Embodiment 1
[0018] When sowing seedlings in the field, in order to enable the seeds of Dahua Sizhaohua to germinate smoothly, it is necessary to release the dormancy of the seeds. This example uses the method of gibberellin treatment combined with low-temperature stratification to describe in detail how to release the dormancy of the seeds of Sizhaohua grandis.
[0019] A method to promote seed dormancy of Dahua Sizhaohua: use 500mg·L -1 The seeds were soaked with gibberellin for 72 hours, and then the treated seeds were stratified at 0-5°C for 90 days.
[0020] The specific test plan and results are shown in Table 1.
[0021] Table 1 Germination rate of seeds treated with gibberellin combined with low temperature stratification
[0022]
[0023] Note: Germination rate: the ratio of the number of seeds that germinate and have the potential to become normal seedlings to the total number of seeds tested.
[0024] It can be seen from the results in Table 1 that soaking seeds with 500 m...
Embodiment 2
[0026] When sowing seedlings in the field, in order to make the seeds of Dahua Sizhaohua germinate smoothly, it is necessary to remove the dormancy of the seeds, especially the physical dormancy of the seeds, that is, to remove the influence of the bony seed coat on the water absorption and air permeability of the seeds, and promote the seeds to grow faster. to sprout. In principle, any method that can improve the permeability of the seed coat can be used. But in actual use, there are still various problems. This example uses concentrated sulfuric acid acid etching method to describe in detail how to promote the germination of Dahua Sizhaohua seeds.
[0027] A method for promoting the germination of Dahua Sizhaohua seeds is a method of acid etching with concentrated sulfuric acid, soaking seeds with gibberellin and then using low-temperature stratification: first, treat Dahua Sizhaohua seeds with concentrated sulfuric acid for 10 minutes, and keep stirring during the treatmen...
