- 摘要:
- 以百日草(Zinnia elegans Jacq.）、波斯菊(Cosmos bipinnata Cav.）、黑心菊（Rudbeckia hirta L.）、花环菊(Chrysanthemum carinatum)和小丽花(Dahlia pinnate cv.）5种菊科花卉种子为试材，研究氯化钠型和氯化钙型两种类型融雪剂对种苗生长发育的影响。结果表明：同种花卉对不同类型融雪剂的耐受性不同，同型融雪剂对不同种花卉的影响也不同；高浓度的融雪剂可抑制种苗生长发育，而低浓度的则有促进作用；氯化钙型融雪剂较氯化钠型融雪剂对种苗的毒害作用小；百日草对两型融雪剂的耐受性均较强，花环菊也有一定的耐受性，而波斯菊的耐受性较弱。
- Abstract:
- The effect of sodium chloride and calcium chloride deicing salts on germination and growth of the Asteraceae seeds of Zinnia elegans, Cosmos bipinnata, Rudbeckia hirta, Chrysanthemum carinatum and Dahlia pinnate were studied.The results showed that the effect of different deicing salts on same seed was different and the effect of same deicing salts on different seeds was different.Hight concentrations of deicing salts inhibited the seedling growth,but low concentrations could promoted it.Toxic effects of calcium chloride deicing salts were smaller than sodium chloride deicing salts on seedling.Zinnia elegans showed strong tolerance on two types of deicing salts.Chrysanthemum carinatum have a little tolerance.Cosmos bipinnata showed weak tolerance.
