Abstract

The invention belongs to the technical field of seed treatment and particularly relates to a Thuja sutchuenensis seed treatment method for increasing germination rate; the method comprises the specific steps of (1) selecting Thuja sutchuenensis seeds that are full with no worm stings, soaking the seeds in potassium mercuric iodide solution having a mass fraction of 0.2-0.4% for 34-38 min, taking out, and freezing for 25-27 min to obtain pretreated Thuja sutchuenensis seeds; (2) treating the pretreated Thuja sutchuenensis seeds via steam in vacuum for 12-14 min, soaking in a germination accelerating liquid for 26-30 min, ultrasonically treating with ultrasonic wave, draining, and taking out treated Thuja sutchuenensis seeds; (3) subjecting the treated Thuja sutchuenensis seeds to germination acceleration at 38-40 DEG C under relative humidity of 65-70%, and irradiating with orange light during germination acceleration. The method of the invention has the advantages that the ability of Thuja sutchuenensis seeds to germinate is effectively improved, and the condition of Thuja sutchuenensis being endangered is relieved.

Description

Technical field [0001] The invention belongs to the technical field of seed treatment, in particular to a method for treating Thuja cypress seeds with improved germination rate. Background technique [0002] Thuja is a unique evergreen tree of the Cupressaceae family Thuja, with a height of up to 20 m, which has important academic value and prospects for development and utilization. In April 1892, the French missionary Fargos was established in Chengkou County, Chongqing. Thuja was discovered for the first time in the limestone mountains of Bashan. In the following 100 years, people have visited the producing area many times, but the species was not found. The first volume of the Red Book of Chinese Plants and the fourth volume of the English version of the Flora of China (gymnosperm) designated it as an extinct species in the wild; in 1999, when the Chongqing Forestry Bureau organized experts to conduct a survey of national key protected wild plants , The species was rediscover...
