Hormonal changes during salinity-induced leaf senescence in tomato (Solanum lycopersicum L.) [PDF]
, 2008 Leaf senescence is one of the most limiting factors to plant productivity under salinity. Both the accumulation of specific toxic ions (e.g. Na+) and changes in leaf hormone relations are involved in the regulation of this process. Tomato plants (Solanum

Estimating Leaf Water Content using Remotely Sensed Hyperspectral Data
CoRR, 2021 Plant water stress may occur due to the limited availability of water to the roots/soil or due to increased transpiration. These factors adversely affect plant physiology and photosynthetic ability to the extent that it has been shown to have inhibitory effects in both growth and yield [18].

Effective spectral characteristics of leaf for the remote sensing of leaf water content.
Journal of Agricultural Meteorology, 1988 サンゴジュ, キョウチクトウおよびクスノキの葉の水分量の変化に伴う400～2300nmの分光反射率の変化を夏期(8月)と冬期(2月)について調べた。相関分析の結果, 15の波長における分光反射率の組合わせで生ずる240種類の分光反射特性のうち, γ1650/γ1430(ここで, γ1650およびγ1430はそれぞれ1650nmおよび1430nmにおける分光反射率)という比反射率が葉の単位面積当りの水分量(LWC, mgH2O・cm-2)と最も相関が高く, しかも相関係数の植物種間差が最も少なかった。さらに, この比反射率では夏期と冬期の回帰直線の差異が少なかった。夏期における, 3植物種の葉に対する (標本数, n=90) 回帰直線はLWC=20.9(γ1650/γ1430)-22.8であり ...

Change of Leaf Dimensions and Air Volume with Change in Water Content [PDF]
Plant Physiology, 1973 To estimate how the transfer of water, oxygen, and carbon dioxide might be affected by leaf water deficit, we should know how the leaf geometry depends on water status. To study this relationship, I measured the length, width, total volume, and air space volume of leaf pieces in the relative water content range from 1.0 to about 0.65.

MEASURING LEAF WATER CONTENT USING MULTISPECTRAL TERRESTRIAL LASER SCANNING [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017 Abstract. Climate change is increasing the amount and intensity of disturbance events, i.e. drought, pest insect outbreaks and fungal pathogens, in forests worldwide. Leaf water content (LWC) is an early indicator of tree stress that can be measured remotely using multispectral terrestrial laser scanning (MS-TLS).

Using hyperspectral remote sensing data for retrieving canopy water content
, 2009 Canopy water content (CWC) is important for understanding functioning of terrestrial ecosystems. Spectral derivatives at the slopes of the 970 nm and 1200 nm water absorption features offer good potential as estimators for CWC.
