摘要
磷在植物的生命周期全程中,特别是生长繁殖环节中不可或缺。不同的植物,利用土壤中磷素的能力存在差异,因此研究低磷胁迫下植物在生长及生理特性方面的响应情况很有必要。本文对低磷胁迫下植物生长及结构、光合特性、生理指标以及叶片主要营养元素方面的响应及表现进行综述,有利于进一步探索高等植物耐低磷胁迫能力,为林业生产提供参考。
Phosphorus is a very important element throughout the life cycle of plants,especially in the growth and reproduction process.Plants differ in the ability to utilize phosphorus in the soil.Thus,it is necessary to investigate the physiological and ecological response mechanism of plants under low phosphorus stress.In this paper,the response mechanism of higher plants under low phosphorus stress involving indicators of plant growth and structure,photosynthesis characteristics,physiogical indicators and major nutrients in leaves was summarized to know about the resistant ability to low phosphorus stress and support the forestry production.
