2023年来,南京农业大学农学院智慧农业团队利用日光诱导叶绿素荧光(SIF)估测产量进行了深入研究。研究结果2023年9月22日以“The relationship between wheat yield and sun-induced chlorophyll fluorescence from continuous measurements over the growing season”为题,...
Solar Induced Chlorophyll Fluorescence (SIF), can be used as an indicator of stress in vegetation. Several scientific approaches have been made and there is considerable evidence that steady state Chl...
AIRFLEX is an optical sensor based on the Fraunhofer Line Discriminator principle applied in the atmospheric oxygen absorption bands, that measures simultaneously fluorescence at 687 nm and 760 nm. ...
To compare breaking of dormancy in relation with climatic conditions and reaction to late frost fir plants growing in sun, in shade and at magnesium deficiency were evaluated. Sprouting and chloroph...
Effects of 5-aminolevulinic acid (ALA) on photosynthetic characteristics of tomato grown under suboptimal conditions were investigated to evaluate the potential value of ALA spraying in vegetables. Th...
To compare breaking of dormancy in relation with climatic conditions and reaction to late frost fir plants growing in sun, in shade and at magnesium deficiency were evaluated. Sprouting and chlorophyl...
Fodder and fuel wood deficiency in the Himalayan region is well recognized. Rural inhabitants are exploiting these forest resources for their livelihood for generations which leads to severe deforesta...
叶绿素荧光技术是探知植物生理状态及其与环境关系的理想方法。太阳诱导叶绿素荧光可以利用夫琅和费暗线原理进行提取。阐述了夫琅和费暗线探测自然光条件下光合作用荧光的基本原理和方法,以及波长760nm叶绿素荧光探测仪的光学系统、仪器硬件组成及其各部分功能、仪器的软件设计。通过与ASD地物光谱仪器的对比试验表明,研制的太阳诱导叶绿素荧光测量的数据与地物光谱仪测量的数据相关系数都大于0.9。基于夫琅和费暗线原...
Chlorophyll Fluorescence Quenching and CO2 Exchange Rate of Mungbean (Vigna radiata (L.) Wilczek) Leaves without Epidermis.
Adaptive changes were studied comparatively in soybean and cotton grown in pots under four irrigation conditions i.e. normal irrigation (equal to the evapotranspiration of the crop), and 50%, 25% and ...
The seedlings of Oryza sativa L. cv. Nipponbare grown by hydroponic culture for 3 wks were treated with 75, 100, 150 and 200 mM NaCl for 14, 14, 6 and 3 days, respectively, and examined for chloroplas...
Effects of nitrogen (N) deficiency on photosynthetic gas exchange and photosystem II (PSII) photochemistry of flag leaves during grain-filling stage were investigated in six rice cultivars, Kasalath (...
The objective of this study was to establish the correlation of the chlorophyll meter (SPAD) readings with the contents of chlorophyll (Chl) and ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisc...
The top canopy leaves of mature trees are exposed to high solar radiation, regardless of whether they are climax or pioneer trees. We compared leaf physiology and morphology at the top canopies of a c...
The study was conducted to investigate the effect of ethanol at different concentrations (ET) on bougainvillea flower longevity and delay senescence in storage condition. The treatments were water con...
