Freezing tolerance of conifer seeds and germinants.

Survival after freezing was measured for seeds and germinants of four seedlots each of interior spruce (Picea glauca x engelmannii complex), lodgepole pine (Pinus contorta Dougl. ex Loud.), Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) and western red cedar (Thuja plicata Donn ex D. Donn). Effects of eight seed treatments on post-freezing survival of seeds and germinants were tested: dry, ...

Evaluation of freezing tolerance in olive cultivars by stomatal density and freezing stress

Selection of frost tolerant cultivars and understanding the mechanisms of frost hardiness could help to improve freezing resistance in olive plants. Olive cultivars may differ in frost hardiness due to differential survival of specific organs. The aim of this study was to screen different olive cultivars based on their stomatal density and metabolic modifications under cold conditions. The ‘Zar...

Freezing Tolerance of Chickpea Genotypes in Controlled Conditions

Lack of chickpea cultivars tolerant to extreme freezing is a limiting factor for autumn planting of this crop in cold areas. In this study, 58 Kabuli-type chickpea genotypes and a control (an international sensitive genotype) were planted in pots and first exposed to -10°C and then to -15°C after being acclimated in natural conditions. No destructive effect of -10°C was observed in plants. So, ...

Predicting Arabidopsis Freezing Tolerance and Heterosis in Freezing Tolerance from Metabolite Composition

Heterosis, or hybrid vigor, is one of the most important tools in plant breeding and has previously been demonstrated for plant freezing tolerance. Freezing tolerance is an important trait because it can limit the geographical distribution of plants and their agricultural yield. Plants from temperate climates increase in freezing tolerance during exposure to low, non-freezing temperatures in a ...

Effects of Glycerol and Salicylic Acid on Freezing Tolerance of Iranian Petunia (Petunia hybrida L.)

The aim of this study was to investigate the effects of glycerol (GL) and salicylic acid (SA) on freezing tolerance of Iranian Petunia (Petunia hybrida). For this purpose, a factorial experiment based on completely randomized design with three replications was conducted under controlled conditions. The first factor was temperature (0 and -4 °C) and the second factor was spraying with anti-stres...
