Problems solved by technology

The above two methods use ethephon and gibberellin hormones respectively in the process of seed treatment, especially the latter uses GA 3 The concentration is as high as 100g / L, which may destroy the hormone level in the seeds, resulting in abnormal phenomena such as excessive growth after emergence, and this method is inconvenient to operate, and the germination time of the seeds is long

Abstract

The invention discloses a method for simply and quickly breaking agriophyllum squarrosum seed dormancy. The method comprises the following steps of seed collection and impurity removal, seed treatment, germination experiment and result statistics, wherein the step of seed treatment comprises seed preservation, water separation, prepriming and seed coat breakage; the prepriming is characterized inthat seeds obtained by water separation are put into a beaker, then, distilled water is added, the breaker is put in a preset illumination incubator, the illumination incubator is set to be 30 DEG C for as eight hours and 10 DEG C for sixteen hours, illumination is set to be completely dark, the beaker is taken out in every 3 to 5 hours, the distilled water is poured, the seed is washed by the distilled water for 2 to 6 minutes, then, the distilled water is added, the beaker is put into the incubator again, and the operation is repeated for 4 to 8 times; the germination experiment is characterized in that the obtained seed of which the seed coat is broken is repeated for four times, 50 seeds are repeatedly put in a 9-cm culture dish on which filter paper is laid each time, 5ml of distilledwater is added, the seeds are cultured under a completely dark condition in the illumination incubator, and illumination incubator setting is the same with the prepriming. The method has the advantages of short germination time, high sprouting rate and good young seedling quality.

Description

technical field [0001] The invention relates to the technical field of raising seedlings of the mobile sand dune pioneer plant Amyrrha sativa, in particular to a method for accelerating the germination of the seeds, specifically a simple and fast method for breaking the dormancy of the Amygrhiza sativa seeds. Background technique [0002] Shami ( Agriophyllum squarrosum ) belongs to Chenopodiaceae (Chenopodiaceae) and Agriophyllum (Agriophyllum). It is a pioneer plant of mobile dunes and is widely distributed in various sandy areas in northern my country; it not only has good wind and sand resistance, but also has rich seeds. Food that people like. In recent years, some scholars, through the preliminary analysis of the nutritional components needed by the human body and their bioactive components such as SOD, chlorogenic acid, saponins, isoflavones, alkaloids, etc., believe that sand rice is a natural functional food, especially suitable for children. and the elderly to eat...
