Hormonal changes induced by partial rootzone drying of irrigated grapevine.
Partial rootzone drying (PRD) is a new irrigation technique which improves the water use efficiency (by up to 50%) of wine grape production without significant crop reduction. The technique was developed on the basis of knowledge of the mechanisms controlling transpiration and requires that approximately half of the root system is always maintained in a dry or drying state while the remainder o...
متن کاملSap fluxes from different parts of the rootzone modulate xylem ABA concentration during partial rootzone drying and re-wetting
Previous studies with partial rootzone drying (PRD) irrigation demonstrated that alternating the wet and dry parts of the rootzone (PRD-Alternated) increased leaf xylem ABA concentration ([X-ABA]leaf) compared with maintaining the same wet and dry parts of the rootzone (PRD-Fixed). To determine the relative contributions of different parts of the rootzone to this ABA signal, [X-ABA]leaf of pott...
متن کاملwater relations of the tomato plant under partial rootzone drying (prd)
the world is facing a dwindling supply of water, therefore deficit irrigation is becoming more of a necessity than a choice. partial rootzone drying (prd) is a new water saving irrigation technique where at each irrigation time only one part of the rootzone is watered. the un-irrigated part is watered during the next irrigation. we explored the potential of prd for `petopride´ processing tomato...
متن کاملResponse of New Cotton Variety (Rassafa) to Nitrogen Fertilizer and Partial Rootzone Drying Drip Irrigation
Received: July 25, 2017 Revised: November 23, 2017 Accepted: December 17, 2017 Abstract: Introduction: Due to the water shortage and dry Mediterranean condition, determination of water and nitrogen (N) fertilizer requirements is a major challenge for crop production and environment protection. A field experiment was carried out for two consecutive years (2014 and 2015) to evaluate the response ...
متن کاملRoot water potential integrates discrete soil physical properties to influence ABA signalling during partial rootzone drying.
To investigate the influence of different growing substrates (two mineral, two organic) on root xylem ABA concentration ([ABA](root)) and the contribution of the drying root system to total sap flow during partial rootzone drying (PRD), sunflower (Helianthus annuus L.) shoots were grafted onto the root systems of two plants grown in separate pots. Sap flow through each hypocotyl was measured be...
