Germination accelerating method for platycodon grandiflorus seeds

Abstract

The invention relates to the technical field of floriculture, specifically to the technical field of platycodon grandiflorus breeding. A germination accelerating method for platycodon grandiflorus seeds is characterized in that: placing the platycodon grandiflorus seeds in magnetized water containing salicylic acid with a concentration of 0.07-0.6 mmol/L and immersing for 4 hours, taking out and drying, placing in magnetized water again for 4 hours, repeating for 5 times, and the total immersing time is 20 hours; wherein the immersing temperature of the magnetized water is 25-28 DEG C, the drying is that adsorbing the water on the surface of each seed by filter paper and spreading the seeds on the wet filter paper in a room for 2 hours, the magnetized water takes clear water as a water source and is obtained by passing through a water magnetizer with magnetic induction intensity of 0.2-0.7 T in a flow velocity of 1 m/h, and the seed-immersing culture is carried out in a incubator. The germination for platycodon grandiflorus seeds has advantages in that: germination energy of the seeds and germination percentage of the seeds are both substantially improved by using germination accelerating method provided by the invention, and the growth of adventitious roots is substantially enhanced by adding salicylic acid into the magnetized water, and the germination accelerating method is beneficial to a survival rate of large-scale sowing as well as a survival rate of conventional transplanting.

Description

technical field [0001] The invention relates to the technical field of flower cultivation, in particular to the technical field of platycodon grandiflorum propagation. Background technique [0002] The perennial root herb of Campanulaceae Campanulaceae, perennial dicotyledonous herb, also known as Baiyao, monk head, monk hat, bag flower, four-leaf vegetable, bell flower, hexagonal lotus, bitter root vegetable, stalk grass, Baiyao, native ginseng, Korean ethnic group Platycodon grandiflorum, which is called "Doraki", is native to all parts of my country, and likes a warm, sunny, cool and humid environment. Natural platycodon grandiflorum is mostly born on hillsides, among grasses or beside ditches. Campanulaceae is a deep-rooted plant, a perennial herbaceous perennial flower, mostly wild in the grass on the hillside, its roots are fat and fleshy, cylindrical, unbranched or less branched. The main production is in Bozhou, Anhui and other places, and in the Yimeng mountainous a...
