Abstract

Environmental concerns are gradually reducing the global yield capacity of agricultural systems, with climate change representing the most significant challenge. Globally, Potatoes are the most essential non-cereal crop. Therefore, understanding the potential impacts of climate change on potato production is crucial for maintaining future global food security. This study aims to explore the roles played by PGPMs in two distinct regions, which are characterized by different climatic conditions, to assess their influence on two potato varieties, namely Siena and Bellini. Inoculation with these strains, particularly the Aureobasidium pullulans strains Ach1-1 and Ach1-2, resulted in significant improvements in growth and yield. In 2018, impressive yields of 194.1 kg/0.05 ha and 186.6 kg/0.05 ha were recorded for the two strains, with the Ain Taoujdate site achieving yields of 157.1 kg/0.05 ha and 151.1 kg/0.05 ha for each of the two strains. Additionally, further observations revealed that the Siena variety is more susceptible to rot than the Bellini variety. However, Ach1-1 and Ach1-2 strains had a significant effect on this rot, showcasing their potential to mitigate this negative issue in the Bellini variety. These promising results underscore the potential of PGPMs to enhance potato production in the Fez–Meknes region of Morocco, contributing to global food security amid climate change.

摩洛哥不同气候条件下促进植物生长的微生物对马铃薯种植的影响评估

环境问题正在逐渐削弱全球农业系统的产量能力，而气候变化则是最大的挑战。在全球范围内，马铃薯是最重要的非谷类作物。因此，了解气候变化对马铃薯生产的潜在影响对于维护未来全球粮食安全至关重要。本研究旨在探索 PGPM 在两个气候条件不同的地区所发挥的作用，以评估它们对两个马铃薯品种（锡耶纳和贝利尼）的影响。接种这些菌株，特别是Aureobasidium pullulans菌株Ach1-1和Ach1-2，可显著提高生长和产量。2018 年，这两种菌株的产量分别达到 194.1 千克/0.05 公顷和 186.6 千克/0.05 公顷，令人印象深刻，其中 Ain Taoujdate 基地的产量分别达到 157.1 千克/0.05 公顷和 151.1 千克/0.05 公顷。此外，进一步观察发现，锡耶纳品种比贝利尼品种更易感染腐烂病。然而，Ach1-1 和 Ach1-2 菌株对这种腐烂有显著影响，显示了它们减轻贝利尼品种这一负面问题的潜力。这些充满希望的结果突出表明，PGPMs 有潜力提高摩洛哥非斯-梅克内斯地区的马铃薯产量，从而在气候变化中为全球粮食安全做出贡献。

期刊介绍： Microbiology Research is an international, online-only, open access peer-reviewed journal which publishes original research, review articles, editorials, perspectives, case reports and brief reports to benefit researchers, microbiologists, physicians, veterinarians. Microbiology Research publishes ‘Clinic’ and ‘Research’ papers divided into two different skill and proficiency levels: ‘Junior’ and ‘Professional’. The aim of this four quadrant grid is to encourage younger researchers, physicians and veterinarians to submit their results even if their studies encompass just a limited set of observations or rely on basic statistical approach, yet upholding the customary sound approach of every scientific article.
