摘要

在农业中使用生物刺激素为提高资源利用效率提供了一种可持续和高效的技术。生物刺激剂可以促进营养生长,增强植物对生物和非生物胁迫的耐受性。番茄(Solanum lycopersicum L.)对干旱胁迫非常敏感,特别是在坐果和果实发育阶段。在意大利,选择了具有抗旱性的长储番茄基因型。在这项为期2年的研究中,研究了不同生物刺激剂(甜菜碱、海藻提取物、植物蛋白水解物和动物蛋白水解物)在叶片上的施用,以确定在不灌溉的情况下对西西里岛栽培的当地番茄品种(Pizzutello)产量和品质的影响。甜菜碱处理植株的干物质(9.9%)和固溶物(6.9°Brix)含量最高。以结瘤草和动物蛋白水解物处理的植株钾离子浓度最高,而以植物蛋白水解物处理的植株钙离子浓度最高。经甜菜碱处理的番茄硝酸盐含量最高。用植物蛋白水解物处理的植株的可售产量最高(13.8 t ha - 1),比对照植株提高了17.4%。未售产量最高的是对照植株和用甜菜碱(1.1 t hm -1)处理的植株。总之,我们可以说每种生物刺激剂对所分析的不同参数有不同的影响。总的来说,在有限的水分条件下,生物刺激素的应用改善了番茄的生长、生产力和质量。我们的研究结果强调了生物刺激素应用的潜力,可以优化当地著名品种的产量和果实质量。这项研究表明,Pizzutello番茄的农艺性能有所提高,这不仅对满足消费者对高品质传统番茄日益增长的需求,而且对提高食品工业所重视的技术性状具有特别重要的意义。

A Two-Year Evaluation of Biostimulant Effects on Yield and Quality Parameters of Tomato Landrace ‘Pizzutello Delle Valli Ericine’ Cultivated Without Irrigation

A Two-Year Evaluation of Biostimulant Effects on Yield and Quality Parameters of Tomato Landrace ‘Pizzutello Delle Valli Ericine’ Cultivated Without Irrigation

The use of biostimulants in agriculture provides a sustainable and efficient technology to improve resource-use efficiency. Biostimulants may boost vegetative growth, enhancing plant tolerance to biotic and abiotic stress. The tomato (Solanum lycopersicum L.) is sensitive to drought stress, particularly during fruit setting and fruit development stages. In Italy, long-storage tomato genotypes characterised by drought resistance were selected. In this 2-year study, the foliar application of different biostimulants (betaine, seaweed extracts, vegetal protein hydrolysate and animal protein hydrolysate) was evaluated to determine effects on yield and quality of a local tomato landrace (Pizzutello) cultivated in Sicily without irrigation. The highest dry matter (9.9%) and solid soluble content (6.9° Brix) were observed in plants treated with betaine. Plants treated with A. nodosum or animal protein hydrolysate showed the highest potassium concentrations, whereas those supplied with vegetal protein hydrolysate had the highest calcium concentrations. Tomato treated with betaine were found to have the highest nitrate concentrations. The highest marketable yield (13.8 t ha−1) was recorded in plants treated with vegetal protein hydrolysate, with an increase of 17.4% compared to the control plants. The highest unmarketable yield was observed in control plants and in those treated with betaine (1.1 t ha-1). In conclusion, we can say that each biostimulant had a different effect on the different parameters analysed. Overall, the application of biostimulants has improved tomato growth, productivity and quality in limited water conditions. Our results highlight the potential of biostimulant applications to optimise both the yield and fruit quality of renowned local varieties. This study demonstrated the improvement in the agronomic performance of the Pizzutello tomato, which is particularly significant not only in response to the growing consumer demand for high-quality traditional tomatoes, but also for the enhancement of the technological traits valued by the food industry.
