Morphophysiological responses of young oil palm plants to salinity stress [PDF]

open access: yesPesquisa Agropecuária Brasileira
: The objective of this work was to assess the morphophysiological characteristics and the ionic imbalance in the substrate, roots, and leaves of young oil palm (Elaeis guineensis) plants under different levels of saline stress, following a substrate ...

Water Status of Flower Buds and Leaves as Affected by High Temperature in Heat-Tolerant and Heat-Sensitive Cultivars of Snap Bean (Phaseolus vulgaris L.)

open access: yesPlant Production Science, 2003
In snap bean {Phaseolus vulgaris L.), flower and pod abscission causes yield reduction under high-temperature conditions. A high temperature enhances transpiration and thus may induce temporal water deficiency in plants in the daytime.

The Components of Leaf Water Potential II. Pressure Potential and Water Potential [PDF]

open access: yesAustralian Journal of Biological Sciences, 1967
The relation between the relative water content (R) and the pressure potential can be expressed through the coefficient of enlargement (e). The assumption that e does not vary with R is for many leaves a useful first approximation even when R is so low that pressure potential is negative. e is estimated at between 7 and 84 bars for various leaf types.

Water status and gas exchange of umbu plants (Spondias tuberosa Arr. Cam.) propagated by seeds and stem cuttings Estado hídrico e trocas gasosas de umbuzeiros (Spondias tuberosa Arr. Cam.) propagados por sementes e estaquia

open access: yesRevista Brasileira de Fruticultura, 2007
The experiment was carried out at the Embrapa Semi-Árido, Petrolina-PE, Brazil, in order to study the physiological responses of umbu plants propagated by seeds and by stem cuttings under water stress conditions, based on leaf water potential and gas ...

Effect of water-wall interaction potential on the properties of nanoconfined water

open access: yes, 2006
Much of the understanding of bulk liquids has progressed through study of the limiting case in which molecules interact via purely repulsive forces, such as a hard-core potential.

Effect of Water Stress and Rehydration on the Cluster and Fruit Quality of Greenhouse Tomatoes

open access: yesAgronomy, 2023
The water needs for tomato crops are very high and could limit the viability of cultivation in semiarid environments. There is no agreement among works on irrigation regarding the sensibility of the flowering period.

Fractional Fourier approximations for potential gravity waves on deep water [PDF]

open access: yes, 2003
In the framework of the canonical model of hydrodynamics, where fluid is assumed to be ideal and incompressible, waves are potential, two-dimensional, and symmetric, the authors have recently reported the existence of a new type of gravity waves on deep ...

Physiological drought responses improve predictions of live fuel moisture dynamics in a Mediterranean forest. [PDF]

open access: yes, 2018
The moisture content of live fuels is an important determinant of forest flammability. Current approaches for modelling live fuel moisture content typically focus on the use of drought indices.
