摘要

摘要扦插繁殖是一种繁殖方法,具有早熟、均匀栽培的优点。一些因素影响繁殖和生根,如扦插大小和一年中采集的时间。因此,本工作旨在根据生产的克隆植物的生理质量,评估白肉红火龙果枝节的理想大小及其通过切割进行作物繁殖的收集时间,以实现更适当的培养管理并增加种植面积。该实验在工程学院(UNESP)进行,使用在两个季节(夏季和冬季)收集的三种长度分别为10、20和40厘米的枝节大小(插条)。所用的实验设计是完全随机的,分时间方案,不依赖于因素和20个重复。在切割后60天对与芽和枝节生根相关的生物特征因素进行评估。结果表明,不同处理之间存在显著差异,芽数之间存在显著的相互作用。可以得出的结论是,关于分支的大小,建议在可能的情况下使用40厘米长的分支;关于采集时间,建议在冬季进行采集,以利于培育出质量更好的克隆植物。

Cladode size and collection time for pitahaya propagation
ABSTRACT Cutting is a propagation method with the advantages of early production and uniform cultivation. Some factors influence propagation and rooting, such as the cutting size and the time of year the collection is performed. Thus, the present work aimed to evaluate the ideal size of white-fleshed red pitahaya cladodes and the time of their collection for crop propagation by cutting in view of the physiological quality of the produced clonal plants to enable more appropriate cultural management and increase the cultivation area. The experiment was conducted at the Faculty of Engineering (UNESP) using three cladode sizes (cuttings) with lengths of 10, 20 and 40 cm collected in two seasons (summer and winter). The experimental design used was completely randomized in a split-time scheme, with no dependence on the factors and 20 replicates. Evaluations of the biometric factors related to sprouts and cladode rooting were carried out 60 days after cutting. According to the results, there were significant differences among treatments, with a significant interaction of the number of sprouts. It can be concluded that, regarding the size of the cladodes, it is recommended, when possible, to use cladodes 40 cm in length; regarding the time of collection, it is recommended that collection be conducted in the winter period to favor the development of better-quality clonal plants.
