| 摘 要： | 目的]探讨不同质量浓度CuSO4水溶液对银荆生长发育的影响。方法]以产自澳大利亚的银荆为试验材料,CuSO4水溶液试验设8个处理(0、0.05、0.10、1.50、2.00、4.00、5.00、6.00 mg/L),对种子进行浸泡,并对不同处理的银荆幼苗的主要生长指标进行测定。结果]不同处理间的银荆幼苗的全重、主根重、侧根重、根系数、地径粗度、苗高、复叶数之间呈极显著差异,以2.00 mg/L质量浓度的CuSO4水溶液浸种的效果最好,幼苗全重、主根重、侧根重、根系数、地径粗度、苗高、复叶数分别为0.919 g、0.325 g、0.126 g、7.28条、2.53mm、39.61 cm、6.23片,分别比对照提高136.25%、95.78%、142.31%、44.44%、59.12%、65.87%、208.42%。结论]铜能促进银荆幼苗生长,2.00 mg/L是银荆幼苗生长所需铜元素的最适浓度;铜对银荆生长存在剂量效应。 |
