The effects of stripe rust on cyanide - resistant respiration were very larger than that of water stress 复合胁迫下,抗病小麦显然具备更强的水分调控能力,而感病品种不能有效控制病叶水分散失。
The mts in protoplast of cv . 5389 also depolymerized when treated with iwf for 60 and 120 minutes , but the depolymerization was much less than that of cv . lovrin 10 而感病品种5389原生质体在激发子处理60 、 120min时,微管骨架虽也发生解聚,但其解聚程度较洛夫林10原生质体明显轻微。
At the same time , using the genomic dna of blast sensitive cultivar c039 as a template , two fragments were obtained that were the same large dna sequence as resistance cultivar c101a51 . one sequence has conserved motifs of nbs - lrr type resistance genes , the other sequence can " t read through 同时本研究还以感病品种c039的基因组为模板,也扩增得到与c101a51抗病品种中抗病基因同源序列同样大小的dna片段,但一个有抗病基因的保守结构,另一个片段不能通读。
It is ascertained that it will increase the quantity of powdery mildew of wheat seedlings in the autumn under conditions of early sowing , over - density , over - watering , over - doses of fertilizer and growing of highly susceptible cultivars through large scale investigations in wheat fields 为了解栽培措施对防治小麦白粉病的作用,通过不同栽培措施对病情产生不同影响的大量田间调查,明确了小麦早播、密播,过量水、肥条件下的旺苗和种植高度感病品种,都会加重小麦秋苗带菌量。
