ABT生根粉和温度对几种野生蔬菜插条生根的影响

在不同温度下对仙人掌、胭脂掌、闭鞘姜3种植物插条进行ABT生根粉促进生根试验.结果表明:仙人掌插条也可作为很好的无性繁殖材料,胭脂掌不宜以插条扦插繁殖.ABT3对仙人掌插条的生根具有很好的促进效果.在ABT生根粉促进下,35℃是仙人掌、闭鞘姜生根的适宜温度.

GL和ABT生根液对几种植物插条生根的作用比较

Application of rooting reagents GL and ABT promoted the formation of adventitious roots in cutting of mung beau hypocotyl. The treatment of GL significantly stimulated rooting number and range, which was more effective than that of ABT, so was the combined treatment of GL and IBA. However, compared with GL, ABT and ABT + IBA could increase root fresh weight and root length. The rooting number and range of adventitious roots in cutting of some woody plants(eg. Carmona microphylla and Glyptostrobus pensllis) were markedly increasing by the treament of GL (250 mg/L) in comparison with ABT treatment. On the contrary, ABT(250 mg/L) caused a remarkable increase in percentage of rooting for adventitious roots by comparison with GL reagent.

促根剂对VA菌根接种剂质量的影响

进行了复合细胞分裂素、ABT生根粉、发根土壤杆菌(Agrobacterium rhizogenes)发酵滤液等促根剂促进地豆(Phaseolus vulgaris L.)根量增加,从而提高 VA菌根接种剂质量的研究。结果表明:促根试验和盆栽试验中,三种促根剂在一定的浓度下均有一定的促根作用,其中以复合细胞分裂素5000倍液、生根粉 ABT_1 20ppm两处理效果较好,其基质中孢子产量和其它促根剂处理及对照比较,差异均达到显著水平。

使用海藻酸盐提取血足迹及增强显现的方法研究

目的:进一步研究使用海藻酸盐制模提取不同客体上潜血足迹及化学增强显现方法。方法:依据海藻酸盐能和不同承载客体上血足迹中血的结合原理,利用多种海藻酸盐制模材料提取不同客体表面潜在的血足迹印痕,并通过氨基黑、ABTS试剂加以显现。结果:海藻酸盐印模材料能够完整提取承痕客体上的潜在血足迹,经过显现可以观察到清晰的细节特征。结论:海藻酸盐制模材料能够提取不同客体上的潜在血足迹,并可以通过化学显现方法增强反差,为检验鉴定提供条件。
