The standing crop of Sasa Veitchii f. tyugokensis was examined to get information of the growth state of this species in the Shimane University Forest of Sambe.
Experimental plots were chosen in the stands which had been cut clearly three and five years ago respectively, and deciduous broad-leaved stands of about ten and twenty-five years old.
The factors measured were as follows.
1. number of crops, 2. total fresh weight, and dry weight of stems and leaves, 3. length and diameter of stems, 4. number of leaves, 5. leaf area.
The maximum standing crop of this species in this district was estimated at 15 tons/ha. for total dry weight, 5 tons/ha. for leaf dry weight and 5.7 ha./ha. for leaf area.
The growth state in each plot was discussed with reference to clear-cutting and reforestation.
