Abstract

The present study was carried out to detect water stress in teak (Tectona grandis L. f) seedlings using canopy air temperature difference (CATD). Seedlings were provided with four different levels of irrigation as treatments- irrigation at irrigation water (IW)/evapotranspiration (ET) = 1, 0.6 and 0.3 at weekly intervals and a control with no irrigation (IW/ET = 0). Canopy-air temperature difference (CATD) was recorded using an infrared thermometer. The non-water-stressed baseline (NWSB) was derived from CATD and vapour pressure deficit (VPD) in the well watered treatment (irrigation at 1.0 IW/ET). The lower baseline and upper baseline equations for CATD was developed. Crop water stress index (CWSI) was calculated using these baseline equations. CWSI responded to irrigation events along the whole season, and clearly detected mild water stress, suggesting extreme sensitivity to variations in plant water status. Non-irrigated IW/ET=0 showed a greater CWSI followed by treatment provided with irrigation at IW/ET=0.3 while the treatments with higher irrigation levels (IW/ET= 1 and 0.6) showed lower CWSI values. Observations on chlorophyll content and seedling height revealed that CWSI responded to water stress much before it upset growth or any other parameters of plants. Thus present series of investigations indicates the scope of CWSI for early detection of water stress which is easy to find out and less time consuming in irrigation scheduling as well as water management.
