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...
متن کاملPaclobutrazol-Induced Biochemical Changes in Pomegranate (Punica granatum L.) cv. ‘Malas Saveh’ under Freezing Stress
Freezing injury is an important limiting factor in the production of pomegranate in Iran.The aim of the present study was to evaluate the effect of paclobutrazol (PBZ) on cold hardiness of pomegranate (Punica granatum L.) cv. ‘Malas Saveh’. Different concentrations of PBZ including 0 (control), 31, 62, 125 or 250 mg L–1 were sprayed on one-year-old plants in August and the electrolyte leakage o...
متن کاملSome growth and biochemical changes of viola (Viola × wittrockiana) and Snapdragon (Antirrhinum majus) ornamental plants to freezing stress
Exposure to freezing stress causes physiological, biochemical and molecular changes in plants, that are associated with reduced growth and development. In these areas, sensitive species are removed and the geographical distribution is changed. This study was conducted to evaluate some vegetative and biochemical responses of two cold-resistant ornamental plants, viola (Viola wittrockiana) and Sn...
