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 کاملQuantifying the threshold frost hardiness for over-wintering survival of wheat in Iran, using simulation
The value of frost tolerance in wheat is increased with decreasing the temperature in late autumn and/or early winter (phase I, acclimation), then shows plateau state for a period with the coldest temperature (II), finally appears to decrease with warming the temperature (III, de-acclimation). This study was aimed to determine the threshold frost hardiness in wheat for avoiding ...
متن کاملTemperature control of the development of frost hardiness in two populations of Leptospermum scoparium.
Seedlings of Leptospermum scoparium J.R. et G. Forst (manuka) originating from seed from a low altitude coastal site (Auckland) and from a high altitude inland site (Desert Road) were grown for 96 days in four controlled environments to compare the relationship between growth temperature and frost hardening. Day/night temperature treatments were 12/6, 12/3, 12/0 and 12/-3 degrees C. Frost hardi...
متن کاملThe effect of exposure to NO2 and SO2 on frost hardiness in Calluna 6ulgaris
Heather (Calluna 6ulgaris) was grown in pots in a natural heathland soil and exposed in outdoor fumigation chambers (‘solardomes’) to 40 nl l of both nitrogen dioxide (NO2) and sulphur dioxide (SO2) simultaneously. Plants exposed to NO2 and SO2 for 8 months over a growing season (February–November) showed increases in the growth of shoots (+37%) and the whole plant (+15%) and a raised ratio of ...
