Problems solved by technology

[0005] Many of the current studies use concentrated sulfuric acid or gibberellin to accelerate germination, but most of them have to be stratified, and there is no literature report on the treatment of sumac seeds with concentrated sulfuric acid and gibberellin, such as Yuan Yaqi et al. Effects of treatments on seed germination of lacquer trees from three provenances" ("Economic Forest Research", 2017, 35(3)), Tang Li et al. No. 10), Yang Weize, etc. "The Effects of Different Treatment Methods on the Germination of Sumac Seeds" (Anhui Forestry Science and Technology, 2014, 40(6): 30-33)

Embodiment 1

[0028] The impact of different solution treatments of embodiment 1 on Japanese wild sumac seed germination

[0029] Select mature and plump Japanese wild sumac seeds, soak and disinfect with 50% carbendazim 500 times solution for 1 hour, then wash and drain with clean water. Use washing powder solution, baking soda solution and concentrated sulfuric acid (that is, 98% H 2 SO 4 ) solution to soak the seeds, the dosage should be 1cm higher than the seeds, and keep stirring to make the medicine fully contact with the seeds. Set up test group 1, test group 2, test group 3 and blank group, with 30 seeds in each group, repeated 3 times. Test group 1 was treated with concentrated sulfuric acid for 25 minutes, test group 2 was treated with 1% baking soda solution for 12 hours, and test group 3 was treated with 1% washing powder for 12 hours. The blank group was soaked in water for 24 hours. Pour off the medicament solution after treatment, place it under flowing tap water for 30 m...

Embodiment 2

[0033] The different concentrations and time of embodiment 2 concentrated sulfuric acid treatment are on the influence of Japanese wild sumac seed germination

[0034] Select mature and plump Japanese wild sumac seeds, soak and disinfect with 50% carbendazim 500 times solution for 1 hour, then wash and drain with clean water. Then adopt the concentrated sulfuric acid treatment of different concentration and time, establish test group 1, test group 2, test group 3, test group 4, test group 5, test group 6 and test group 7, every group 30 seeds, repeat 3 times. Among them, the test group 1 is 60%H 2 SO 4Treat seeds for 30 minutes, test group 2 is 60% H 2 SO 4 Treat seeds for 60 minutes, test group 3 is 60% H 2 SO 4 Treat seeds for 90 minutes, test group 4 is 98% H 2 SO 4 Treat seeds for 10 minutes, test group 5 is 98% H 2 SO 4 Treat seeds for 15 minutes, test group 6 is 98% H 2 SO 4 Treat seeds for 20 minutes, test group 7 is 98% H 2 SO 4 Treat the seeds for 25 minu...

Embodiment 3

[0038] Embodiment 3 Different concentrations of gibberellin are treated on the impact of Japanese wild sumac seed germination

[0039] Early stage and concentrated sulfuric acid treatment are all carried out according to the method of test group 6 in embodiment 2, then soaked with gibberellin solution, establish test group 1, test group 2, test group 3 and blank group, 30 capsules in each group, repeat 3 times . Test group 1 soaked seeds in 200mg / L gibberellin solution for 12 hours, test group 2 soaked seeds in 300mg / L gibberellin solution for 12 hours, test group 3 soaked seeds in 400mg / L gibberellin solution for 12 hours, and blank group soaked seeds in clear water 12 hours. Rinse under running water after treatment. Then put the seeds in the light incubator, set the temperature of the incubator at 20°C, the photoperiod is 16h / 8h light-dark reaction, the light intensity is 3500Lx, check the ventilation every day, keep the seeds moist, observe and count the germination rate...

Abstract

The invention discloses a method for improving the rhus succedanea seed germination rate and accelerating germination. The method comprises the following steps that (1) ripe and full rhus succedanea seeds are selected to get peels removed and disinfected, and then the treated seeds are dipped with 98% concentrated sulfuric acid for 20-25 minutes so as to accelerate germination; and (2) the seeds obtained in the step (1) are dipped with a gibberellin solution with the concentration being 300mg / L for 12 hours, the seeds are washed cleanly under flowing water after being treated, and the cultureconditions are controlled to conduct germination acceleration. The method can omit the steps of long-time seed soaking and stratification treatment, rapidly breaks seed dormancy of rhus succedanea, effectively improves the seed germination rate, and the germination rate is as high as 98% or above. Meanwhile, the germination time is greatly shortened, the seeds can germinate completely after about7-10 days, the purpose of rapid gemination acceleration is achieved, germination is tidy and consistent, and operation management such as seedling transplanting and field planting in the following period is facilitated.

Description

technical field [0001] The invention belongs to the technical field of plant seed germination pretreatment, in particular, relates to a rapid germination method for sowing and raising seedlings of Japanese wild sumac, especially relates to a method for treating Japanese wild sumac seeds with concentrated sulfuric acid combined with gibberellin to break dormancy and increase germination rate And reach the method for rapid germination. Background technique [0002] Japanese wild sumac (Toxicodendron succedaneum) is a deciduous tree or small tree of the family Anacardiaceae (Toxicodendron). Japanese wild lacquer has a beautiful tree shape, bright red and beautiful autumn leaves, dense branches, and pure colors. It is an excellent landscaping tree species. At the same time, because of its strong adaptability, resistance to drought and barrenness, and well-developed root system, it is also an excellent soil and water conservation tree species. Japanese wild sumac is an excellen...
