Embodiment 1

[0014] Example 1: A method for promoting the germination of arborina japonica seeds, comprising the steps of:

[0015] (1) After the seeds are harvested from the end of October to the beginning of November in autumn, rinse and remove the empty and shriveled seeds, and soak the full seeds in 4% NaOH solution at 30-40°C to remove the oil on the surface of the seed coat and rinse them with clean water dry in the shade, spare;

[0016] (2) Mix the seeds of step (1) with clean wet sand at a volume ratio of 1:1 and knead until the enamel layer on the surface of the seeds is destroyed and burrs, and then mix the burred seeds and wet sand evenly at a volume ratio of 1:2 , the humidity of the wet sand should be such that no water can be squeezed by hand, and it is ready for use;

[0017] (3) Put the seeds of step (2) in a greenhouse with a temperature of 25°C and a humidity of 80% for 30 days. During this period, spray 50% carbendazim wettable powder diluted 800 times for disinfecti...

Abstract

The invention discloses a method for promoting germination of cornus florida l. seeds, and belongs to the plant breeding technical field. The method includes the steps: (1) blending the seeds; (2) treating seed coat mechanical impairing; (3) storing the seeds with sand; and (4) accelerating germination of the seeds after hormone treatment. After the cornus florida l. seeds are treated through a dormancy breaking method, the cornus florida l. seed germination rate reaches 95.7%.

Description

technical field [0001] The invention relates to a plant breeding technology method, in particular to a method for promoting the germination of arboria multiflora seeds. Background technique [0002] Multiflora wood ( Comus Florida L. ), also known as Dahua Sizhaohua and American Huamizuki, is a small deciduous tree in the Cornaceae family. It is native to eastern North America. The orange-red stone fruit does not fall through the winter. It is an excellent ornamental and oil-bearing tree species with broad market prospects. my country is still in the stage of introduction trials. The seeds of A. multiflora have high oil content, hard seed coat, and seeds have dormancy characteristics. Some domestic scholars have studied that the seeds of A. multiflora have not been treated, and the germination rate of the seeds in that year is almost zero. The germination rate of short-term low-temperature sand storage treatment The germination rate is less than 50%, and it needs 360 days ...
