| Abstract | ||
| Quantitative and qualitative forage yield of ten genotypes of Festuca arundinacea (6 Iranian and 4 foreign genotypes) with three irrigation treatments (every 7days, every 14 days and every 21 days) at three replicates were determined and were investigated in a split plot statistical design during 2001-2003 in Research field of Forests and Rangelands Institute. In summer cut, total dry matter production and protein, carbohydrate, digestibility of forage, weight of 1000 seeds, length of cluster, RWC and number of stomats of leaf surface were determined. There was a significant difference among different irrigation treatments and genotypes. Barracco with 5/8, 0/9 and 0/75 tons per hectare have the most dry matter, protein and carbohydrate yield and 627 genotype have the most digestibility. The number of stomata on the adexiol per unit on leaves (leaf surface) were increased by increasing the water stress. But there was not any changes in stomata number and epidermic cells ratio. Relative water content (RWC), 1000 kernel weight and ear length were decreased by increasing the water stress. Barracco genotype had better performance in this study and it could adapt itself with karaj environment. | ||
