诱变处理

The mutagenic effect of 3mM 5mM was better than that of others.

和苯甲酸胺复合处理的诱变效应较好。

Soaking seed of rice and wheat with zymolytic liquid of Trichoderma harziaiarum, Trichoderma DWC and Trichoderma viride, comparing with germinate ratio, germinate force, root length, bud length and ratio of root to bud, the results show that 50 times dilute zymolytic liquid of Trichoderma harziaiarum has a relatively notable promote role for germinate of seed .The effect of Trichoderma viride to germinate of seed is not evidence. Trichoderma DWC for seed sprout has certain inhibition.

据此，采用哈茨木霉作为出发菌株，通过离子束诱变，从大菌落株中筛选出促进生长的高产突变株——h-13菌株，通过对用该菌株发酵液处理后的水稻及小麦的种子的各项生理生化指标的测定，发现该菌株比其它菌株更能促进水稻和小麦的活力和发芽率，三天时小麦的总根长为3.03cm，比对照的1.42cm的两倍还多，并且能够明显提高种子发芽后的淀粉酶和蛋白酶的活力，其活力都是对照的两倍左右。

The same mutagen in the same concentration could increase the ratio of mutagen to PLB with the extended time.

同浓度的同种诱变剂随处理时间的增加材料的变异程度有增大趋势，但不很显著。

结论本研究为返回式卫星搭载处理的空间诱变育种提供了一个新的佐证，表明它是农作物育种的一条有效新途径。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
