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.

Increasing leaf hydraulic conductance with transpiration rate minimizes the water potential drawdown from stem to leaf. [PDF]
, 2014 Leaf hydraulic conductance (k leaf) is a central element in the regulation of leaf water balance but the properties of k leaf remain uncertain. Here, the evidence for the following two models for k leaf in well-hydrated plants is evaluated: (i) k leaf is

Evaluation of Argentine wild sunflower biotypes for drought stress during reproductive stage [PDF]
, 2012 As in several regions where sunflower production has moved to areas with limiting water availability, the search for water-stress tolerant genotypes has been intensified. Helianthus annuus ssp. annuus L.

Seasonal variation in soil and plant water potentials in a Bolivian tropical moist and dry forest [PDF]
, 2010 We determined seasonal variation in soil matric potentials (¿soil) along a topographical gradient and with soil depth in a Bolivian tropical dry (1160 mm y-1 rain) and moist forest (1580 mm y-1).

Use of leaf thickness sensors in horticultural crops [PDF]
, 2017 Changes in leaf thickness can be a rapid indicator of the plant’s water status and can therefore serve as an alarm signal for potential water deficits. Combining the use of continuous leaf thickness measurements with a mechanistic plant model describing ...
