Title

Evaluation of Water Requirement of Fraxinus rotundifolia Mill and Morus alba under Different Water Stresses in Arid Region (Case Studty: Robat Karim City)

Pages

  161-176

Abstract

 In arid and semi-arid regions that are affected by drought, maintaining and developing vegetation and green space are faced with serious challenge of the dearth of water. The purpose of this study is to compare the water requirement of Fraxinus rotundifolia Mill and Morus alba as common species in Robat Karim, located in the southwest of the Tehran province. This research was carried out in greenhouse and in the field and saplings of two tree species planted in a completely randomized design in the field and inside the pots. This research has two stages and each stage consists of several phases. The results showed that in Fraxinus rotundifolia Mill and Morus alba species, the fastest time to reach the MAD point respectively was 4 days (from 6 to 9 July), and 4 days (from 6 to 9 July, 10 to 13 July and 29 July to 1 August) in the greenhouse, and the fastest time to reach the MAD point respectively was 7 days (from 9 to 15 July and 9 to 15 August) and 9 days (from 12 to 20 June, 1 to 9 July and 2 to 10 September). The highest moisture consumption of Fraxinus rotundifolia Mill saplings used in the greenhouse and during different months on 11 to 12 July is equal to 19. 3% by volumetric water content,15. 6% weight water content or 38. 6 mm while the highest moisture consumption is used for Morus alba saplings in the greenhouse and during different months on July 6 to 7, equal to 12. 8% by volumetric water content. The weight of water content was 9. 83% or 32 mm. The highest moisture consumption used by Fraxinus rotundifolia Mill saplings in the field and during different months on July 1 to 2 was equal to 6. 2% by volumetric water content or 4. 3% by weight water content while the highest moisture consumption used by male Morus alba saplings in the field and during different months on 18 to 19 August was equal to 3. 75% by volumetric water content or 2. 7% by weight water content. Generally, the results of this study showed that Fraxinus rotundifolia Mill and Morus alba are classified according to the intensity of water requirement and irrigation frequency from high to low in the field and greenhouse.
