Abstract

The invention provides a method for improving seed shattering of lolium multiflorum seeds, and relates to the technical field of crop breeding. According to the method, in the later growth period of the Italian ryegrass, by spraying the exogenous substance gibberellin and/or glyphosate, the seed shattering rate and the empty shrunken rate of the Italian ryegrass seeds can be remarkably reduced, the thousand seed weight is increased, and the seed quality is improved.

Description

technical field [0001] The invention relates to the technical field of crop breeding, in particular to a method for improving the shattering performance of Lolium multiflora seeds. Background technique [0002] Grass seed shattering refers to that after the seed matures, affected by the changes in the peripheral organs of the seed, the joint between the base of the spikelet and the parent inflorescence breaks, and the seed is loosely wrapped in the glume, and gradually decreases with the water content. When it is opened, the seeds scatter to the ground. Grain shattering widely exists in the plant kingdom, and it is an adaptive mechanism formed during the long-term competition and evolution of plants. However, shattering will cause losses to agricultural and animal husbandry seed production. A large number of seeds fall off naturally before harvesting, which increases the cost of seed production and seriously affects the quality and yield of seeds. Due to the short cultivat...
