Storage method of lily powder

Abstract

The invention discloses a storage method of lily powder. The storage method comprises the following steps of: (1), preparing a constant-humidity salt solution-sodium nitrite saturated solution; (2), adding the prepared solution to the bottom of a dryer until the liquid surface is 1-2cm away from the porcelain plate of the dryer, sealing for later use, wherein the relative humidity is 60%-70%; (3), filling collected pollen to a gelatin hollow capsule, covering the capsule cover, and puncturing a pore at each of the two ends of the capsule respectively for facilitating gas exchange; (4), placing the capsule filled with the pollen to an envelope or a paper bag, using a paper clip for sealing and placing on the porcelain plate of the dryer, wherein the sealing by a paper clip aims at facilitating gas exchange; and (5), sealing the dryer and placing to a refrigerator of 5 DEG C for storage for a long time. The storage method of the lily powder is simple and easy to implement; and the service life of the lily powder stored by the method can achieve one year or longer.

Description

technical field [0001] The invention relates to a method for storing lily pollen. Background technique [0002] Pollen is the microspore of a flowering plant. When it germinates, it produces a male gametophyte containing three haploid nuclei, which contains all the genetic information of the plant, and is an important material for plant hybrid breeding and germplasm resource preservation. Pollen viability refers to the ability of pollen to survive, grow, germinate or develop, and is one of the key factors for the success of hybrid breeding. Pollen lifespan is the period during which pollen remains viable under certain conditions. [0003] Lily (Lilium spp.) is an important bulbous flower. The natural lifespan of lily pollen is short, and cross breeding often encounters problems such as parental flowering and long-distance hybridization. Breeders need to solve the above problems through pollen storage; in addition, pollen storage is also an important technology for the pres...

AI Technical Summary

Problems solved by technology

[0005] 1. At temperatures such as 5°C and -18°C, the lifespan of lily pollen is relatively short, only 30-80 days, and the length of pollen lifespan is unstable, which cannot meet the requirements of breeders for the anniversary or more of lily pollen. long-term storage requirements

[0006] 2. Storage at ultra-low temperature requires ultra-low temperature refrigerators or liquid nitrogen, and the cost of storage is high. When using it, the stored pollen must be awakened gradually at different temperatures, and the procedure is complicated and cumbersome.
