Environmental stresses are the main constraints on agricultural productivity and food security worldwide. This issue is worsened by abrupt and severe changes in global climate. The formation of sugarcane yield and the accumulation of sucrose are significantly influenced by biotic and abiotic stresses. Understanding the biochemical, physiological, and environmental phenomena associated with these stresses is essential to increase crop production. This review explores the effect of environmental factors on sucrose content and sugarcane yield and highlights the negative effects of insufficient water supply, temperature fluctuations, insect pests, and diseases. This article also explains the mechanism of reactive oxygen species (ROS), the role of different metabolites under environmental stresses, and highlights the function of environmental stress-related resistance genes in sugarcane. This review further discusses sugarcane crop improvement approaches, with a focus on endophytic mechanism and consortium endophyte application in sugarcane plants. Endophytes are vital in plant defense; they produce bioactive molecules that act as biocontrol agents to enhance plant immune systems and modify environmental responses through interaction with plants. This review provides an overview of internal mechanisms to enhance sugarcane plant growth and environmental resistance and offers new ideas for improving sugarcane plant fitness and crop productivity.
环境胁迫是全球农业生产力和粮食安全的主要制约因素。全球气候的突然剧烈变化使这一问题更加恶化。甘蔗产量的形成和蔗糖的积累受到生物和非生物胁迫的显著影响。了解与这些胁迫相关的生化、生理和环境现象对于提高作物产量至关重要。本综述探讨了环境因素对蔗糖含量和甘蔗产量的影响,并强调了供水不足、温度波动、病虫害的负面影响。本文还解释了活性氧(ROS)的机制、环境胁迫下不同代谢物的作用,并突出了甘蔗中与环境胁迫相关的抗性基因的功能。本综述进一步讨论了甘蔗作物改良方法,重点是内生机制和联合内生菌在甘蔗植株中的应用。内生菌在植物防御中至关重要;它们产生生物活性分子,作为生物防治剂增强植物免疫系统,并通过与植物相互作用改变环境反应。本综述概述了增强甘蔗植株生长和环境抗性的内部机制,并为提高甘蔗植株适应性和作物生产力提供了新思路。
