牧草阿尔冈金种籽发芽率试验

为了检验昭苏县草原站库房牧草种籽质量,我们分别于2010年和2011年,两次对库存的紫花苜蓿品种阿尔冈金(Algonguin)进行了发芽率试验。通过鉴定,了解了库存种子最新萌发情况,为科学指导工作提供参考依据。     

苜蓿蓟马抗性与生理活性相关性研究(英文)

[Objective] The experiment explored of resistance of different Medicago sativa through synthetic variations of all physiological indexes and the correlation analysis between physiological activity and damage degree after thrips damage. [Method] According to studying physiological activity (POD activity, SOD activity, PPO activity, PAL activity, MDA content and free proline content) of alfalfa in alfalfa resistance to different number of thrips, the correlation between physiological activity and resistance was investigated. [Result] It was shown that there were negative correlations among POD, SOD, PPO, PAL, MDA, free praline and the number of thrips, and there were negative correlations among POD, SOD, PPO, PAL, MDA, free praline and CAT. The content changes of POD,SOD,PPO,CAT,MDA and free proline in high resistant alfalfa were slow and PAL was quick and the activities of PPO,PAL,CAT were high, and the activities of POD、SOD were low. [Conclusion] The research provided theoretical basis and materials for identifying resistance varieties of alfalfa to thrip.
