Impact of late-season drought on water relations in a sparse canopy of millet (Pennisetum glaucum (L.) R. Br.) [PDF]

open access: yes, 1996
Although millet is known to be adapted to very dry conditions, little is known about its canopy water relations. The control of water loss and dehydration tolerance were studied during the grain filling for two cultivars presumed resistant and sensitive ...

Reevaluating the Activity of ZIF‐8 Based FeNCs for Electrochemical Ammonia Production

open access: yesAdvanced Functional Materials, EarlyView.
Though receiving much attention, the field of electrochemical nitrogen reduction reaction (eNRR) to ammonia is marked by doubts about whether this reaction is possible in aqueous media. This work sheds light on this question for iron single‐atom on N‐doped carbon (FeNC) catalysts—a class of well‐known catalysts that is also worth testing for the sister

The influence of biotization on the morphophysiological parameters of regenerants of Vaccinium uliginosum l. at the stage of adaptation to ex vitro conditions [PDF]

open access: yesBIO Web of Conferences
The study assessed the biotization of regenerated Vaccinium uliginosum plants (Patriot cultivar) during adaptation to ex vitro conditions. The morphophysiological state of the plants was assessed non-invasively using a 3D multispectral scanner ...

Diurnal patterns of wheat spectral reflectances and their importance in the assessment of canopy parameters from remotely sensed observations [PDF]

open access: yes
Spectral reflectances of Produra wheat were measured at 13 different times of the day at Phoenix, Arizona, during April 1979 using a nadir-oriented hand-held 4-band radiometer which had bandpass characteristics similar to those on LANDSAT satellites ...

Intra-specific variation in leaf attributes of four savanna tree species across a rainfall gradient in tropical Australia [PDF]

open access: yes, 2005
Leaf attributes of four savanna tree species were measured along a rainfall gradient (1650-950 mm per annum) in the Australian monsoon tropics. As the mean annual rainfall decreased, leaf thickness increased for three of these four species.

Functional Materials for Environmental Energy Harvesting in Smart Agriculture via Triboelectric Nanogenerators

open access: yesAdvanced Functional Materials, EarlyView.
This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...

Biometric Responses of Soybean to Different Potassium Fertilization Management Practices in Years with High and Low Precipitation

open access: yesRevista Brasileira de Ciência do Solo, 2018
Brazilian soybean producers commonly apply maintenance potassium (K) fertilization during cultivation to restore the K taken up by plants; however, this measure can modify the morphophysiological plant characteristics, since the functions of K are ...

Extracting scene feature vectors through modeling, volume 3 [PDF]

open access: yes
The remote estimation of the leaf area index of winter wheat at Finney County, Kansas was studied. The procedure developed consists of three activities: (1) field measurements; (2) model simulations; and (3) response classifications.
