- 摘要:
- 以锦屏藤为试材，采用土壤和水中扦插的方法，研究了正插和倒插对插条重量及幼苗生长动态特征的影响。结果表明：以土壤为基质时，正插繁殖的幼苗生长较快，较早进入萌芽和抽枝阶段，藤条长度和叶片数均高于倒插（P<0.01）；而成活率无明显差异。水插时，正插和倒插的插条在重量变化上相似（R=0.995，P<0.01），能够较好地吸收水分。锦屏藤正插和倒插在水插生根动态上表现出明显差异，正插在多数情况下根长和生根数指标优于倒插，且在部分阶段藤条长度更长（P<0.01）；但最终在萌芽和生根的植株比例上并未表现出明显差异，形态学上端的芽在2种扦插方式中都容易萌发。生根部位上，正插插条在节、截面和皮孔处均能生根，倒插插条生根主要在节上，而在插条上端产生气生根。锦屏藤具有很强的倒插成活能力，但正插的幼苗生根能力更强且藤条长势更好；节在倒插成活中起着关键作用。
- Abstract:
- Taking Cissus sicyoide as material，the cuttage experiments were conducted in soil and water substrate respectively，the effect of normal and reverse cottage on the dynamic characteristics of cutting weight and seedling growth were studied.The results showed that in soil medium，the seedlings from normal cuttage grew faster than the seedlings of reverse cuttage.The former was earlier in sprout and branch development period，and had longer cane and more leaves(P<0.01).Survival rate had no significant difference.In water medium，similar pattern of cutting weight was observed in two cuttage treatments(R=0.995，P<0.01)，cutting could effectively uptake water from medium.The significant difference of rooting dynamic was found in normal and reverse cuttage of Cissus sicyoide .Seedlings of reverse cuttage performed well in the index of root length and rooting number in most time，and had longer cane in certain stage(P<0.01).There were no difference of percentage of survival cuttings in two groups.In addition，the buds in morphological upside of cutting were always active.The place of rooting was burl，section and lenticel in normal cutting.But roots main occurred in burl，and aerial root appeared in upper cutting in reverse cutting group.The survival capacity was high in Cissus sicyoide .Rooting capacity and cane growth were better in seedling of normal cuttage.The burl played an important role in survival of reverse cuttage.
