摘要
分别以0、10、50、100、200、500mmol／L外源一氧化氮（nitric oxide，NO）供体硝普钠（SNP）处理豌豆、黄瓜、玉米和刺槐种子及其砂培幼苗。结果表明：10-100mmol／L SNP对种子发芽势、发芽率及幼苗的根长、叶绿素含量和生物量有明显的促进作用，随着SNP浓度的增加，种子萌发和幼苗生长明显受抑制，不同植物受抑制程度的差异明显。
The seeds and seedings planted in sand of pea, cucumber, maize and acacia were soaked by 0,10,50,100,200, 500 mmol/L sodium nitroprusside （SNP）, a nitric Oxide （NO） donor. The results showed that 10-100mmol/L-SNP could promote the germination vianility and germination percentage of seeds, the root length, chlorophyll contents and dry weights of seedings. With the concentration of SNP increased, the seed germination and seedling growth were inhibi- ted obviously. The inhebitory degree was different observably among plant species.
