Can Environmental Stressors Determine the Condition of Ecological Plant Groups?

Beata Koim-Puchowska; Piotr Kamiński; Piotr Puchowski; et al. Plants 2024. doi:10.3390/plants13111550

Other claims from this paper (13)

Observation Green parts indicate environmental stress better than roots.
Mechanism Higher MDA damage is related to toxic ion transport into shoots.
Association High salinity was the main factor inducing growth.
Association High pH correlated with proline increase in glycophytes and alkaligrass.
Association Common Glasswort contrasted with the other plants in the proline response.
Mechanism Proline may allow osmotic adjustment in reeds and alkaligrasses.
Mechanism Proline may have another function in Elder.
Observation Glasswort accumulates large amounts of sodium.
Observation Sodium accumulation was interpreted as more energy effective than proline accumulation.
Association Organic matter affects growth and proline levels.
Observation Elder was the most salt sensitive of the compared species.
Association Salinity affects halophyte distribution.
Association Thick reeds affect halophyte distribution through competition.

Other claims from this paper (14)

Intervention effect Nutrient omission reduced rice-maize yields on calcareous soil.
Observation Nitrogen was the most limiting nutrient in the hybrid rice-maize system on calcareous soil, followed by P and K.
Intervention effect Omission of Zn affected crop yields more than omission of S.
Intervention effect The effect of Zn omission was more prominent in hybrid maize.
Intervention effect Nutrient uptake in the cropping system declined by 58% when N was systematically removed from the fertilization schedule.
Intervention effect Nutrient uptake in the cropping system declined by 37% when P was systematically removed from the fertilization schedule.
Intervention effect Nutrient uptake in the cropping system declined by 34% when K was systematically removed from the fertilization schedule.
Intervention effect Nutrient uptake in the cropping system declined by 31% when S was systematically removed from the fertilization schedule.
Intervention effect Nutrient uptake in the cropping system declined by 25% when Zn was systematically removed from the fertilization schedule.
Intervention effect Sustainable Yield Index of the cropping system was highest in the ample balanced fertilizer treatment.
Intervention effect Unfertilized checks reduced hybrid rice-maize system yield by 9 t/ha.
Intervention effect Unfertilized checks reduced inbred rice-maize system yield by 5 t/ha.
Association Cropping system productivity showed a synergistic effect of seed and nutrients.
Recommendation Adoption of hybrids in the rice-maize system and balanced nutrient management are the best management practices for sustainable food production.
