Abstract

Abstract The objective of this work was to determine the effect of planting densities on the yield and quality of 'Hass' avocado (Persea americana) in the department of Antioquia, Colombia. The experimental design was randomized complete blocks with three replicates. The treatments were six plant densities (204, 278, 333, 400, 625, and 816 trees per hectare) with five harvest seasons, and each experimental unit consisted of six nine-year-old trees. The highest fruit yield is obtained at 333 and 400 trees per hectare. The main harvest represents 70% (18 Mg ha-1) of the annual production, whereas the secondary (mitaca) harvest represents 30% (5.25 Mg ha-1). Yield per tree and number of avocado fruits per tree are negatively affected by the increase in planting densities. In addition, fruit quality parameters show better results at intermediate planting densities of 333 and 400 trees per hectare, with the highest ratios of mesocarp and the lowest of seed, both in fresh and dry weight.

哥伦比亚不同种植密度下鳄梨的产量和果实品质

摘要本研究的目的是确定种植密度对哥伦比亚安蒂奥基亚省“哈斯”鳄梨(Persea americana)产量和品质的影响。试验设计为完全随机区组，设3个重复。处理为6个密度(204、278、333、400、625和816棵/公顷)，5个收获季节，每个试验单元由6棵9年生树组成。最高的果实产量为每公顷333棵和400棵。主要收获占年产量的70% (18 Mg ha-1)，而次要(mitaca)收获占30% (5.25 Mg ha-1)。种植密度的增加会对单株产量和单株果数产生负面影响。此外，果实品质参数在333和400株/公顷的中等种植密度下表现较好，果皮的鲜重和干重比例最高，种子的干重比例最低。
