LSV和LMoV侵染对百合光合生理和抗氧化酶活性的影响
Effects of LSV and LMoV infection on photosynthetic physiology and antioxidant enzymatic activity of lily
摘要
Abstract
Using the Lilium oriental hybrid ‘Siberian’as testing material,the effects of LSV and LMoV infection on photosynthetic physiology and antioxidant enzymatic activity of the lily were analyzed.The experimental results demonstrate that the contents of chlorophyll a,chlorophyll b and total chlorophyll of the lily leaves infected with LSV reduce by 1 5 .8%, 1 6 .6% and 1 1 .1%, respectively,compared with the healthy leaves,and those of the lily leaves infected with LMoV reduce by 24.3%,22.6% and 16.5%,accordingly.The net photosynthetic rate (Pn),intercellular CO2 concentration (Ci )and stomatal conductance (Gs )of LSV infected leaves decrease by 1 9 .2%, 13.4% and 15.1%,respectively,compared with the healthy leaves.Pn,Ci and Gs of LMoV infected leaves decrease by 50.6%,48.2% and 29.6%.Compared with control groups,the activities of superoxide dismutase (SOD),peroxidase (POD),polyphenol oxidase (PPO)and phenylalanine ammonia lyase (PAL)of the diseased lily leaves infected with LSV are enhanced by 24.6%,29.4%, 16.5% and 23.4%,respectively,while those of the sick lily leaves infected with LMoV are 10.6%, 18.2%,9.6% and 19.6%,respectively.It is shown that the photosynthetic physiology and antioxidant enzymatic activities of lily plant are affected by LSV and LMoV,and LMoV is more harmful than LSV in the aspect of extent of inj ury.关键词
