Sap flow could be used as physiological parameter to assist irrigation of screen house citrus nursery trees by continuous water consumption estimation. herein we report a first set of results indicating the potential use of the heat dissipation method for sap flow measurement in containerized citrus nursery trees.'valencia' sweet orenge [Citrus sinensis (L.) Osbeck] budded on 'Rangpur' lime (Citrus limonia Osbeck) was evaluated for 30 days during summer. heat dissipation probes and thermocouple sensors were constructed with low-cost and easily available materials in order to improve accessibility of the method. sap flow showed high correlation to air temperature inside the screen house. however, errors due to natural thermal gradient and plant tissue injuries affected measurement precision. transpiration estimated by sap flow measurement was four times higher than gravimetric measurement. improved micro-probes, adequate method calibration, and non-toxic insulating materials should be further investigated. |
