| 摘 要： | 在室温盆栽的条件下,采用不同浓度的有机胺(PTMAC)处理,研究其对黄瓜种子萌发及幼苗生长的影响。结果表明:PTMAC在10mg/L下各项指标较好,发芽势、发芽率、发芽指数、活力指数分别有不同程度的增加,尤其是发芽活力指数显著增加了43.74%;鲜重增加了34.71%,根系活力增强了138.71%;叶绿素含量在其浓度为20mg/L时最高,增加了41.47%。当PTMAC浓度超过了50mg/L时,对黄瓜种子的萌发和幼苗的生长有明显的抑制作用。

| Abstract: | The effects of organic amine(PTMAC) were studied on cucumber seed germination and seedling growth by using different concentration in this paper.The results showed that when the PTMAC concentration under 10 mg/L,each index was better,the germination potential(GP),germination rate(GR),germination index(GI),vitality index(VI) were increased apparently,especially the VI significant increased by 43.74%;Appropriate concentration of PTMAC to seedling growth had stimulative effect,when the concentration of PTMAC at 10 mg/L,fresh weight had increased obviously by 34.71%,root activity increased 138.71%,when the concentration of PTMAC at 20 mg/L,the highest content of chlorophyll increased by 41.47%.When the concentration of PTMAC more than 50 mg/L,the germination of seeds of cucumber and seedling growth had apparent inhibition. |
