温室栽培对软枣猕猴桃叶片形态及叶绿素荧光特性的影响
Effects of greenhouse cultivation on leaf morphology and chlorophyll fluorescence characteristics of Actinidia arguta
摘要
Abstract
[Objective]The study aims to further study the leaf morphology and chlorophyll fluorescence characteristics of Actinidia arguta under greenhouse cultivation conditions,and to explore the differences of leaf photomorphogenesis between greenhouse and open field cultivation.[Methods]In this experiment,the 5-year-old plants of A.arguta varieties'Jialv'and'Kuilv'were used as test materials to determine the relative chlorophyll content and chlorophyll fluorescence parameters of leaves at different leaf ages un-der greenhouse and open field cultivation conditions.The differences in photomorphogenesis and chloro-phyll fluorescence characteristics under greenhouse and open field cultivation conditions were analyzed.[Results]The photomorphogenesis of A.arguta cultivated in greenhouse and open field was between 1-40 d leaf age,and the fluorescence characteristics of the same variety under different cultivation conditions tended to be consistent.After flowering,the fluorescence characteristics of the same variety under differ-ent cultivation conditions were quite different.The leaf area of A.arguta cultivated in greenhouse was larger and the content of chlorophyll b was higher,which was tending to shade leaf characteristics.The performance parameters such as PIabs were significantly lower than those of open field cultivation.The ab-sorption and capture ability of light energy was stronger,but the heat dissipation was higher.The energy used for electron transfer was lower than that of open field cultivation,and the chlorophyll fluorescence parameters showed adaptive changes to the environment.[Conclusion]The photomorphogenesis time of A.arguta leaves is 1-40 days after leaf expansion,that is,before flowering.The photomorphogenesis of A.arguta leaves in greenhouse cultivation is different from open field cultivation,and the photosynthetic capacity is decreased slightly with the increase of leaf area.Greenhouse cultivation changes in the chloro-phyll fluorescence characteristics of leaves to a certain extent and reduces photosynthetic performance.关键词
