水杨酸浸种对蓖麻种子萌发的影响

Effects of Presoaking with Salicylic Acid on Germination of Seed and Some Physionlogical Characteristics of Primary Seeding of Castor

研究了不同浓度水杨酸浸种对蓖麻种子萌发及生理特性的影响 ,结果表明 :低浓度水杨酸浸种可促进蓖麻种子萌发 ,提高幼苗含水量 ,降低膜相对透性 ,且浓度愈低 ,效果越显著 ,以 0 .0 1mmol·L-1效果最佳 ;而高浓度的水杨酸则抑制蓖麻种子萌发 .

Low Concentrations of salicylic acid could promote seed germination,increased the content of water and decreased relative memberane permeability.The lower SA concentration was,the more significant effect.The effect of 0.01 mmol·L -1 SA was most significant.Concentration of salicylic acid inhibited seed germination.
