为探讨温度胁迫环境对薰衣草的生理特征的影响,以盆栽薰衣草CAS08#为试验材料,利用智能温室对薰衣草CAS08#进行了不同温度(30、38、42℃)下淹水处理和正常管理两种处理,研究了高温胁迫及淹水高温协同胁迫对薰衣草CAS08#的形态、MDA含量、SOD和POD活性、相对电导率的影响。试验结果表明:15 d内薰衣草对高温有一定的自我适应调节能力,在30、38、42℃高温胁迫条件下,薰衣草可以越夏;在夏季30℃高温以及淹水协同胁迫条件下薰衣草生长受阻,38℃以上高温与淹水协同胁迫条件下,薰衣草生长受阻,并在几天之内死亡,推测土壤在淹水条件下,产生了有毒有害物质使得薰衣草根部受损,薰衣草吸收水分与营养受阻而死亡。
In order to investigate the effect of temperature-induced stress on the physiological characteristics of lavender, Lavender CAS08 # was used as the experimental material and the lavender CAS08 # was treated under different temperatures (30, 38 and 42 ℃) The effects of high temperature stress and waterlogging under high temperature on the morphology, MDA content, SOD and POD activity and relative conductivity of lavender CAS08 # were studied. The results showed that lavender could adapt itself to high temperature within 15 days. Lavender could be over-summer under high temperature stress of 30, 38 and 42 ℃. The growth of lavender under the condition of high temperature of 30 ℃ and co-inundation water was blocked , Under the conditions of high temperature above 38 ℃ and flooding, the growth of lavender was blocked and died within a few days. It was presumed that under the condition of flooding, the soil produced poisonous and harmful substances, which damaged the root of lavender and lavender absorbed moisture and nutrition. And death.
