Construction and Application of a Novel C‐Vine Copula‐Based Multi‐Variate Ecological Drought Index

Irrigation and Drainage, EarlyView.
ABSTRACT A comprehensive ecological drought index capturing vegetation growth conditions and meteorological–hydrological variability is essential for assessing ecological drought and optimizing water resource management. This study selected soil moisture (SM), actual evapotranspiration (ET), land surface temperature (LST) and leaf area index (LAI) to ...

Analysis of diel variability in chlorophyll fluorescence [PDF]

, 1997
Examples of the diel variability in chlorophyll and beam attenuation are presented using data from moored in situ fluorometers and transmissometers, and from profiles of the beam attenuation coefficient and fluorescence.

The derivation of the formyl-group oxygen of chlorophyll b in higher plants from molecular oxygen. [PDF]

, 1994
The mechanism of formation of the formyl group of chlorophyll b has long been obscure but, in this paper, the origin of the 7-formyl-group oxygen of chlorophyll b in higher plants was determined by greening etiolated maize leaves, excised from dark-grown

Nitrogen‐doped graphene quantum dots tune the mineral, acid, and sugar profile of raisins in a cultivar‐specific manner

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Carbon dots are emerging as low‐toxicity nano‐biostimulants, but their effects on the integrated mineral, organic‐acid, and sugar profiles of grape berries remain poorly characterized, especially in indigenous Vitis vinifera L. cultivars.

Predicting grapevine stem water potential (Ψstem) using UV‐visible‐NIR spectroscopy across contrasting vineyard environments

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Climate change is intensifying water scarcity in viticulture, increasing the need for rapid and reliable tools to monitor vine water status. Spectroscopic techniques have emerged as promising approaches for rapid assessment of plant water status, although their robustness across different environments remains a key challenge.

Measurement of the Fluorescence Lifetime of Chlorophyll a In Vivo

Biophysical Journal, 1969
New measurements have been made of fluorescence lifetime (tau) of chlorophyll a in the algae Chlorella pyrenoidosa, Porphyridium cruentum, Anacystis nidulans, and in spinach chloroplast. tau-values of 0.6 and 0.7 nsec were obtained with green plants. Anacystis and Porphyridium gave a tau of 0.5 nsec.

Application of Organic Superabsorbent Cellulosic Polymers (OSCPs) and Cyanobacteria on Reduction of Aeolian Losses

Land Degradation &Development, EarlyView.
ABSTRACT Establishing biocrusts on sandy surfaces in harsh desert environments presents significant challenges due to extreme ecological conditions. To address these challenges, this study examined the effects of two organic superabsorbent cellulosic polymers (OSCPs)—carboxymethyl cellulose (CMC) and guar gum (GUA)—on the establishment of ...

Applications of nanocarrier‐delivered RNA interference in agricultural biological control (2009–2025)

New Plant Protection, EarlyView.
Despite 17 years of development, the effectiveness of nanocarrier‐delivered RNAi pesticide (NDRP) for agricultural biological control remains limited. The successful development of effective NDRP development requires the coordinated optimization of target gene selection and nanocarrier properties, including RNA dosage, multi‐gene targeting, protection ...
