Wheat stripe rust teliospore germination technology system

Abstract

The invention relates to a wheat stripe rust teliospore germination technology system, which comprises the following steps: conducting low-temperature treatment on a wheat stripe rust teliospore material for one week or longer time, treating wheat tissues (leaves or sheathes) containing wheat stripe rust teliospore with sterile water, spraying water, soaking and placing in the low-temperature environment for 24 hours, then moving out and placing in a 16DEG C incubator and naturally drying for 24 hours; and repeating the above drying-wetting operation for 2-4 cycles, then soaking the wheat tissues containing wheat stripe rust teliospore for 24 hours with sterile water, placing the wheat stripe rust teliospore-containing tissue on a 2-4% water agar medium, placing in the 16DEG C incubator for culturing, and thus observing the germination of the wheat stripe rust teliospore. The wheat stripe rust teliospore germination technology system discloses that the wheat stripe rust in China has a perfect stage, and provides technological guarantee for disclosing the action of sexual propagation of the wheat stripe rust in China in the toxicity variation.

Description

technical field [0001] The invention relates to a teliospore germination technology system of wheat stripe rust, which belongs to the field of agricultural technology. Background technique [0002] Wheat stripe rust is the most serious wheat disease in my country. In the history of the prevalence of stripe rust, it has caused huge yield loss to my country's wheat production. At present, it is still the most destructive disease on wheat in my country. Race variation is the direct cause of the "loss" of wheat disease resistance and the occurrence of wheat stripe rust. The pathways of race variation include mutation, somatic recombination, and sexual reproduction. Teliospore germination of wheat stripe rust is the first step in sexual reproduction to study race variation. However, due to the difficulty in germination of teliospores of wheat stripe rust, for a long time, no suitable method for teliospore germination of wheat stripe rust has been mastered. The establishment o...
