Maize Leaf Elongation: Continuous Measurements and Close Dependence on Plant Water Status
TLDR
The transitional rapid growth after watering suggests that water deficit increased cell extensibility in monocots.Abstract:
A simple method was developed for measuring extensive intact leaves of monocots on a minute-by-minute basis. Growth was markedly reduced by a slight reduction in leaf water potential. When plants mildly deficient in water were irrigated, growth resumed virtually instantly. The transitional rapid growth aftr watering suggests that water deficit increased cell extensibility.read more

AquaCrop-The FAO Crop Model to Simulate Yield Response to Water: I. Concepts and Underlying Principles
TL;DR: The FAO crop model AquaCrop as mentioned in this paper is a water-driven growth engine, in which transpiration is calculated first and translated into biomass using a conservative, crop-specific parameter: the biomass water productivity, normalized for atmospheric evaporative demand and air CO 2 concentration.

Water stress, growth, and osmotic adjustment
TL;DR: Osmotic adjustment has long been known as a means by which higher plants adapt to salinity, with much of the cell osmotica being ionic and accumulated from the medium.

The importance of the anthesis-silking interval in breeding for drought tolerance in tropical maize
J. Bolaños,Gregory O. Edmeades +1 more
TL;DR: Results show that secondary traits are not lacking genetic variability within elite maize populations, and variation in grain yield under moisture stress is dominated by variation in ear-setting processes related to biomass partitioning at flowering, and much less by factors putatively linked to crop water status.

Crop Water Deficits
John E. Begg,Neil C. Turner +1 more
TL;DR: In this paper, the authors discuss the effects of water deficits on crop growth, crop development, and crop yield, and the differences in response of plants grown under controlled conditions and in the field are discussed.

Plant responses to water deficits, water-use efficiency, and drought resistance
TL;DR: Some of the physiological bases for differences among species in water-use efficiency and drought resistance are examined, with special attention given to CO 2 assimilation and transpiration.

Relationship of Water Potential to Growth of Leaves
TL;DR: It was concluded that leaves are not in equilibrium with the potential of the water which is absorbed during growth, and the nonequilibrium is brought about by a resistance to water flow which requires a potential difference of 1.5 to 2.5 bars in order to supply water at the rate necessary for maximum growth.

Growth Physics in Nitella: a Method for Continuous in Vivo Analysis of Extensibility Based on a Micro-manometer Technique for Turgor Pressure
TL;DR: Over long periods of treatment in a variety of osmotica the threshold value for extensibility and growth is seen to fall to lower values to permit resumption of growth at reduced turgor.

Rapid growth inhibition of gherkin hypocotyls in blue light1
TL;DR: In this article, the elongation of dark-grown gherkin hypocotyls has been recorded continuously in darkness and on exposure to blue, red or far-red light, and evidence was obtained that the inhibition of elongation in blue light is not mediated by the phytochrome and high energy reactions, but that a specific blue-light absorbing pigment is involved.
