- 摘要:
- 以百日草（Zinnia elegans）为试材，缺钾营养液为对照（CK），研究了不同K+浓度（4、8、12、16 mmol?L-1）营养液对其苗期生长指标和根系形态参数的影响。结果表明：随着K+浓度的增加，百日草幼苗的生长指标均呈现先上升后下降的趋势，当K+浓度为12 mmol?L-1时生长量与各生长指标达到最大。各浓度K+处理的百日草幼苗株高显著高于CK，其中12 mmol?L-1 的K+处理最高，比对照增加了80.52%；与CK相比，K+处理的根长增长，根表面积和根体积增加，均以12 mmol?L-1的 K+处理最高。适宜浓度的K+（12 mmol?L-1）有利于百日草幼苗的生长，对地下部生长的促进作用大于地上部，K+浓度过高会抑制幼苗生长。
- Abstract:
- Zinnia elegans was used as experimental materials，potassium deficiency nutrient solution was used as control (CK)，effects of different concentration (4，8，12，16 mmol?L-1) of potassium sulfate on the index of seedling growth and root morphology were studied.The results showed that the index of Zinnia elegans seedling growth increased firstly and then declined with the increasing K+ concentration，the indicators reached the highest when K+ concentration was 12 mmol?L-1.The plant height of Zinnia elegans seedlings treated with K+ were significantly higher than that of control，and when K+ concentration was 12 mmol?L-1，it was the highest，with an increase of 80.52% compared with the control.K+ treatment increased the root length，root surface area and root volume，and all these indicators were the highest under 12 mmol?L-1 K+ treatment.The suitable concentration of K+(12 mmol?L-1) had promotive effect on the growth of Zinnia elegans seedlings,the promoting effect on underground growth was greater than that of overground，higher concentration of K+ had negative effects on growth of Zinnia elegans.
