Abstract

The invention discloses a preservation method of Dendrobium candidum seeds.The preservation method includes: collecting Dendrobium candidum capsules which are full, mature and non-cracked; performing surface sterilization on the capsules; on a super clean bench, using a sterile operation method to cut open the top ends of the capsules, pouring seeds into a high-quality polypropylene screwed centrifugal tube sterilized by a high-pressure sterilization pot, and sealing for preservation.By using the preservation method to preserve the Dendrobium candidum seeds, the objective of long-time preservation can be achieved, and the seeds do not go bad and still have vitality.The germination rate reaches higher than 90% after sowing the seeds preserved by the method, so that the preservation method is worthy of popularization.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for preserving dendrobium officinale seeds with a centrifuge tube. Background technique [0002] The fruit of Dendrobium officinale is a capsule, which contains tens of thousands of powdery seeds. Artificial breeding of Dendrobium candidum seedlings is obtained by aseptic sowing of seeds, so it is particularly important to obtain well-preserved and mature Dendrobium candidum seeds. However, in actual production, if the collected whole capsules are directly stored in a refrigerator at 4°C, the epidermis of the capsules is easily softened and cracked, which is not conducive to the operation of aseptic sowing, resulting in a short storage time, which generally cannot exceed one month. moon. Therefore, existing Dendrobium candidum seed preservation technology still has deficiency. Contents of the invention [0003] The purpose of the present invention is to provid...
