A Germination Accelerating Method Favorable for Breaking Dormancy of Sorbus tianshanensis Seeds

Abstract

The invention belongs to the technical field of germination acceleration and breeding, and in particular relates to a germination acceleration method which is beneficial to breaking dormancy of Sorbus australis Tianshan seeds. The method for accelerating germination mainly collects and refrigerates the fruit, breaks dormancy, and then sows. The method provided by the invention does not require continuous replanting, saves a lot of manpower and material resources, and does not directly wash out the seeds after the seeds are collected. After the treatment, the obtained seeds will not rot and mold, and overcome the traditional methods. The impact of the use of the chemical agent on the root system of rowan is beneficial to the emergence of seedlings in the later stage; during the whole germination process, it is convenient to observe the seed whitening process, and there is no need to perform time-consuming and laborious operations such as peeling off the seed coat, and will not cause damage to the seeds.

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
