[Abstract] Plants use gravity as a guide for growth and development. Gravitropism, a gravity-directed growth process, directs upward shoot movement for efficient photosynthesis and gaseous exchange. In addition, it also directs downward growth of roots in soil, for assimilation of water and nutrients required for growth and development. Using time lapse video imaging this process can be efficiently studied in a real time scale. The analysis of the response under different conditions can help to unravel the mechanisms regulating gravitropism.
[摘要] 植物使用重力作为生长和发展的指导。 重力向导，重力定向生长过程，引导向上的射击运动，有效的光合作用和气体交换。 此外，它还指导土壤中根的向下生长，用于同化生长和发育所需的水和营养物。 使用时间推移视频成像，可以以实时尺度有效地研究该过程。 在不同条件下的响应的分析可以帮助解开调节向地性的机制。
