Abstract

The analysis of productive architecture of plants involves macroscopic observation of spatial distributions of different vegetative and reproductive organs. However, few studies have evaluated these aspects in dragon fruit plants for production purposes. The objective of this study was to evaluate vegetative, reproductive, and quality parameters of dragon fruit plants (Hylocereus polyrhizus; variety Cebra) based on the position and size of cladodes, considering morphological, production, and quality characteristics of the fruits. The experiment was conducted from September 2016 to May 2018, using a completely randomized design in a 3×4 factorial arrangement, consisted of three positions of cladode insertion in the plant (primary, secondary, and tertiary) and four different cladode sizes (≤ 20 cm; 21-40 cm; 41-60 cm, and 61-80 cm), with five replications and six cladodes per plot, totaling 360 evaluated cladodes. According to the results, vegetative and reproductive characteristics of dragon fruit plants variety Cebra were affected by the cladode position and size. Fruits developed on primary cladodes with sizes of 21 to 40 cm presented, in general, better-quality characteristics. All evaluated physical and physicochemical characteristics were affected by the cladode position and size, except for titratable acidity and soluble solids to titratable acidity ratio. Fruits developed on cladodes smaller than 20 cm had lower quality. Therefore, maintaining and promoting the growth of primary cladodes with sizes of 21 to 40 cm and removing those smaller than 20 cm is recommended.

根据菌核大小和位置确定的根瘤菌生产性能

对植物生产结构的分析涉及对不同无性和生殖器官空间分布的宏观观察。然而，很少有研究以生产为目的对火龙果植物的这些方面进行评估。本研究的目的是根据火龙果（Hylocereus polyrhizus；品种 Cebra）节间的位置和大小，评估火龙果植株的无性、生殖和质量参数，同时考虑果实的形态、产量和质量特征。试验于 2016 年 9 月至 2018 年 5 月进行，采用 3×4 因式排列的完全随机设计，由植株上的三种插入位置（一级、二级和三级）和四种不同的节片尺寸（≤ 20 厘米；21-40 厘米；41-60 厘米和 61-80 厘米）组成，每小区 5 个重复，每个重复 6 个节片，共评估 360 个节片。结果表明，火龙果植株品种 Cebra 的无性系和生殖特性受节位和大小的影响。一般来说，在 21 至 40 厘米大小的主茎上结出的果实质量更好。除了可滴定酸度和可溶性固形物与可滴定酸度的比率外，所有评估的物理和理化特性都受茎节位置和大小的影响。在小于 20 厘米的茎节上结出的果实质量较差。因此，建议保持并促进 21 厘米至 40 厘米大小的主轴生长，并去除小于 20 厘米的主轴。
