| Correlative analysis among water use efficiency and others traits of wheat varieties A115 and 4185 was studied by pot cultivation under rainproof shelter with 3 alternate drying-wetting treatments. The results showed that water use efficiency of yield was positively related with plant height, photosynthesis rate, transpiration rate, ear number, dry matter per plant and yield, but not significantly related with other measured traits; Water use efficiency of leaf was negatively related with kernel number per ear, tiller number per plant, stomata conductance and transpiration rate, but not significantly related with the other traits. |
