| 摘 要： | 酸性土壤占世界可耕作土壤的30%~40%,且呈逐年上升趋势,铝毒是酸性土壤中作物生产的主要限制因素。作为铝富集植物,茶树体内铝含量是其他植物的几十倍,且不表现出根尖生长受抑制及根冠表皮脱落等典型铝毒症状,适宜浓度的铝还能促进茶树的生长。本文主要对茶树铝富集特性、铝在茶树细胞内存在形态及亚细胞分布、茶树对铝的生理响应、茶树耐铝聚铝的可能机理等研究进展进行了综述,并对后续研究思路作了展望。

| Abstract: | Acidification is identified in 30%-40% arable land worldwide. Furthermore, the soil acidity is gradually serious. Aluminum (Al) toxicity is a major limiting factor for plant growth and crop production in acid soils. The tea plant (Camellia sinensis (L.) O. Kuntze) exhibits good performance when exposed to a proper Al level, and accumulates high Al in the leaves without representative toxicity symptoms, such as growth inhibition of root tip, falling of the epidermis of root cap. Thus, tea plant is considered as an Al hyper accumulator. This review summarized the progress of Al accumulation, forms, subcellular location or distribution and its physiological responses of tea plant to Al. Additionally, the potential mechanisms and future researches related to Al tolerance or accumulation in tea plant were also discussed. |
