| 摘 要： | 目的]研究不同温度光照水平组合对番茄生理指标的影响,为番茄栽培过程中合理的温光搭配提供理论依据.方法]在日光温室中,通过人工加温和补光,并设置不同的温光条件,测定番茄的生理指标,比较不同处理间差异,并对测定指标进行分析.结果]随着温度的增加,番茄叶片内Chla和Chlb含量增加,叶绿素a/b值下降,叶片游离脯氨酸（Pro）含量显著降低;在同一温度环境下,随着光照强度的增加,Chla和Chlb含量降低,而叶绿素a/b值、游离脯氨酸（Pro）含量、根系活力都呈增加趋势;但是,在自然温度处理环境,植株叶片内游离Pro含量高于增温3～4和6～7℃处理区,根系活力前期变化不明显,随着时间的延长根活力后期增加很快.结论]随着光照强度的增加,叶绿素含量降低,Pro含量也增加;随着温度的增加,叶绿素含量增加,Pro含量降低;但是,在温度相同条件下,随着光照强度的增加,根系活力增加.

| Abstract: | Objective] The effects of temperature and illumination level combination on tomato physiological indexes were studied to provide the theoretical basis for reasonable TPS in tomato cultivation process.Method] In sunlight greenhouse,by artificial heating and lighting,under different sowing conditions,the physiological indexes of tomato were measured,the differences between different processing were compared,and measurement indicators were analyzed.Result] With the temperature increasing,the tomato leaf Chla and Chlb content increased,chlorophyll a/b value decreased,and leaf free proline content decreased significantly.At the same temperature conditions,with the increase of light intensity,Chla and Chlb content reduced,and chlorophyll a/b value,free proline content and root activity increased.But in the natural temperature processing environment,plant leaf free proline content was higher than that of warming within 3-4 and 6-7 ℃ treatment area.Root activity early change wasn＇t obvious.With the extension of time,root activity increased quickly in the late period.Conclusion] With the increase of light intensity,chlorophyll content was lower,and Pro content increased.With the increase of the temperature,the chlorophyll content increased,and Pro content decreased.But in the same condition of temperature,with the increase of light intensity,root activity increased. |
