Title

PHYSIOLOGICAL AND BIOCHEMICAL RESPONSES OF PAGE MANDARIN ON CITRANGE ROOTSTOCK TO LOW TEMPERATURE STRESS

Pages

  1-12

Abstract

 Low temperature stress is an important environmental factor that limits CITRUS cultivation and yields. In this study, the effect of LOW TEMPERATURE STRESS on physiological and biochemical responses of Page MANDARIN on citrange rootstock (on two year old plants), in incubator condition (with 65±5 relative humidity and 15000 lux Light intensity) has been investigated. Experiment was conducted using randomized design including low temperature (9, 6, 3, 0, -3 and -6oC) and control treatments (25±2oC). The comparison of treatment means showed that the lowest total chlorophyll (1.513 mg/gr leaf FW), green color (61.25%) and leaf water content (33.55% leaf FW) were related to -6oC temperature treatment. The highest accumulation of proline (48 mg/gr leaf FW) was related to -3oC temperature and maximum amount of carbohydrate (55.3 mg/gr leaf FW), was obtained with 0°C temperature treatment. Also, the highest amount of water soaking (51-75%) and electrolyte leakage (75.66%) in -6oC temperature, lipid peroxidation (2.643 MDA mgr/gr leaf FW), antioxidant capacity (63.5%) and phenol (2.863 mg/gr leaf FW) in -3oC temperature, were observed. The highest SOD enzyme activity (8.44×104 IU/gr leaf FW) was related to 0oC temperature. It could be concluded that Page MANDARIN (on citrange rootstock) could tolerate the freezing stress up to -3oC by increasing of proline, carbohydrate (osmotic adjustment) and antioxidant capacity.
