Heavy metals had different effects on seed germination and radicle growth.
结果表明:(1)重金属对油菜种子萌发的抑制作用依次为Hg2+>Cd2+和Co2+>Ni2+>Zn2+,而对胚根生长的毒害作用依次为Hg2+>Cd2+>Co2+>Ni2+>Zn2+。
Effects of water deficit and iron deficit on photosynthetic characteristics and root growth of maize;
缺水和缺铁胁迫对玉米光合作用特性和根生长的影响
Root growth test indicated that when the concentration of copper was 0.
根生长实验表明 ,0 。
Chlorsulfuron adversely affected root growth in most crops.
０μｇ／ｋｇ时，杂交大豆品种（系）“黑２”和“宁镇３号”的根生长受到显著抑制，而常规系统选育品种“泰兴黑豆”则在５μｇ／ｋｇ时才受到显著抑制。
It was found that root biomass of plants flooded for 60d was significantly lower than that of controlled plants.
结果表明:水淹60-d后,秋华柳根生物量显著低于未淹对照组植株;水淹20-d时,全淹和半淹组植株可溶糖、淀粉和总糖含量与对照组差异不显著。
When the nutrient levels in the original patches were low, coarse root biomass ratio (coarse root biomass in the D/total coarse root biomass), coarse root length ratio (coar.
就低养分起始斑块而言 ,粗根生物量、粗根长度、粗根表面积和细根长度在高养分目标斑块中的分配比例均小于其在低养分目标斑块中的分配比例 ,而细根长度及其密度、细根表面积指数及其密度的变化恰好相反。
