AI Technical Summary

Problems solved by technology

Because the seeds of Codonopsis verticillum are very small, the thousand-grain weight is only about 1.5g; the seeds have strong dormancy, and the germination rate after sowing is low under natural conditions, which restricts the large-scale artificial cultivation of Codonopsis verticillum

Embodiment

[0015] Experimental Materials

[0016] Gibberellin (content 75% powder), produced by Shanghai Tongrui Biotechnology Co., Ltd.; ethanol is analytically pure; for the test Codonopsis pilosula seeds.

[0017] Experimental method (in two phases)

[0018] Solution preparation

[0019] Take 7 beakers, wash and dry them, and mark the concentration values. According to the corresponding concentration requirements, weigh 50mg, 100mg, 150mg, 250mg, 350mg, and 450mg of gibberellin, respectively, into a beaker, and add a small amount of ethanol to stir. Finally add water to make up to 500mL.

[0020] The first stage

[0021] The Codonopsis verticillum seed is divided into 63 parts, every part 200, packs with gauze respectively and then loads successively concentration and is respectively 0mg / L (ck), 100mg / L, 200mg / L, 300mg / L, 500mg / L, Soak in a beaker of 700mg / L and 900mg / L gibberellin solution for 12 hours, take it out and rinse it with clean water; take 63 petri dishes, wash and dr...

Abstract

The invention discloses a method for increasing the germination rate of condonpsis lanceolata seeds. The condonpsis lanceolata seeds are treated with 300-500 mg / L of gibberellins under 18-25 DEG C temperature change condition. Preferably, the condonpsis lanceolata seeds are treated with 300 mg / L of gibberellins at 25 DEG C under the dark condition for 24 h. The condonpsis lanceolata seeds are treated with gibberellins, the dormancy characteristic of seeds is broken through, and large-area artificial planting of condonpsis lanceolata is made possible.

Description

technical field [0001] The invention relates to the technical field of seed treatment, in particular to a method for improving the germination rate of Codonopsis verticillum seeds. Background technique [0002] [Odonopsis lanceolatae (Sieb.et Zucc) Trautv.] belongs to the platycodonaceae Codonopsis genus perennial herbaceous vines, also known as mountain carrot, four-leaf ginseng, mountain melon, goat milk, is a precious Chinese medicinal material in Changbai Mountain, and is also a food. Medicinal and dual-purpose plants. Distributed in Northeast China, North Korea, Japan, and Russia, it grows wild on the edge of mountain forests, under woods, between bushes and valleys. The root is used as medicine, sweet in taste and flat in nature. It is a commonly used medicine for invigorating the middle and nourishing qi, and has anti-aging, anti-oxidation, anti-fatigue, and anti-tumor effects[. Codonopsis verticillum is rich in nutrients such as vitamins, amino acids, and trace ele...
