据《果树学报》2013年第2期《缺镁对‘纽荷尔’脐橙不同叶龄叶片叶绿素及荧光特性的影响》(作者凌丽俐等)报道,为了探明缺镁对不同叶龄叶片叶绿素合成与荧光特性的影响,为纽荷尔脐橙高产优质提供理论指导。以2年生枳砧纽荷尔脐橙为试材,定期测定不同叶龄叶片的相对叶绿素含量和荧光参数,研究缺镁胁迫条件下纽荷尔脐橙不同叶龄叶片的叶绿素合成与荧光特性的动态变化。结果表明,随着缺镁时间推移不同叶龄叶片的相对叶绿素含量和Fv/Fm呈显著降低趋势,2龄叶相对叶绿素含量和
According to the Journal of Fruit Science, No. 2, 2013, “Effects of Magnesium Deficiency on Chlorophyll and Fluorescence Properties of ’Newhall’ Navel Orange Leaves at Different Leaf Ages’” (by Lingli Li et al.) Reported that in order to find out the effects of magnesium deficiency on chlorophyll synthesis And fluorescence characteristics of Newhall navel orange to provide high yield and quality theoretical guidance. The relative chlorophyll content and fluorescence parameters of leaves of two-year-old Poncirus trifoliata were determined periodically to study the dynamic changes of chlorophyll biosynthesis and fluorescence of leaves of Newhall navel orange at different leaf ages under magnesium deficiency stress . The results showed that the relative chlorophyll content and Fv / Fm of leaves at different leaf ages decreased significantly with the time lapse, and the relative chlorophyll content
