Long-distance signals regulating stomatal conductance and leaf growth in tomato (Lycopersicon esculentum) plants subjected to partial root-zone drying.
Tomato (Lycopersicon esculentum Mill. cv. Ailsa Craig) plants were grown with roots split between two soil columns. After plant establishment, water was applied daily to one (partial root-zone drying-PRD) or both (well-watered control-WW) columns. Water was withheld from the other column in the PRD treatment, to expose some roots to drying soil. Soil and plant water status were monitored daily ...
متن کاملStomatal conductance, growth and root signaling in young oak seedlings subjected to partial soil drying.
Leaf conductance, water relations, growth, and abscisic acid (ABA) concentrations in xylem sap, root apices and leaves were assessed in oak seedlings (Quercus robur L.) grown with a root system divided between two compartments and subjected to one of four treatments: (a) well watered, WW; (b) half of root system exposed to soil drying and half kept well watered, WD; (c) whole root system expose...
متن کاملStomatal conductance, growth and root signaling in Betula pendula seedlings subjected to partial soil drying.
Seedlings of Betula pendula Roth were grown with their root systems separated between two soil compartments. Four treatments were imposed: (i) adequate irrigation in both compartments (WW, controls); (ii) adequate irrigation in one compartment and drought in the other compartment (WD); (iii) drought in both compartments (DD); and (iv) half of the root system severed and the remainder kept well-...
متن کاملResponses of root growth and distribution of maize to nitrogen application patterns under partial root-zone irrigation
A field experiment was carried out to investigate the effects of varying nitrogen (N) supply andirrigation methods on the root growth and distribution of maize (Zea mays L.) in Wuwei,northwest China in 2011 and 2012. The irrigation treatments included alternate furrow irrigation(AI), fixed furrow irrigation (FI) and conventional furrow irrigation (CI). The N supply treatmentsincluded alternate ...
متن کاملA review on partial root-zone drying irrigation
Available fresh water resources are subjected to an ever-increasing pressure due to extensive agricultural water demand for irrigated lands. A long-term perspective in shortage of fresh water resources, especially in arid and semi-arid area, highlights an urgent solution for innovative irrigation strategy and agricultural water management. This paper is a review on the wide applications of the ...
