Getreidearten wie Reis und Weizen.
Abstract
Seed priming improves the seed performance and also helps the seedlings to alleviate the detrimental effects of various stresses.
Seed priming is believed to bring about some biochemical changes in the metabolism within the seed, which ultimately favors germination
and the further growth stages of the seedlings even under stressed conditions. The present investigation was carried out to
study the effect of hydropriming and halopriming in three rice varieties (Neeraja, Vaisakh, and Vytilla 6), with varied abiotic stress
tolerance potential under NaCl and PEG stress. In general, the application of both stresses, NaCl and PEG induced retardation of
growth and metabolism of the seedlings. However, seed priming treatments could reduce the extent of decrease in these biological
attributes. Both hydro- and halopriming resulted in the enhancement of protein, carbohydrate, and photosynthetic pigment content,
modulated antioxidant enzyme activities, reduced the lipid peroxidation of biomembranes, and enhanced the photochemistry and
mitochondrial activities in rice seedlings subjected to NaCl and PEG stress as compared to non-primed ones. According to the various
morphological, physiological, and biochemical characteristics studied in the rice seedlings raised from primed and non-primed
seeds, we confirmed that both hydropriming and halopriming had a positive influence on stimulating metabolism in rice seeds, which
ultimately resulted in improved seedling vigor and tolerance under NaCl and PEG stress. Halopriming was found to be more efficient
than hydropriming in enhancing the seedling vigor, overall growth, and stress tolerance potential of rice varieties.
