Method for quarantining imported sugarcane seeds

Abstract

The invention provides a method for quarantining imported sugarcane seeds. The method comprises the following steps: firstly, carrying out visual inspection on the seeds; if insects are found, carrying out stifling on the seeds or destroying the seeds; after the visual inspection, carrying out sterilization and insect-killing treatment on the sugarcane seeds; sowing the treated seeds into a sterilized seedling growing base material; placing the base material into a special sugarcane quarantine greenhouse to carry out isolated observation for more than three months; after the three months, collecting leaves to carry out PCR ((Polymerase Chain Reaction) detection on sugarcane Fiji diseases, mosaic diseases and bacterial blights; destroying detected positive materials immediately; transplanting detected negative materials into disinfected pot cultivation soil to carry out epidemic surveillance within a whole growth period; during the surveillance process, observing quarantine plant diseases and insect pests of a sugarcane every one month; after the quarantine is finished, harvesting sugarcane stems which do not have the quarantine plant diseases and insect pests and can be used for reproduction tests and researches. With the adoption of the method, the imported sugarcane seeds are subjected to the quarantine treatment so as to effectively prevent the dangerous plant diseases and insect pests from spreading to China along with the imported seeds to cause dangers.

Description

technical field [0001] The invention belongs to the technical field of plant protection, and specifically relates to a quarantine method for imported sugarcane seeds, which is specially used for quarantine of imported sugarcane seeds. Background technique [0002] The introduction of sugarcane is an effective way to quickly and conveniently utilize the latest breeding achievements from all over the world to improve the structure of sugarcane varieties and increase genetic resources. potential risks. How to prevent dangerous pests and diseases from being introduced into our country's sugarcane areas through introduction requires sound and strict introduction quarantine precautions to ensure that the introduced materials are free from dangerous pests and diseases. [0003] In addition, with the continuous deepening of the international sugarcane germplasm exchange work, the exchange of materials has not only been limited to sugarcane stems but also extended to the exchange of...

Problems solved by technology

[0003] In addition, with the continuous deepening of the international sugarcane germplasm exchange work, the exchange of materials has not only been limited to sugarcane stems but also extended to the exchange of sugarcane seeds. In addition, many important sugarcane diseases and insect pests are transmitted through seeds, such as the fungus. Ear disease, ear rot, systemic viral disease mosaic disease, phytoplasma disease white leaf disease, and sugarcane mites are all easily transmitted through seeds, resulting in an increasing risk of pest transmission caused by introduction

At present, there is no quarantine method for imported sugarcane seeds in China. Therefore, researching and establishing a quarantine method for imported sugarcane seeds has become the key to effectively preventing dangerous pests and diseases from spreading through the introduction of sugarcane seeds into my country's sugarcane areas.
