Increasing its root to shoot ratio is a plant strategy for restoring water homeostasis in response to the long-term imposition of mild water stress.
在长时间轻度水分胁迫条件下，植物会增加根与地上部的比例以恢复水分的平衡。
Root to shoot ratio of upland rice (0.116) was remarkably bigger than that of paddy rice (0 087). Root respiration rate of the former was 2.7 times of the latter.
覆草旱作的根冠比(0.116)显著大于常规水稻(0.087)，前者的根系呼吸强度是常规水稻的2.7倍。
The higher the precipitation, the greater the root depth, total root length and root diameter, the more lateral roots and the lower ratio of root to shoot.
降雨量越大，根系越深、总根长越大、根系直径越大、侧根越多、根冠比越低。
The ratio of root biomass to shoot biomass of rhizomatic root plants was 0.2, which was higher than that of fibril root plants(0.1).
根茎型植物的根生物量与地上生物量的比值为0.2，显著高于须根型湿地植物（0.1）。
With the improvement of rice cultivars, root dry weight and the ratio of root to shoot were increased, but the amount of root bleeding sap was reduced.
随品种的演进，抽穗期根重以及根冠比提高，但根系伤流液量减少。
Under low phosphorus condition, the ratio of root to shoot in all genotypes increased; uptaking and distribution of p, k, Ca, Mg, Fe, Zn between roots and shoots also changed.
低磷胁迫增大了植株的根冠比，改变了植株对营养元素的吸收及其在地上部和根系的分配。
