Problems solved by technology

The production of Canadian Bauhinia mainly uses seeds for propagation, but the seeds have obvious dormancy habits, which brings a lot of inconvenience to seed quality inspection and field sowing

example 1

[0016] In the quality inspection of seeds, in order to make the seeds of Bauhinia canadensis germinate smoothly, it is necessary to release the physical and physiological dormancy of the seeds first. To release the physical dormancy of the seeds, that is, to release the impact of the dense seed coat on the water absorption of the seeds. Therefore, in principle, any method that can improve the permeability of the seed coat can be selected. But in actual use, there are still various problems. This example uses the method of cutting off the end of the cotyledon to make a detailed description of how to release the dormancy of Bauhinia canadensis seeds and perform a quality inspection of the seeds.

[0017] A method for quickly testing the quality of Bauhinia canadensis seeds, which is to cut the seed coat (remove the end of the cotyledon), soak the seeds with gibberellin after imbibition method: use a single-sided blade to cut the seed coat of the seed, because the seed coat is ha...

Embodiment 2

[0022] With reference to the method of Example 1, by further optimizing the experiment, the fully imbibed seeds were treated with 450-550mg L -1 gibberellin solution, soak the seeds for 20-24 hours, the germination rate is the highest, and the test effect is the best. Use absorbent cotton as a germination bed, and the germination bed needs to be replaced frequently to prevent the polluted germination bed from affecting seed germination. The germination substrate is sterilized river sand, and care should be taken to keep the river sand moist during seed germination. After changing the germination bed many times, the germination bed is not polluted, and the seeds can germinate smoothly, such as figure 2 shown.

[0023] Therefore, this method can be used for rapid inspection of seed quality. It is simple and fast to operate, and can complete the release of seed dormancy and make it germinate in a relatively short period of time. It provides an efficient and reliable technology...

Abstract

The invention discloses a method for quickly testing quality of cercis canadensis seeds. The method comprises the following steps of: firstly, cutting seed coats open; secondly, placing the seeds in a germination bed which is laid with absorbent cotton to absorb water slowly until the seeds are sufficiently imbibed; thirdly, soaking the sufficiently imbibed seeds in a 450-550mg.L<-1> gibberellin solution for 20 to 24 hours; and finally placing the seed in an illuminating incubator at the temperature of 25 DEG C, culturing for 14 days, and checking germination of the seed. The method can be operated simply and quickly, ensures that the seeds are released from dormancy and germinate in a short time, is a highly efficient and reliable technology for testing the quality of the cercis canadensis seed before planting and seedling raising, has a broad application prospect and high practical application value, and can produce good economic and social benefits.

Description

technical field [0001] The invention relates to a method for inspecting seed quality, in particular to a method for quickly inspecting the quality of Canadian bauhinia seeds. Background technique [0002] Canadian redbud (Cercis canadensis L.), Hemataceae, Bauhinia genus, native to the eastern United States, ranging from New Jersey and western Pennsylvania in the northern United States to southern Michigan and southeastern Nebraska, south to Texas and Florida State. The leaves of Bauhinia canadensis are heart-shaped, and the new leaves are light reddish purple, and then gradually turn dark green with luster. Before the leaves fall in autumn, the leaves are golden, orange, and purple, with sharp contrast and extremely beautiful. Canadian Bauhinia blooms first in early spring. The corolla is flat, round, reddish-purple, clustered or in racemes, and the flower clusters are luxuriant and eye-catching. It is a famous ornamental plant. The flowers of Canadian redbud are edible ...
