试验以公农1号紫花苜蓿种子为实验材料,采取不同的消毒处理,选取子叶、叶片、胚轴为外植体,研究了不同消毒方式、不同外植体对公农l号紫花苜蓿品种再生的影响。结果表明:种子在消毒前,经无菌水浸泡24h(预处理)比不浸泡的消毒效果好,但是浸泡后,用酒精消毒时间不可过长;2%次氯酸钠、10%次氯酸钙、0.1%升汞三种消毒剂中,0.1%升汞消毒效果最好,种子带菌率为0%,75%的乙醇预处理后可大幅降低种子的带茵率;三种消毒剂中10%次氯酸钙一无水处理的紫花苜蓿种子发芽率最高;三种外植体均容易形成愈伤组织,经过综合比较,选取胚轴为公农1号紫花苜蓿品种的最佳外植体。
試驗以公農1號紫花苜蓿種子為實驗材料,採取不同的消毒處理,選取子葉、葉片、胚軸為外植體,研究瞭不同消毒方式、不同外植體對公農l號紫花苜蓿品種再生的影響。結果錶明:種子在消毒前,經無菌水浸泡24h(預處理)比不浸泡的消毒效果好,但是浸泡後,用酒精消毒時間不可過長;2%次氯痠鈉、10%次氯痠鈣、0.1%升汞三種消毒劑中,0.1%升汞消毒效果最好,種子帶菌率為0%,75%的乙醇預處理後可大幅降低種子的帶茵率;三種消毒劑中10%次氯痠鈣一無水處理的紫花苜蓿種子髮芽率最高;三種外植體均容易形成愈傷組織,經過綜閤比較,選取胚軸為公農1號紫花苜蓿品種的最佳外植體。

Medicago sativa L.CV. "Gongnong No.l" was used as experiment material, and the influence of regenerate by different disinfection methods, different explants (select the cotyledons, leaves, hypocotyls as explants) . The results showed that sterilization of seeds soaked in aseptic wat.er for 24 hours was better than that without soaking. However, after soaking with alcohol disinfectant is not long. Under constant temperature, the sterilization effects of three germicides (2% sodium hypochlorite, 10% calcium hypochlorite and l%v HgCI2) on alfalfa seeds were studied. The results showed that 1%~ HgCI2 had the greatest sterilization effect. The germ-bearing rate of seeds treated with 1%~ HgC12 was 0%. Sterilization of seeds soaked in 75% ethanol before seed sterilization decreased germ-bearing rate. The highest germination rate was observed in treatment with 1%~ HgCI2. The results showed that hypocotyl was to induce callus, was the most effective explants in the three explants.
