Boron is one of the most limiting micronutrients to the good development and production of tomato, and the damage intensity varies with the cultivars, their phenological stages and the environmental conditions. The aim of this work was to evaluate the effects of boron concentrations in nutrient solution on agronomic performance and possible morpho-anatomical changes in leaves, stems, roots and fruit production of the cherry tomato cultivated in a hydroponic system. The experiment consisted of four concentrations of boron (1.0; 10.0; 25.0; and 50.0 μmol L −1 ) and plants evaluation at different phenological stages: 43, 53, 66 and 84 days after sowing. The concentration of 1 μmol L −1 boron in nutrient solution caused the greatest limitation to the growth and development of the tomato, from the vegetative stage, with aggravation of damage in the subsequent stages. The anatomical alterations in the leaf, stem and root tissues became more conspicuous with the advancement of the phenological stages, preventing fruit production. The estimated dose of 35 μmol L −1 boron results in the best growth and production of the tomato ‘Iracema.’

缺硼影响樱桃番茄叶、茎和根的解剖结构

硼是限制番茄良好发育和生产的微量营养素之一，其危害强度因品种、物候阶段和环境条件而异。这项工作的目的是评估营养液中硼浓度对农艺性能的影响，以及在水培系统中栽培的樱桃番茄的叶、茎、根和果实产量的可能形态解剖学变化。实验包括四种浓度的硼（1.0、10.0、25.0 和 50.0 μmol L -1 ）和不同物候阶段的植物评估：播种后 43、53、66 和 84 天。营养液中1 μmol L -1 硼的浓度对番茄的生长发育造成了最大的限制，从营养期开始，随着后续阶段的损害加剧。随着物候阶段的推进，叶、茎和根组织的解剖学改变变得更加明显，从而阻止了果实的生产。35 μmol L -1 硼的估计剂量导致番茄“Iracema”的最佳生长和产量。
