Abstract:
Taking Eurohypnum leptothallum as test material,the effects of different shade levels on growth indexes (coverage,stem length) and physiological indexes (chlorophyll content,protective enzyme activity,MDA content,etc.) of shading treatment were studied with shading net,in order to provide reference for the cultivation and application of E.leptothallum.The results showed that the treatments with different shading degrees had very significant effects on the growth indexes and physiological indexes.The most suitable light intensity for the growth and development of E.leptothallum was about 1 060.17-2 763.83 lx.Too high or too low light intensity would inhibit it,and extremely high light would even lead to death.Correlation analysis showed that POD activity was significantly negatively correlated with cover,length,CAT,chlorophyll content,and significantly positively correlated with soluble protein content,so most of the information of growth physiological indicators under shading treatment could be represented by POD,and POD,SOD,CAT activity,soluble protein content,coverage,length and chlorophyll content could be used as the main indicators to study the response of E.leptothallum to environmental changes.In practice,it was recommended to use three layers of shading nets (black 4-pin type) for shading in summer,and two layers of shading nets for shading in autumn.
