Problems solved by technology

However, due to the large amount of sand used in the low-temperature sand layering process, it is difficult to control the defect at low temperature, and the humidity of the sand is difficult to control evenly. When the layering time is as long as several months, the operational feasibility is poor.

Embodiment

[0024] 1 Test materials and methods

[0025] 1.1 Materials

[0026] Both Junqianzi and Begonia fruits were collected at the teaching practice base of the School of Horticulture and Landscape Architecture of Henan University of Science and Technology - Guguzhai Base, Xinxiang County. On December 5, 2016, the fruits of Junqianzi and Begonia were picked, which were fully mature, free from diseases and insect pests, and could fully represent the characteristics of this variety. The collected fruits were piled up until the fruits were decomposed and softened, rubbed off the pulp, washed the seeds, dried naturally and stored in a low-temperature refrigerator (2-5°C) for more than 24 hours for later use. Qianzi and Begonia were treated with low-temperature sand stratification and low-temperature water stratification, respectively, and the low-temperature blank was placed as a control, and the progress of the stratification was not checked regularly.

Abstract

The invention provides a novel layering method for breaking dormancy of arbor seeds, and belongs to the technical field of plant seed cultivation. The invention provides a novel stratification method adopting low-temperature water stratification treatment. The method is to place arbor seeds in sterile water and perform stratification treatment at a low temperature of 2-5° C. for 53-81 days. The low-temperature water stratification treatment method provided by the invention can effectively break the deep dormancy characteristics of arbor seeds, and significantly improve the germination characteristics of the seeds. The seeds of Junqianzi and ornamental crabapple seeds are used as test materials for low-temperature water stratification treatment, and the germination rate and germination rate The potential average is higher than the traditional low-temperature sand stratification method, and the shortest stratification time for low-temperature water stratification treatment is only 53 days, which is 7 days shorter than the 60-day period for sand stratification treatment, which can effectively replace the traditional Low-temperature sand storage layered, and has the characteristics of simple, safe and hygienic.

Description

technical field [0001] The invention belongs to the technical field of plant seed cultivation, and in particular relates to a novel layering method for breaking dormancy of arbor seeds. Background technique [0002] Seed germination is the basis of crop growth, an important link and turning point in the life cycle of seed plants, the starting point for the growth and development of higher plants, and an important characteristic for plants to adapt to environmental changes to maintain their own reproduction. Seed germination is directly related to ecological processes such as species reproduction, population maintenance, expansion and recovery, and also directly affects the distribution, dynamics and diversity of vegetation. However, due to the limitation of the seed coat and the influence of the existing state of internal nutrients, plant seeds generally have physiological dormancy. [0003] Seed dormancy refers to the phenomenon that mature and viable seeds cannot germinat...
