Abstract
There was studied impact of the bitter almond seeds preliminary steeping on the development of plants at the first stages of development in conditions of saline waters irrigation in the greenhouse experiment ambient in phytotron. It was established that steeping the seeds in excessive salt solution results in enhanced plants tolerance to the soil salinization and saline waters irrigation. This is evidenced by the obtained regularities of influence on the development of plants of biochemical character (content of proline, chlorophyll and carotinoids, total carbon); chemical (content of basic chemical elements); morphological (rate of the plants height and stalk diameter growth, leaf-area duration). The introduction of developed technology into nursery science will permit to improve the tolerance of seedlings to salinization of soils and irrigation waters.
Highlights
Bitter almond (Prunus Amygdalus) is widely used in Egypt as a parent stock for stone fruits [1]
The proposed paper bears the results of experiments to make known the peculiarities of the soils and irrigation waters salinization influence on the first development stages of bitter almond, the seeds of which were preliminarily steeped in saline solution
The seedlings, germinated from the seeds, which were steeped in the high-salt concentration solution (5dsm-1), featured the larger gain in diameter and height, as compared with the treatment by solution with the lower concentration of salts (Table 1)
Summary
Bitter almond (Prunus Amygdalus) is widely used in Egypt as a parent stock for stone fruits [1]. The proposed paper bears the results of experiments to make known the peculiarities of the soils and irrigation waters salinization influence on the first development stages of bitter almond, the seeds of which were preliminarily steeped in saline solution.
