Differential Sensitivity to Waterlogging
نویسنده
چکیده
Screening for tolerance of additional seedling types was continued on a reduced scale. J. nigra seedlings from 3 sources were no different than those of J. hindsii. ~. californica seedlings (1 source) had slightly greater average tolerance than those of J. hindsii. Single comparisons indicated no difference between J. honorei and J. hindsii and only a suggestion that 11anregian seedlings (1 source) might be slightly more tolerantthan progeny of common J. regia varieties. However, seedlings of a J. regia tree from India were considerably more tolerant than any other seed source of this species tested. This confirms the prediction that seed sources within a species with enhanced tolerance to WL do exist.

The Invasive Wetland Plant Alternanthera philoxeroides Shows a Higher Tolerance to Waterlogging than Its Native Congener Alternanthera sessilis
Plant invasion is one of the major threats to natural ecosystems. Phenotypic plasticity is considered to be important for promoting plant invasiveness. High tolerance of stress can also increase survival of invasive plants in adverse habitats. Limited growth and conservation of carbohydrate are considered to increase tolerance of flooding in plants. However, few studies have examined whether in...
متن کاملBulked Segregant RNA-seq Reveals Differential Expression and SNPs of Candidate Genes Associated with Waterlogging Tolerance in Maize
Waterlogging has increasingly become one of the major constraints to maize productivity in some maize production zones because it causes serious yield loss. Bulked segregant RNA-seq (BSR-seq) has been widely applied to profile candidate genes and map associated Single Nucleotide Polymorphism (SNP) markers in many species. In this study, 10 waterlogging sensitive and eight tolerant inbred lines ...
متن کاملConsequences of waterlogging in cotton and opportunities for mitigation of yield losses
Climatic variability, typified by erratic heavy-rainfall events, causes waterlogging in intensively irrigated crops and is exacerbated under warm temperature regimes on soils with poor internal drainage. Irrigated cotton is often grown in precisely these conditions, exposing it to waterlogging-induced yield losses after substantial summer rainfall. This calls for a deeper understanding of mecha...
متن کاملBarley responses to combined waterlogging and salinity stress: separating effects of oxygen deprivation and elemental toxicity
Salinity and waterlogging are two major factors affecting crop production around the world and often occur together (e.g., salt brought to the surface by rising water tables). While the physiological and molecular mechanisms of plant responses to each of these environmental constraints are studied in detail, the mechanisms underlying plant tolerance to their combined stress are much less unders...
متن کاملEffects of Waterlogging on Leaf Mesophyll Cell Ultrastructure and Photosynthetic Characteristics of Summer Maize
A field experiment was performed to study the effects of waterlogging on the leaf mesophyll cell ultrastructure, chlorophyll content, gas exchange parameters, chlorophyll fluorescence, and malondialdehyde (MDA) content of summer maize (Zea mays L.) hybrids Denghai605 (DH605) and Zhengdan958 (ZD958). The waterlogging treatments were implemented for different durations (3 and 6 days) at the third...
