摘要
甘蔗是世界上重要的糖料和能源作物,对于我国食糖产业发展具有举足轻重的作用。但是,我国甘蔗种植面积正不断减少,呈现出向高海拔、土壤贫瘠等生产条件差的地方转移的趋势,因此遭受的逆境胁迫程度日益加深,严重影响了甘蔗的生长发育及产量形成。如何解决逆境胁迫下甘蔗的产量问题是目前生产上面临的重要课题。目前最好的解决办法还是培育高抗逆品种,为了给甘蔗抗性品种选育提供参考,本文对甘蔗的各种逆境,如低温、干旱、高盐、重金属等伤害与抗逆性的生理生化机制及甘蔗抗逆相关功能基因的挖掘研究进行了综述,以期系统地了解甘蔗逆境研究现状,并提出了甘蔗抗逆育种需要开展的关键工作,以期为甘蔗抗逆相关研究方向的设定、抗性机理和抗性品种的选育提供借鉴。
Sugarcane is a worldwide important crop for sugar and bio-energy, and play a key role in sugar industry. At present, its planting area is decreasing and presenting a trendency that the planting regions are moving to poor environments such as high altitude and barren land. As a result, the crop are suffering more and more serious stress ,which vastly impacts the growth and yield formation of sugarcane variety. Improving sugarcane yield in various stress environments has become an important challenge for sugarcane industry. Corp breeding history demonstrated that the best way to solve these questions mentioned above was breeding and extending these varieties with high resistance to stress. In order to provide some directions for sugarcane resistant breeding, the bio-chemical and physiological mechanism involved in harm and resistance to various abiotic stress, such as low temperature, drought, salt, heavy met- al,were summarized, and the research progress of resistant gene to abiotic stress was also reviewed in this paper. The aim of this work was to offer a systemic and precise description for the studies on resistance to abiotic stress of sugar- cane and proposed some thoughts and strategies on resistant variety breeding of sugarcane. These knowledge can proved some references for making research direction ,resistance mechanism research and resistant variety breeding.
