On the influences of tread-pressure and mowing on the growth of Japanese lawn grasses varieties

Abstract

The experiments were carried out to know the influences of tread-pressure and mowing on the growth of Japanese lawn grasses varieties (No-shiba, Chu-shiba, Korai-shiba I, Korai-shiba II, Korai-shiba III, Kara-shiba, Chosen-shiba, Hime-shiba, Meyer Zoysla, Emerald Zoysia, Zoysia matrella (native to Philippine) and Z. tenuifolia (native to Guam I.)), and the following results were obtained.
(I) Generally, Japanese lawn grasses were comparatively strong to the tread, but the extremely small varieties were somewhat weak. In case of the moderate tread-pressure (I-5 times/day), as a rule, the length of stolons, the numbers of stolons, nodes, leaves and roots of Japanese lawn grasses varieties were increased, and their turf grew thick. While, in case of the over tread all decreased.
(2) Japanese lawn gras3es varieties were comparatively strong to the mowing. In case of the moderate mowing (the larger varieties-I time/2-4 weeks, the smaller varleties-I time/I-4 weeks), as a rule, the numbers of stolons, nodes, leaves and roots were increased, and their turf grew thick. While, in case of the over mowing, all decreased.
