摘要

芒果是巴西出口最多的水果,特别是生长在旧金山谷(热带半干旱地区),那里温度高,空气湿度低,这种条件会给植物造成压力。因此,本研究旨在评估不同防晒剂对生长在半干旱环境中的“Palmer”芒果树的非生物胁迫的缓解效果。试验设计包括6个处理,4个重复,每个地块3株植物的随机分组。各组采用不同的防晒霜治疗策略:(T1)对照(不涂防晒霜);(T2)碳酸钙(50 g·L−1);(T3)防晒霜(5 mL·L−1);(T4)防晒霜(5ml·L−1)+碳酸钙(50g·L−1);(T5)防晒霜(5ml·L−1)+防晒硅浓(20ml·L−1)和(T6)防晒霜(20ml·L−1)。结果表明,考虑到评估的时间间隔,防晒霜对芒果的非生物胁迫有明显的减弱作用,并且随着时间的推移具有持续的效果。防晒霜明显促进分化的叶片覆盖模式,保护光合机构,提高其性能,从而提高植物储备的产量。单独使用碳酸钙可以促进很短的保护效果,在使用几天后没有积极的反应。防晒霜对芒果果实产量有影响,与对照处理相比,防晒霜处理(20 mL·L−1)增加了4.2 t·ha−1。

Does the sunblock alleviate abiotic stress in mango trees grown in the tropical semiarid?
Abstract Mango is the most exported fruit of Brazil, especially grown in São Francisco Valley (tropical semiarid) where there is high temperatures and low air humidity, a condition that can cause stress to plants. Thus, the current study aimed to evaluate the effectiveness of different sunblocks to alleviate the abiotic stress of “Palmer” mango trees grown in a semiarid environment. The experimental design consisted of randomised blocks with six treatments, four repetitions and three plants per plot. The treatments consisted of different strategies of sunblocks as follows: (T1) control (no sunblock); (T2) calcium carbonate (50 g · L−1); (T3) sunblock (5 mL · L−1); (T4) sunblock (5 mL · L−1) + calcium carbonate (50 g · L−1); (T5) sunblock (5 mL · L−1) + sunblock silicon concentrated (20 mL · L−1) and (T6) sunblock (20 mL · L−1). The results indicate a clear action of sunblock in attenuating the abiotic stress of mango, with a persistent effect with time elapsing, considering the evaluated interval. The sunblock clearly promotes a differentiated leaf coverage pattern, protecting the photosynthetic apparatus and increasing its performance and consequently improving the production of plant reserves. The use of calcium carbonate individually promotes a very short protective effect, without positive reflexes after a few days of application. Mango fruit yield is affected by the sunblock with an increase of 4.2 t · ha−1 from the treatment with sunblock (20 mL · L−1) in relation to the control treatment.

期刊介绍: Folia Horticulturae is an international, scientific journal published in English. It covers a broad research spectrum of aspects related to horticultural science that are of interest to a wide scientific community and have an impact on progress in both basic and applied research carried out with the use of horticultural crops and their products. The journal’s aim is to disseminate recent findings and serve as a forum for presenting views as well as for discussing important problems and prospects of modern horticulture, particularly in relation to sustainable production of high yield and quality of horticultural products, including their impact on human health.
