Abstract
The object of this experiment is to study the ecological effects of altitude on orchard grass (Dactylis glomerata). Details of the four locations used for this experiment and the method are mentioned in the first report of this series. Results obtained are as shown in Table 1 and 2. At the lowest location the summer depletion of the plant growth was the most prominent and the survival percentage after summer passing was much less than at the other locations. And the plant showed progressively more vigorousg rowth, higher survival percentage, larger dry weight, less injury by plant diseases and higher content percentage of crude protein and crude fiber with increasing altitude
