Growth Response of Rice (Oryza sativa L.) to Drought:II. Varietal difference in transpiration under water stress and its related plant characteristics
Drought tolerance Humidity Leaf-water content Rice Sugar content Transpiration Varietal
2009/8/5
Transpiration of a rice plant under a low water potential of rooting medium and low air-humidity conditions was studied in order to evaluate varietal difference in response to water stress. Water stre...

Two Korean cultivars (cv. Hwangkeumkong, Danyeobkong) and one Japanese cultivar (cv. Enrei) were grown in the same pot under glasshouse conditions to investigate the influence of water deficit on the ...
Contributions of Capacity for Soil Water Extraction and Water Use Efficiency to Maintenance of Dry Matter Production in Rice subjected to Drought
Drought Dry matter production Rice Transpiration Water use efficiency
2009/7/28
Dry matter production rate in plants is indicated by transpiration rate (Tr) multiplied by water use efficiency (WUE). Our objectives were to establish which of WUE or Tr is dominant in contributing t...
