Strategies of two tropical woody species to tolerate salt stress
Pesquisa Florestal Brasileira, 2017 This study aimed to evaluate the leaf primary metabolism in two woody species, Sterculia foetida and Bombacopsis glabra. Both species have seeds rich in oil and they are largely found in regions with irregularities in water availability.

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

Hydrogen sulfide, potassium phosphite and zinc sulfate as alleviators of drought stress in sunflower plants [PDF]
Ciência e Agrotecnologia, 2020 Drought is the most harmful environmental factor crop productivity. Some chemicals are used in agriculture to mitigate the damage from this stress on plants. Therefore, we examined whether the spraying of zinc sulfate (ZS), potassium phosphite (KPhi) and

Leaf Water Potentials Measured with a Pressure Chamber [PDF]
Plant Physiology, 1967 Leaf water potentials were estimated from the sum of the balancing pressure measured with a pressure chamber and the osmotic potential of the xylem sap in leafy shoots or leaves. When leaf water potentials in yew, rhododendron, and sunflower were compared with those measured with a thermocouple psychrometer known to indicate accurate values of leaf ...
