Germination accelerating method beneficial to dormancy breaking of seeds of Sorbus tianschanica Ruper

Abstract

The invention belongs to the technical field of germination accelerating and breeding, and particularly relates to a germination accelerating method beneficial to dormancy breaking of seeds of Sorbustianschanica Ruper. The germination accelerating method mainly comprises the steps of collecting fruits, then refrigerating the fruits, carrying out dormancy breaking, and then sowing seeds. Accordingto the method, the seeds do not need to be continuously turned over, a large amount of manpower and material resources are saved, the seeds are not directly washed out after being collected, the obtained seeds cannot rot or mildew after being treated, the influence of use of a pesticide on the root system of Sorbus tianschanica Ruper in a traditional method is overcome, and later seedling emergence is facilitated; and in the whole germination accelerating process, observation of the white bud exposing process of the seeds is facilitated, time-consuming and labor-consuming operation such as seed coat stripping is not needed, and damage to the seeds is avoided.

Description

technical field [0001] The invention belongs to the technical field of germination acceleration and breeding, and in particular relates to a germination acceleration method that is beneficial to breaking dormancy of Sorbus australis Tianshan seeds. Background technique [0002] Tianshan Sorbus, deciduous shrub or small tree, odd pinnate compound leaves, clustered on short branches, usually 11-15 leaflets, ovate-lanceolate, apex acuminate, elegant and clean leaves. Tianshan Sorbus has strong cold resistance, leaves fall early in late autumn, and its flowers, fruits, and leaves have high ornamental value. It is a precious ornamental tree species in Tianshan Mountains of Xinjiang. The dry twigs and leaves of Tianshan Sorbus are unique folk herbal medicines in Xinjiang, and their fruits, twigs, leaves and stem bark are used as medicine. Its fruit tastes sweet and bitter, flat in nature, tender branches, leaves and stem bark taste bitter, non-toxic, has the effects of clearing a...

AI Technical Summary

Problems solved by technology

Tianshan Sorbus is a tree species that is difficult to germinate, and the seeds have strict requirements on germination conditions, and the germination rate is low

At present, there are two methods for breaking dormancy of Sorbus seeds: one is to use chemical treatment and combine wet sand for low-temperature stratification. Partially generate heat, causing the seeds to rot and become moldy; at the same time, due to the use of conventional chemicals, the roots of the rowan will grow and turn brown locally, which is not conducive to seedling emergence; Peeled seeds are placed in a petri dish and placed in a light incubator for cultivation

The disadvantage of this method is that it takes time and effort to peel off the seed coat artificially, and in the process of peeling off the seed coat, it is very easy to cause seed damage
