Impact of Climate Trends and Drought Events on the Growth of Oaks (Quercus robur L. and Quercus petraea (Matt.) Liebl.) within and beyond Their Natural Range [PDF]

open access: yes, 2018
Due to predicted climate change, it is important to know to what extent trees and forests will be impacted by chronic and episodic drought stress. As oaks play an important role in European forestry, this study focuses on the growth response of sessile ...

Rice root genetic architecture: Meta-analysis from a drought QTL database [PDF]

open access: yes, 2009
During the last 10 years, a large number of quantitative trait loci (QTLs) controlling rice root morphological parameters have been detected in several mapping populations by teams interested in improving drought resistance in rice.

Shoot and Root Traits Contribute to Drought Resistance in Recombinant Inbred Lines of MD 23–24 × SEA 5 of Common Bean [PDF]

open access: yes, 2017
Drought is the major abiotic stress factor limiting yield of common bean (Phaseolus vulgaris L.) in smallholder systems in Latin America and eastern and southern Africa; where it is a main source of protein in the daily diet.

Multivariate analysis based on drought tolerance indices for screening drought tolerance in common bean (Phaseolus vulgaris L.)

open access: yesElectronic Journal of Plant Breeding, 2019
Twenty common bean (Phaseolus vulgaris L.) genotypes were evaluated based on drought tolerance indices through principal component analysis. All the indices were positively correlated with each other with the exception of drought susceptibility index ...

Drought-Resistance Index in Rice Backcross Lines after Anthesis

open access: yesPakistan Journal of Biological Sciences, 2007
In this study, many indexes correlated with drought resistance including yield components, chlorophyll content, the content of proline, the content of malondiadehyde (MDA), the activity of superoxide dismatase (SOD), the content of peroxides (POD) and catalase (CAT) activity soluble protein content and leaf area in flag leaves were measured under water

Roots, tubers and bananas: Planning and research for climate resilience [PDF]

open access: yes, 2017
The CGIAR Research Program (CRP) on Roots, Tubers and Bananas (RTB) includes vegetatively propagated staple crops linked by common breeding, seed, and postharvest issues, and by the frequency with which women are involved in their production and use. RTB

Discrimination of drought tolerance in a worldwide collection of safflower (Carthamus tinctorius L.) genotypes based on selection indices

open access: yesActa Agriculturae Slovenica, 2021
Improvement of elite safflower genotypes for drought-tolerance is hampered by a deficiency of effective selection criteria. The present study evaluated 100 genotypes of safflower in terms of their drought tolerance over a period of three years (2016–2018)

Index assessment of drought resistance of promising varieties of diploid winter rye in contrastive growing conditions

open access: yesAgrarian Bulletin of the, 2023
Abstract. Winter rye is grown in a variety of soil and climatic conditions, which indicates the evolutionary resistance to the action of abiotic stressors. Due to periodic spring-summer droughts in the conditions of the North-West region of the Russian Federation, the problem of drought tolerance in rye is of particular importance.
