Drought is one of the main factors contributing to tree mortality worldwide and drought
events are set to become more frequent and intense in the face of a changing climate …

To face the increasing requirement for grains as the global population continues to grow,
improving both crop yield and quality has become essential. Plant health directly impacts …

Regular water management is crucial for the cultivation of tomato (Solanum lycopersicum
L.). Inadequate irrigation leads to water stress and a reduction in tomato yield and quality …

The yield and quality of tomato (Solanum lycopersicum L.) crops are lower when the plants
are exposed to drought stress. Drought stress can be prevented through timely irrigation if it …

In order to estimate the water stress of a plant, the natural frequency of the leaf-stalk system
was investigated. As a means of vibrating the leaf, acoustic radiation force was utilized, and …

Most existing greenhouse decision support systems only consider external environmental
factors, such as soil and atmosphere, rather than plant response. A conceptual plant …

Near infrared spectra obtained from leaf surfaces of Eucalyptus grandis seedlings were
calibrated against physiological measurements of plant water stress, namely: relative water …

A new noninvasive method for estimating the water stress of a plant was proposed. In order
to investigate this method, we first examined the characteristic frequency of an individual leaf …

抄録 The purpose of this research is to develop a laboratory-based near-infrared (NIR)
hyperspectral imaging system to measure the two-dimensional distribution of nitrate …

The purpose of this study is to measure the time variation of nitrate concentration in whole
lettuce plants throughout cultivation. Lettuce plants were cultivated in growth chambers …
