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。

With the increasing of light intension, number, length and diameter of root and root-shootratio were all increased.
平均生根数、根长、根冠比和根粗均随光照强度的增强而增大。

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.
