摘　　要：用海藻天然活性物质Alga600的3000倍稀释液浸种后将小麦种子加入不同浓度PEG-6000溶液,进行不同的渗透胁迫以及盆栽试验,以鉴定海藻活性物质对小麦幼苗抗旱性的影响。结果表明:Alga600浸种可以增强小麦幼苗抗渗透胁迫的能力;盆栽试验不同干旱条件下施用Alga600均能减轻干旱胁迫对质膜的伤害,减缓小麦叶片含水量的降低,降低MDA、可溶性蛋白的含量,减少抗逆调节物质脯氨酸、可溶性糖的含量,减缓小麦叶片叶绿素A的降解,可缓解干旱胁迫对小麦生长的影响。The experiment soaks seeds after the clear water and the Alga600 of 3000 time of diluent joins the wheat seed the different density PEG-6000 solution, under the different seepage forces the condition, the appraisal active material of marine the influence which grows to the wheat seedling. The result indicates： Alga600 soaks seeds may strengthen the ability which the wheat seedling anti-seepage forces; under the different arid condition employs Alga600 all can reduce arid forces to the protoplasmic membrane injury, reduces the protoplasmic membrane penetrability; increases the wheat leaf blade the water content; reduces MDA, the soluble protein content; increases the resistance adjustment matter pralines, the soluble sugar content; increases chlorophyll A the content.
