Effect of pre-imbibition and osmoconditioning on seed-germination in Phaseolus-vulgaris L. under water-stress
(Inst Tecnologia Parana, 1991-01-01)
The effect of osmoconditioning and controlled water sowing was analysed in seeds of Phaseolus vulgaris L. cv. carioca on germination under water stress conditions. The pre-sowing in water at low temperature to limit ...
Comparative morpho-biochemical responses of sunflower lines sensitive and tolerant to water stress
(Scientific Research Publishing, 2013-12)
Water stress is likely the most important factor that adversely affects plant growth and development. In our study two inbred lines of sunflower (Helianthus annuus L.) with contrasting behavior to water deficit, the inbred ...
Water stress indices for the sugarcane crop on different irrigated surfaces
(Univ Federal Campina Grande, 2016-10-01)
Sugarcane (Saccharum officinarum L.) is a crop of vital importance to Brazil, in the production of sugar and ethanol, power generation and raw materials for various purposes. Strategic information such as topography and ...
Water relations and leaf growth rate of three Agropyron genotypes under water stress
(Instituto de Histología y Embriología, 2002-12)
The effects of water stress on leaf water relations and growth are reported for three perennial tussock grass genotypes under glasshouse conditions. Studies were performed in genotypes El Palmar INTA and Selección Anguil ...
Constitutive gibberellin response in grafted tomato modulates root-to-shoot signaling under drought stress
(Elsevier B.V., 2018-02-01)
Plants are sessile organisms that must perceive and respond to various environmental constraints throughout their life cycle. Among these constraints, drought stress has become the main limiting factor to crop production ...
EFFECT OF TREATMENT WITH GROWTH-REGULATORS AND SCARIFICATION ON THE TOLERANCE TO WATER-STRESS IN SEEDS OF ORYZA-SATIVA LCVIAC-165
(Inst Tecnologia Parana, 1994-01-01)
The effect of treatment of seeds of Oryza sativa L. cv. IAC 165 with gibberellic acid, 6-benzyladenine and ethrel on the tolerance to the water stress were analysed. Gibberellic acid had no effect and 6-benzyladenine and ...
WATER REQUIREMENTS AND WATER USE EFFICIENCY OF CARROT UNDER DRIP IRRIGATION IN A HAPLOXERAND SOIL
(Chilean Society of Soil Science/Sociedad Chilena de la Ciencia del Suelo, 2011)
Peroxidase activity as an indicator of water stress in sweet pepper plants
(2006-10-01)
The purpose of the study was to evaluate the physiological and biochemical behavior of sweet pepper (Capsicum annuum L.) plants under different soil water availability conditions and the efficiency of the peroxidase (EC. ...
Ultraviolet-B and water stress effects on growth, gas exchange and oxidative stress in sunflower plants
(Springer, 2008-07-01)
The effects and interaction of drought and UV-B radiation were studied in sunflower plants (Helianthus annuus L. var. Catissol-01), growing in a greenhouse under natural photoperiod conditions. The plants received approximately ...
Analysis of gene expression profiles under water stress in tolerant and sensitive sugarcane plants
(Elsevier B.V., 2009-02-01)
Water stress decreases plant productivity. To detect genes expressed under drought conditions, we performed a gene expression study using drought tolerant (SP83-5073) and sensitive (SP90-1638) sugarcane plants. Gene ...
