空间电场对番茄初果期生长及生理特性的影响
Effects of space electric field on physiological characteristics of tomato during primary fruit stage
摘要
Abstract
[Objective]The effects of space electric field on the growth and physiological characteristics of tomatoes dur-ing primary fruit period were investigated by means of solar greenhouse experiment.[Methods]The experimental green-house and control greenhouse were used in this study.After the treatment of space electric field,the plant height and stem diameter of tomato were measured.Superoxide dismutase(SOD),peroxidase (POD),catalase (CAT)activities and chlorophyll contents with tomato leaves and the root activity were also determined during primary fruit stage.[Re-sults]The experiment result showed that the tomatoes with the space electric field treatment have better performances with comparison to the control greenhouse.It was found that the plant height was 19.3% and the stem diameter was 18.9% higher than the control one.Similarly,the space electric field treatment increased the activity of SOD、POD、CAT with tomato leaves in 13.7%,32.6% and 23.4% respectively.For the chlorophyll-a and chlorophyll-b,the in-creased yield were 17.3% and 54.4%.[Conclusion]Since the space electric field used in solar greenhouse could effec-tively improve the tomato growth performances,enzyme activity,chlorophyll content and root activity,it provides a feasible technical measure for green production of greenhouse crops such as tomatoes,and also provides some refer-ences for the chemical fertilizer and pesticide reduction and reduction.关键词
