Genetic Architecture of Winter Hardiness and Frost Tolerance in Triticale
Abiotic stress experienced by autumn-sown crops during winter is of great economic importance as it can have a severe negative impact on yield. In this study, we investigated the genetic architecture of winter hardiness and frost tolerance in triticale. To this end, we used a large mapping population of 647 DH lines phenotyped for both traits in combination with genome-wide marker data. Employi...
متن کاملInterrelations between photoperiod, frost hardiness and sulfhydryl groups in cabbage.
Hardening of SD (8 and 12 hrs) and LD (18- and 24-hr photoperiods) cabbage plants in stages at temperatures starting with + 5 degrees and ending with - 3 degrees led to the following changes:Soluble protein plus nonprotein N showed a net increase only in the SD plants. In both SD and LD plants, it decreased to a minimum toward the end of the first stage of hardening, increased to a maximum in t...
متن کاملInteractions of low temperature, water stress, and short days in the induction of stem frost hardiness in red osier dogwood.
The induction of stem frost hardiness by low temperature, water stress, short days, and their combinations in 2- and 4-month-old growing dogwoods (Cornus stolonifera) were investigated. When plants were subjected to more than one factor, the increased hardiness was the sum of the effects of the individual factors involved. No interactions among these factors on hardiness were observed during a ...
متن کاملInduction of Frost Hardiness in Stem Cortical Tissues of Cornus stolonifera Michx. by Water Stress: I. Unfrozen Water in Cortical Tissues and Water Status in Plants and Soil.
Water supply and day length were varied in cold hardiness studies of red osier dogwood plants (Cornus stolonifera Michx.). The frost killing temperature, the content and freezing of stem cortical tissue water along with soil moisture content and tension were evaluated. Seven days of water stress in long and short day photoperiod regimes caused a rapid decrease in soil moisture content and plant...
متن کاملChanges in Frost Hardiness of Stem Cortical Tissues of Cornus stolonifera Michx. after Recovery from Water Stress.
Moderate water stress increases frost hardiness in many woody plants but little attention has been given to changes in hardiness after recovery from water stress. Tests were carried out to examine how much water stress-induced frost hardiness remained when plants were rewatered under different day length regimes. Red osier dogwood plants (Cornus stolonifera Michx.) were water-stressed at normal...
