Title

Determination of the tolerance of sunflower to lead-induced stress

Marzena Wińska-Krysiak; Stanisław Gawroński; Marzena Wińska-Krysiak; et al. Journal of Elementology 2015. doi:10.5601/jelem.2014.19.4.721

Other claims from this paper (8)

Observation Most absorbed lead accumulated in sunflower roots, followed by stems and leaves.
Intervention effect Lead uptake per plant dry weight did not depend on the applied dose.
Intervention effect The 60 mg Pb dm-3 treatment significantly decreased sunflower dry weight content.
Observation At the highest lead treatment, 23.6% of total lead uptake was transported to stems and leaves.
Intervention effect The tested lead doses did not affect sunflower photosynthesis intensity.
Association Sunflower glutathione level varied by organ and lead treatment concentration.
Observation HaMT1 expression was observed only in sunflower stems.
Recommendation The authors identify sunflower cultivar Ogrodowy as promising for phytoremediation of lead-polluted soils.

Title

Effect of water stress on physiological traits of sunflower (Helianthus annuus L.) restorer lines

Other claims from this paper (4)

Intervention effect Water stress reduced leaf area index, total dry matter and crop growth rate by over 30%.
Intervention effect SPAD chlorophyll meter readings decreased by less than 10% under water stress.
Intervention effect Leaf temperature and proline concentration increased under water stress.
Observation RGP 21-P6, RGP 61-P1, RGP-61-P2, and RGP 95-P1 were superior for LAI, CGR, TDM and leaf temperature under water stress.

Other claims from this paper (12)

Intervention effect The w-1 mutant leaves showed no significant change in leaf conductance during detached-leaf dehydration
Intervention effect Detached w-1 leaves dehydrated strongly during the first 30 min
Intervention effect W-1 reduced stomatal aperture rapidly in response to water loss
Intervention effect ABA increased slightly in w-1 leaves after 2 h of stress
Intervention effect ABA increased 20-fold in W-1 leaves after 2 h of stress
Intervention effect Potted w-1 plants dehydrated quickly and lost turgor under water withholding
Intervention effect W-1 maintained positive turgor for a longer period under water withholding
Intervention effect Wild-type plants accumulated ABA in response to small changes in leaf water potential
Intervention effect The mutant changed ABA content and stomatal conductance only at very low water potentials
Association Conductance reduction in W-1 was paralleled by a rise in xylem sap ABA concentration
Intervention effect The mutant accumulated ABA in xylem sap only when soil and leaf water potential were dramatically reduced
Mechanism Low endogenous ABA and slow ABA synthesis appear to explain the high sensitivity of w-1 to water stress
