Problems solved by technology

However, there is no research on the effects of polyamines on the physiological and biochemical characteristics of Ilex chinensis under salt stress. Therefore, a method for the study of the effects of polyamines on the chlorophyll fluorescence characteristics of Ilex chinensis under salt stress is proposed. The effect of amines on the photosynthetic and fluorescence characteristics of Ilex North America under different degrees of salt stress is aimed at understanding the response mechanism of Ilex North America under salt stress, and providing a theoretical basis for the evaluation of salt tolerance and salt resistance screening of Ilex North America

Abstract

The invention discloses a method for researching influence of polyamine on ilex verticillata chlorophyll fluorescence characteristic under salt stress. Through setting treatment, measurement on content and parameters and data analysis, the method is capable of scientifically and reasonably quantifying influence of salt stress on ilex verticillata chlorophyll content and fluorescence parameters, promoting the salt stress response mechanism of ilex verticillata, furthermore, researching influence of polyamine on growth of ilex verticillata, and indicating that exogenous polyamine can effectively alleviate the influence of salt stress on the chlorophyll fluorescence characteristic of ilex verticillata, thereby improving the photosynthesis, improving the saline-alkaline tolerance of ilex verticillata, achieving a certain theoretical guidance effect on promotion of ilex verticillata growth in a coastal region and providing certain theoretical basis for salt tolerance evaluation and salt resistance screening of ilex verticillata.

Description

【Technical field】 [0001] The invention relates to the technical field of the growth research of North American holly under salt stress, in particular to a research method for the influence of polyamines on the chlorophyll fluorescence characteristics of North American holly under salt stress. 【Background technique】 [0002] Salt stress is one of the important limiting factors affecting plant growth and development. Salt stress causes the physiological and biochemical factors such as plant water content, turgor pressure, photosynthesis and antioxidant system to decrease obviously. degree of inhibition; polyamines play an important role in the regulation of plant growth and development, many studies have reported that polyamines can significantly enhance the salt tolerance of plants, under salt stress polyamines can regulate the activity of various enzymes and can combine with photosynthesis Mechanism combined to alleviate the impact of salt stress on photosynthesis.
