The esparto is a densely tufted evergreen native to Mexico , Argentina, Texas, a perennial ornamental grasses , leaves slim soft , long flowering period , strong resistance , extensive management, is widely used in gardens , solid slope protection , indoor green . In recent years , the greenhouse effect of increasing global average temperature gradually increased , no doubt the harm of high temperature on plant ornamental grasses heat resistance has become a new topic of current research . The experiment with a variety of esparto \the induction of the \to salicylic acid ( SA ) and thermal acclimation induced heat resistance , analysis of the impact of different treatments on plant physiology and biochemistry . Confirms some of the points of the previous also reached a different point of view : 1 confirms the high temperature stress can plant leaf relative conductivity increases , malondialdehyde and proline increased , decreased chlorophyll content , but salicylic acid or heat acclimation induced can alleviate the damage caused by the high temperature environment for the plants . 2 salicylic acid treatments , 0.5 mmol / L of salicylic acid to more effectively improve the heat resistance of the \\4 by analyzing the different treatment under high temperature stress \5 results suggested that the negative correlation or a positive correlation between the time of the soluble protein content and high temperature stress does not exist , but with a certain degree of self-adaptive .
