Study on Tolerance Screening of Woody Vegetation Restoring Species to High-Temperature

不同植物根部在高温胁迫下,植株的形态特征变化研究的结果表明:植物受到高温胁迫的伤害程度因物种、胁迫温度、胁迫时间的不同而不同;低于一定高温值的温度胁迫,植物受害程度不随时间延长而增加,而会自我修复。

In this paper, plant morphological characteristics were studied in the situation of the roots of plants were under high - temperature based on the test did on spontaneous combustion of coal waste piles. The results showed that： the plants damage degrees caused by high -temperature were different which were influenced by species of plant, stress temperature and stress time; when high - temperature fails below a certain value, the degrees of temperature stress on plants would not increase over time, on the contrary, the plants would self repair.
