| 摘 要： | 研究了顶芽、节数和埋藏深度对穗花狐尾藻、黑藻、篦齿眼子菜、菹草、金鱼藻和轮藻等6种沉水植物断枝再生能力的影响.结果表明,顶芽显著抑制了菹草的断枝再生能力,但是对其它5种植物没有显著影响;随着节数增加,断枝萌生再生枝和根的能力显著增强,总体上,5节以上的断枝具有明显更强的再生能力;穗花狐尾藻和6节以下的黑藻在埋藏条件下没...

| Abstract: | The effects of apical tip,node number and burial depth on regeneration abilities of vegetative fragments of six submerged plant species Myriophyllum spicatum,Hydrilla verticillata,Potamogeton pectinatus,P.crispus,Ceratophyllum demersum and Chara spp.,were conducted.The results showed no significant changes occurred in the numbers of regenerated shoots and roots on fragments decapitated compared with the fragments with apices,except apical fragments of P.crispus had significantly lower regeneration abilities... |
