对柔软滨麦草及其与感病亲本普通小麦 7182的异染色体后代抗小麦条锈菌的组织病理学研究结果显示 ,柔软滨麦草叶面没有锈菌侵染点形成 ,且抗病表型为免疫型 ,因此其抗锈性完全表现为锈菌侵入前的非寄主抗病性。而其后代具有锈菌侵入前、侵入中、侵入后不同阶段的寄主抗锈性 ,侵入前的抗锈性表现为气孔的运动和气孔下的荧光物对芽管正确定向和附着胞分化的影响 ,侵入中和侵入后的抗锈性表现为伴随寄主细胞坏死的侵入中断和菌落败育 Histopathological studies on the stripe rust resistance of heterochromic offspring of Fusarium graminearum and its susceptible parent 7182 showed that there was no rust infection point on the Fusarium graminearum and the resistance phenotype was immune Therefore, the rust resistance is completely manifested as non-host resistance before rust intrusion. While the descendants had anti-rust properties of host before, during and after invasion, and the anti-rust performance before invasion was the movement of stomata and the influence of the stomata under the stomata on the proper orientation and attachment of shoot buds , Resistance to rust after invasion and invasion is manifested as interruption of invasion accompanied by necrosis of host cells and abortion of colonies
