β-氨基丁酸诱导水稻稻瘟病抗性对活性氧代谢的影响(英文)
《Agricultural Science & Technology 》 2009
摘要:[Objective] This study was to understand the effects of β-Amino butyric acid(abbreviated as BABA) induced rice blast resistance on reactive oxygen metabolism. [Method] Using the cultivar Chaochan 2 that is highly susceptible to disease as experimental material, the changes of catalase(CAT), and superoxide dismutase(SOD) and MDA activities in rice treated by BABA were investigated. [Result] In rice plants treated by BABA, the activities of CAT and SOD increased, meanwhile the MDA content also rose to some extent, resulting in the disease resistance to rice blast. [Conclusion] By influencing reactive oxygen metabolism, BABA endows rice plants with resistance to rice blast. BABA is safe to environment and has highly resistance-inducing capacity, it could be generalized in production.


高粱优良恢复系吉R105的选育与利用
《种子 》 2009 北大核心 CSCD
摘要:吉R 105是采用地理远缘杂交和姊妹交的方法选育成的配合力高、恢复性强、综合性状好、抗性强、适应性广的优良恢复系。该系主要含有亨加利高粱亲缘。利用吉R 105配制出许多杂交种,其中辽杂22、吉杂121、本粱2号已通过国家高粱品种鉴定,吉杂122和吉杂123已通过吉林省高粱品种审定。


吉密豆1号矮秆性状遗传规律分析
《安徽农业科学 》 2009 北大核心
摘要:[目的]探明吉密豆1号矮秆性状的遗传规律。[方法]以吉密豆1号(矮秆,母本)、吉育47(株高正常,父本)、辽豆14(株高较高,父本)及其杂交F1、F2代和回交BC1、BC2代为材料,研究吉密豆1号矮秆基因的遗传规律。[结果]F1代平均株高均高于中亲值,矮秆性状表现为隐性;杂交组合(吉密豆1号×吉育47、吉密豆1号×辽豆14)与双亲回交世代株高的分离比例符合1对基因控制性状的分离比例;2个组合F2代株高的分离比例为3∶1。[结论]吉密豆1号的矮秆性状受1对隐性基因控制。
