摘要

摘要本研究的目的是为了确定最适合的基质和扦插方式,以获得脆弱的Baccharis Baker扦插苗。从温室栽培的砧木上收集根茎扦插。收集后的岩屑在以下基质中生长:商业泥炭基基质(CPS);蛭石(VM);碳化稻壳;椰子纤维(CF);VM和CRH (1:1) (VM + CRH);VM与CF 1:1 (VM + CF);CRH与CF (1:1) (CRH + CF)混合物。试验采用完全随机因子设计,60 d后测定成活率和生根率(% SR)、地上部长(APL)和根长(RSL)、芽数(SN)和新叶数(LN)、根体积(RSV)、地上部干质量(APDM)和根干质量(RSDM)。在APL、RSL、LN、RSV和RSM的基质类型和切割之间发现了相互作用。而%SR、SN和APDM仅因切削类型不同而不同。顶端扦插具有较高的APL,节间扦插具有较高的SN、LN、RSV和APDM。CPS在这两种类型的扦插中都提高了较高的RSL,是脆弱杆菌繁殖的合适选择,特别是在节间扦插中。

Baccharis vulneraria (Asteraceae) cuttings in different substrates
Abstract The objective of the study was to identify the most suitable substrate and type of cutting to obtain seedlings from Baccharis vulneraria Baker cuttings. Apical and stem cuttings were collected from stock plants grown in a greenhouse. After collection, the cuttings were grown in the following substrates: commercial peat-based substrate (CPS); Vermiculite (VM); carbonized rice husk (CRH); Coconut fiber (CF); VM and CRH (1:1) (VM + CRH); VM and CF (1:1) (VM + CF); and CRH and CF (1:1) (CRH + CF) mixtures. The experiment used a completely randomized factorial design and, after 60 days, the percentage of survival and rooting (% SR), aerial part length (APL) and roots length (RSL), number of shoots (SN) and new leaves (LN), root volume (RSV), aerial part dry mass (APDM), and roots dry mass (RSDM) were evaluated. An interaction was found between the type of substrate and cutting for APL, RSL, LN, RSV, and RSM. On the other hand, %SR, SN and APDM differed only by cutting type. Apical cuttings showed higher APL, while internode cuttings showed higher SN, LN, RSV, and APDM. CPS promoted higher RSL in both types of cuttings, being a suitable option for the propagation of Baccharis vulneraria, particularly in internode cuttings.
