摘要

盐渍化是影响世界农业生产的重要环境风险之一。在这种条件下,采用传统的栽培方法,糖生植物(如番茄)会受到多种胁迫,如离子毒性、渗透胁迫、营养干扰、氧化损伤和代谢紊乱,从而导致生长受抑制和产量下降。在这种情况下,我们研究的主要目的是比较番茄植物(Solanum lycopersicum L.)与盐生物种 Arthrocaulon macrostachyum 在盐分影响土壤中单作(TM)或间作(TH)种植的生理、激素、代谢和农艺反应。结果表明,与 TM 相比,间作系统(TH)降低了土壤电导率、Na+ 和 Cl- 含量,改善了番茄植株的矿物质营养。此外,TH 降低了番茄植株的渗透胁迫,改善了水势,提高了水分利用效率,同时保持了气体交换参数的完整性;因此,番茄产量得以提高。此外,在 TH 条件下,胁迫激素(ABA、SA 和 JA)与生长调节激素(GA、辅酶和细胞分裂素)的比例下降。代谢组学分析表明了不同积累代谢物的明确模式。在 TH 条件下丰度较高的一些代谢物与苯丙类生物合成和苯丙氨酸代谢有关,而丙氨酸、天门冬氨酸和谷氨酸代谢、单萜生物合成和丁酸代谢途径则出现下调。我们的研究结果证明了大戟科植物在盐渍土壤脱盐和提高混合栽培番茄产量方面的重要性。事实上,这种间作系统为农民提供了一种低成本的生物解决方案,在提高产量的同时也保护了环境。

Intercropping salt-sensitive Solanum lycopersicum L. and salt-tolerant Arthrocaulon macrostachyum in salt-affected agricultural soil under open field conditions: Physiological, hormonal, metabolic and agronomic responses
Salinity is one of the important environmental risks affecting agricultural production in the world. Under this condition and with the conventional cultivation methods, glycophyte plants, like tomato, are subjected to many stresses, such as ion toxicity, osmotic stress, nutritional disturbance, oxidative damage and metabolic disorders, which cause growth inhibition and yield reduction. In this context, the main objective of our study was to compare the physiological, hormonal, metabolic and agronomic responses of tomato plants (Solanum lycopersicum L.) grown in monoculture (TM) or intercropping (TH) with the halophytic species Arthrocaulon macrostachyum in a salt affected soil. The results showed that the intercropping system (TH) reduced the soil electrical conductivity, and Na+ and Cl- contents, improving mineral nutrition in tomato plants compared to TM. In addition, TH decreased the osmotic stress, improved water potential and increased water use efficiency in tomato plants, whereas the integrity of gas exchange parameters were maintained; as a consequence, an increase in tomato yield was achieved. Moreover, the ratio of stress hormones (ABA, SA and JA) to growth regulating hormones (GA, auxins and cytokinins) decreased under TH. Metabolomic analysis showed clear defined patterns of differentially accumulated metabolites. Some of the metabolites with higher abundance in TH were linked to phenylpropanoid biosynthesis and phenylalanine metabolism, whereas alanine, aspartate and glutamate metabolism, monoterpenoid biosynthesis and butanoate metabolism pathways were downregulated. Our results support the importance of A. macrostachyum in the desalination of salt-affected soils and in the improvement of tomato yield in mixed culture. Indeed, this intercropping system offers farmers a low-cost biosolution that improves yields while respecting the environment.

期刊介绍: Environmental and Experimental Botany (EEB) publishes research papers on the physical, chemical, biological, molecular mechanisms and processes involved in the responses of plants to their environment. In addition to research papers, the journal includes review articles. Submission is in agreement with the Editors-in-Chief. The Journal also publishes special issues which are built by invited guest editors and are related to the main themes of EEB. The areas covered by the Journal include: (1) Responses of plants to heavy metals and pollutants (2) Plant/water interactions (salinity, drought, flooding) (3) Responses of plants to radiations ranging from UV-B to infrared (4) Plant/atmosphere relations (ozone, CO2 , temperature) (5) Global change impacts on plant ecophysiology (6) Biotic interactions involving environmental factors.
